This tube part number 632766 was added to stabilize the atmospheric pressure in the bowl, improving the run quality. This was done in combination with carburetor calibration changes. This tube is serviceable and must be installed to a precise depth using tool part number 670343 to maintain emission standards and prevent blockage of the atmospheric vent passage. Do not use this tube on applications that it was not originally on. Always verify that the engine requires this tube by checking the parts list. COLD START HANG TAG Tecumseh has gone through extensive efforts to educate the customer in the proper procedures used to prime today’s emissions engine. If a customer comments about an engine that is hard to start, it may be helpful to ask them to demonstrate the method they use when priming. In most cases there is not any engine problem and we have found improper priming is the cause. Most recently we have created a hang tag with instructions on the “Thumbs Up” five prime technique. This cold start procedure is outlined in the owners manuals and is illustrated by the use of a decal on the blower housing or fuel tank on some engines. It requires that the thumb be used to prime because the thumbs larger surface area covers the primer bulb better. Remember always to wait two seconds between primes. HOW THE NEW EMISSIONS PRIMER WORKS The primer used on emission grade carburetors has been designed to provide the precise amount of fuel being delivered with each compression. This style of primer must squarely make contact with the inside casting surface of the carburetor before any prime occurs. This will prevent air from being forced back into the air filter and send the prime charge into the carburetor. A brief delay of two seconds between each prime will assure that the primer has recovered ample air to provide an adequate prime charge. PRIMER CONTACT AREA 6 www.mymowerparts.com For Discount Tecumseh Engine Parts Call 606-678-9623 or 606-561-4983 LEV/VLV VALVE STEM SEAL CHANGE A design change has been made to the intake valve stem seal used on LEV and VLV engines. The seal area which makes contact with the casting surface in the valve box has been enlarged to improve sealing. A better seal on the valve stem will allow the elimination of an o-ring that had been used on engines prior to this. We have also reissued Service Bulletin “406” which references kit number 730617 to include the new seal. Removal of the intake valve may cause damage to the seal, always install a new seal when this type of repair work is done. OLD NEW RAISED SEAL VLV AIR BAFFLE CHANGE The fiber baffle/gasket used between the carburetor and cylinder block on the VLV engine has been changed to a metal baffle. A gasket is used on each side of the metal baffle which replaces the fiber gasket (an instruction sheet is included for installation). This baffle allows for cooler running carburetor bowl temperatures eliminating the occasional carburetor popping during high ambient temperature operation. We also created a bendable high speed adjustment tab as part of the baffle for fixed speed applications. Speed adjustments if necessary are done by bending the tab to the right to increase speed and to the left to decrease speed. FIXED SPEED TAB SERIES 11 CARBURETOR This is possibly the most innovative and exciting primer type carburetor to be introduced since emissions standards were established. The series “11” carburetor is being released in limited quantities this year. Its design helps to eliminate the cold blooded nature of emissions engines by drawing fuel from a reservoir during the first minute of operation giving it smoother start up and warm up characteristics. This will give the engines using this carburetor the personality of one built prior to the emissions standards. The external physical package is identical to that of a series "8" carburetor. Removing the bowl will expose the welch plug used to cover the extended prime fuel chamber. There is also an additional passage way along side the center leg which feeds the fuel into this chamber when the carburetor is primed. During start up operation, the fuel is drawn from this chamber into the venturi until the chamber is empty, at which time normal operation is resumed. When cleaning an emissions carburetor remember the passages are extremely small. The best method for cleaning this carburetor is to remove all welch plugs and use carburetor cleaner and compressed air to clean the passages. It is not recommended to soak the carburetor in carburetor cleaner. 7 www.mymowerparts.com For Discount Tecumseh Engine Parts Call 606-678-9623 or 606-561-4983 VLV NO BOTTOM DRAIN FLANGE The VLV engine now has an option available to OEM’s with no oil drain on the bottom of the mounting flange. This will be available for applications such as generators, pumps and pressure washers. In place of the bottom drain there is an optional side drain. If an OEM would choose to use this flange on a rotary lawnmower application, removing the oil may be accomplished by draining the oil out of the fill tube. This flange has been available since July 1998. NON MACHINED OIL DRAIN HM CLIMATE GUARD™ KIT Climate Guard™ for HM engines is available on original equipment and will be used exclusively on Generac product for 1999. However, there is now a kit available for existing engines. If you have emissions or nonemissions engines that are used during both summer and winter seasons, you can now convert it to the Climate Guard™ system by using part number 730630. Typical applications that could use this system are log splitters and generators. LEV 80 NEW OFFERING The LEV 80 is a new 3.5 hp engine being offered this year. It has been designed using the technology developed in the LEV engine with the straight valve train used in the TVS engines. This engine has the same cylinder fin design and flow through valve cooling system that allows the LEV to run at reduced cylinder block temperatures. It is being used on opening price point units and puts an offering in the market place that has the quality, and durability of the higher price units. TORO FUEL TANK BAFFLE The OHSK 120 used on Toro snow throwers has a foam baffle added to the fuel tank. This will prevent splashing and inconsistent fuel flow when there is less then an inch of fuel inside the tank. The foam baffle stabilizes the fuel supply to prevent the occasional fuel starvation situation. The material is similar to that used in race car fuel cells and is impervious to all of today’s fuels within our standard fuel guidelines. The part number for the complete tank assembly is 37290. 8 www.mymowerparts.com For Discount Tecumseh Engine Parts Call 606-678-9623 or 606-561-4983 OHH 7 AMP D.C. CHARGING SYSTEM This series of engines has quickly become one of the most popular engines in the industry. It is now poised to expand into markets that require a higher output charging system. A 7 Amp D.C. charging system is now available on OHH/OHSK 50-70 model engines. This reliable compact power plant can now be applied to those applications that require higher battery starting capabilities. The alternator part number is 611233. Upgrading existing equipment will require that the flywheel be changed to accommodate the alternator which uses internal magnets. 220 VOLT STARTERS There is now a 220 volt 50 hertz starter available for countries outside the US and Canada. These starters, part number 37102 (H30-35, HS40-50, HSK34, HSSK4050, OHSK50-70) and 37217 (HM70-100, HMSK70-100, OHSK80-120) have only a limited number of parts that are serviceable due to European Community regulation. None of the internal parts can be serviced. Only the parts from the engagement nut to the cap are serviceable externally. The starter does not include a power cord because of the multiple options used in different countries. DIPSTICK COUNTER BORE OHH On many applications the OHH engine uses a dipstick gauge that threads directly into the cylinder cover. Checking the oil has been a challenge at times because of difficulty reinstalling the oil gauge without cross threading. This situation has been corrected by machining a counter bore in the oil gauge hole and adding a 45° chamfer to the lead in thread making reinstallation easier. Remember to instruct the customer to clean the area around the dipstick prior to removal. COUNTER BORE ONE CONNECTING ROD FOR ALL In our continuing effort to reduce the inventory required to service our engines, a change has occurred to the small frame connecting rod. When you order connecting rod part number 32875A, you will receive an instruction sheet explaining which oil dipper, if any, is used. An example is the H30-HS50 which uses dipper number 32654. The same connecting rod is used on small frame overhead valve engines but uses the longer 36611 dipper. Please follow the instruction sheet carefully. Remember always assemble the rod and cap with the match marks facing out. 9 www.mymowerparts.com For Discount Tecumseh Engine Parts Call 606-678-9623 or 606-561-4983 OHSK NEW HORSEPOWER We are very pleased to expand our overhead valve engine line with three new models based on the HM series engine. There are three horsepower offerings being used in this seasons snow product. They are OHSK 80, 90 and 110. NEW RE-POWER PACKAGES With the change to emission product, several models of engine have been obsoleted. We have worked with our applications group to develop replacement for several application. The following kits are available from your engines source: REPOWER PACKAGES 205128 - OHH50 205130 - OHH50 208106 - HM80 208120 - HM80 Troy Bilt Pony - Part Number 205128 OHH 50, with features including 3/4” crankshaft, extended cam, mounting instructions and reverse belt.

They are available in all states with the exception of California. These engines are able to meet the E.P.A. emissions standards for hand-held equipment through use of a fixed jet carburetor and cylinder port timing changes. The engines will be available in early 1999, under service part number’s 800175 and 800176. Please consult your parts lookup system or the service engine specification book to locate the correct one. EMISSIONIZED AV520/600 The AV series engines used on post hole diggers and ice augers has been changed in several areas to meet the E.P.A. emissions regulations for hand-held product. These improvements include changes to cylinder port timing and the carburetor being made customer tamperproof. The carburetor changes involve fixed jets in both the idle and high speed circuits. The idle restrictor jet can be removed for service but the idle restrictor cap (640053) must be re-installed to maintain compliance. All fixed jets that screw in seal against the taper, it is critical that you do not over tighten the jet when re-installing or damage to the metering hole will occur. Tighten to 5-8 inch lbs. (.5-1.0 NM) 11 www.mymowerparts.com For Discount Tecumseh Engine Parts Call 606-678-9623 or 606-561-4983 Peerless® Products News MST LEAKING AXLE SEALS Last year we advised you of the running change made to the axle seals used on all MST Series transaxles to improve sealing. We still hear about the occasional seal leakage on some MST’s. Our evaluations have found that when the unit was serviced and then reassembled the old seals were re-used with sealant placed around the perimeter of the seal. This sealant will get into the seal spring, harden and cause it to not function properly and leak. Always replace the seals if the transmission is serviced and DO NOT use sealant in the seal pockets. When re-assembly is complete we recommend a low pressure leak down testing of the unit. The test pressure must not exceed 15 PSI (1 Bar) or seal damage will occur. We have developed a test kit part number 670345 as an add on for an existing leak down tester or our complete kit 670340. Both are available from your normal supplier. NEW MST SERVICE VIDEO 696250 We have released the latest video in our series to help technicians understand the new MST transaxles. This video covers complete disassembly and re-assembly with tips such as not blocking the oil galley to the axles and proper assembly of both “A” and “B” inputs. This video and others available at $15.00 each (US price) are a great way to increase your knowledge or help a new technician you may have recently hired. Other videos available are: Ignition Systems - 695059 800 Series-Transaxle - 695285 Carburetor Troubleshooting - 695015 900 Series-Transaxle - 695148 Electrical Systems - 695185 820 SERIES SEALANT The 820 series transaxle has been changed from Loctite 515 Gasket Eliminator to Loctite Ultra Gray RTV Silicone, Tecumseh Part Number 788093A. This change improves the perimeter seal reducing the chance of water entering the case during cleaning by the operator. When service is needed on older models, please re-seal the case using the Loctite Ultra Gray RTV which is resistant to oil and grease. 12 www.mymowerparts.com For Discount Tecumseh Engine Parts Call 606-678-9623 or 606-561-4983 NEW VST SERIES PULLER The directional control arm on the VST205 hydrostatic series transaxle is attached using a tapered shaft or taper and key combination and then secured with a nut and lock washer. Should this arm need to be removed, a puller is required. Removal without using a puller can severely damage the internal parts of the transaxle, which is not repairable, causing replacement of the entire assembly. We have developed a special puller, Tecumseh Part Number 670342 to remove this arm. When the control arm is re-installed on the unit, it must be tightened in the neutral position, the nut is torqued to 25 to 30 ft. lbs. (33.9 - 40.7 Nm). Should you still have questions consult the 691218 Motion Drives Technician's Handbook. 670342 1310 SERIES AXLES 1 1/8 At the request of the Toro Company, we have increased the axle diameter of their 1310 series unit to 1-1/8 inches. This diameter change increases the durability of this model for their application. Service replacements for this model have been upgraded to this new axle diameter as well. NEW EXTERNAL SNUBBER FORCE ADJUSTMENT BULLETIN 308 REMOVE ACCESS PLUG WRENCH We have issued Service Bulletin 308 to review a change made to the “C” versions of the VST series transaxle (example VST205-024C) This bulletin outlines the adjustment of the shift force required to move the control lever. Never automatically assume the hydro is the problem, our evaluations of several units returned found no defect at all. In these situations we found a slipping belt (extremely glazed) from low tension to be the problem. COOLING FAN The bulletin outlines first cleaning the unit then the procedure for removing an access plug and adjusting the snubber screw which controls the shifting forces. You should NEVER need to turn the screw more than one turn. If you turn beyond this limit, the screw could come out of the case, this screw cannot be re-installed in the field and will require complete unit replacement. Please use extreme caution if performing this procedure and follow the bulletin exactly.

The width is being nearly doubled from .040 (1 mm) to .078 (2 mm). This can be done on the LEV engine because of the unique design of the valve seats and cylinder block. This design helps remove heat from the valve seat area by distributing it into the cylinder block and then dissipating it in its flow through design. This is also being done in conjunction with the use of heavier valve springs. The combination of the two may also help eliminate the light to no load popping that sometimes occurs when engines are running at low speeds. OLD NEW WIDER (.078 SEAT) (2 mm) CLIMATE GUARD™ OHH Although it was introduced last year, it now has a title, “Climate Guard™”. The official name for the air filter system used on emissions engines that are run in both warm and cold weather environments. This system has a baffle, that when placed in the winter position blocks cold air from the blower housing. Warmer air is then drawn through the air filter backing plate, this warmer air prevents the possible icing of the breather tube inlet to the carburetor. The icing is caused by crankcase vapor/condensation from the breather system required on emissions engines. When placed in the summer position it allows the cooling air from the blower housing to function normally, maximizing air filter life through our Kleen Aire® system. EMISSIONS INTEGRITY Just a reminder to you and your customer that it is required to maintain EPA and CARB compliance to use “as built” factory original or approved parts. This means parts used in, fuel metering systems, air induction systems, ignition systems, exhaust systems and crankcase breather systems must be Genuine Original Tecumseh factory parts or their equivalent. Ask your distributor about the Real Ones Parts program to prevent any possibility of violating compliance regulations by using less than OEM quality after market parts. 14 www.mymowerparts.com For Discount Tecumseh Engine Parts Call 606-678-9623 or 606-561-4983 FUEL CAP TETHER The fuel cap tether has made a come back in recent years especially on recreational vehicles. This cap tether may come in handy for the customer that has lost their fuel cap while mowing or forgot to put it on. The part number is 35480 and can be retrofitted to most newer style fuel caps with the standard 1.750 (44.45 mm) opening. 35480 EMISSIONS SERVICE BULLETINS A new series of bulletins have been earmarked to deal specifically with emissions related concerns. These bulletins will be designated by the “500” series classification. The headings listed on these bulletins will include, Date Issued; Engine Model Concerned, Family; and D.O.M. (Date Of Manufacture) affected. The body of the bulletin will contain information concerning; Potential Emission Control System Problem; Affected Specifications Numbers; and Warranty Inspection and Repair Procedure. BULLETIN 501 Some LEV 115 engines built between date codes 8091 through 8166 have the incorrect bowl nut in the carburetor. The suspect units will have the bowl nut on the carburetor stamped with the number 174. This jet should be replaced with part number 640087 which will have the number 169 stamped on it. There are 30 different specifications involved. Check the bulletin to determine if any units you may work on qualify. BULLETIN 501 BULLETIN 502 The following three model and spec numbers H3545690Z, H35-45726Z, and H40-55701A with D.O.M s of 8079 through 8201 have been built with the incorrect carburetor. You will need to locate and identify the manufacturing number on the carburetor mounting flange. If the number on the flange is stamped with the number 5161 the unit has already been changed and no repair is necessary. If the number is 5015 you need to replace it by ordering part number 640172. This carburetor will have the manufacturing number 5161 stamped on the flange. BULLETIN 502 15 www.mymowerparts.com For Discount Tecumseh Engine Parts Call 606-678-9623 or 606-561-4983 HEAD GASKETS ARE BACK WITH SHORT BLOCKS Back in 1994 we removed the head gaskets from short blocks. This was done because of thickness differences between the gaskets used on older engines versus newer product. The decision has been made to standardize on the thicker gaskets on most short blocks. This will have very little effect on engine power and will make the short block procedure much simpler. The exceptions will be the medium frame (HM and TVM) 8 and 10 hp engines which will include both gaskets and allow you to select dependent on its original gasket. This will be a running change as inventories are upgraded. MODEL NUMBER STANDARDIZATION An effort is being made to standardize on the model number designations used on lightweight vertical shaft engines. In the past this designation has bounced back and forth from horse power to cubic inch displacement. Three more models have been brought into the cubic inch displacement group. The VLV and OVRM series engines are adding a VLV 126 (12.6 C.I./206.5cc) an OVRM 105 (10.5 C.I./172cc) and a OVRM120 (12 C.I./ 196.7cc). Previous designations used in these Models will not be affected. VLV 126 (12.6 C.I./206.5cc) OVRM 105 (10.5 C.I./172cc) OVRM120 (12 C.I./196.7cc) TC SERIES CARBURETOR SPACER BLOCK We repeatedly receive calls from technicians regarding TC series engines not starting after servicing of the carburetor. During these evaluations we usually find one of two things have occurred. The first is an incorrectly installed insulator block causing the vacuum passage to not be aligned with the carburetor. The correct position is to have the impulse hole located in the spacer block facing toward the spark plug end. The transfer passage in the spacer block has to face toward the cylinder. The second is sealant or adhesive blocking the passage from previous improper service. Always check that these passages are open and use new gaskets during service, no sealant or adhesive is needed. TOWARD PLUG 16 www.mymowerparts.com For Discount Tecumseh Engine Parts Call 606-678-9623 or 606-561-4983 TC EMISSION CARBURETORS The TC series carburetor has been changed to meet emission standards for E.P.A. hand-held equipment. This upgrade has been made to all service inventory for previously built product as well. When you order a new carburetor, you will receive instructions explaining how to optimize the carburetor settings and install tamperproof caps. TAMPER CAPS PROPER TRANSAXLE WARRANTY INFORMATION BULLETIN 124 We have been evaluating transaxle warranty claims which we have returned to service dealers for lack of proper information. This evaluation has shown some improvements could be made to our identification tag. We have published and sent all manual holders Bulletin 124 explaining how to locate and read this information. This information reviews both older models and the improvements made to newer I.D. Tags. Tecumseh wants to reimburse our dealers promptly, however, we cannot without proper filing of the ESA-157R Claim form. Please supply the needed information when sending in claims. BULLETIN 124 IMPROVED GEAR PRODUCT IDENTIFICATION Beginning this March of 1999 Tecumseh is implementing a pilot warranty return program through selected CWD’s. This new procedure will return warranty claims not containing the needed information through your distributor rather than directly to you. Your distributor will work with you to obtain the needed information and answer any questions, then re-submit the claim signed by the distributor representative for prompt payment. PROPER SHIFT COLLAR INSTALLATION We regularly receive calls from technicians regarding proper installation of the shifting key collar on transaxles. The following tips should help you during servicing: Shift collars will generally have one of several variations. If the collar has an offset on one side, the thicker side must face in toward the tips of the shift keys. If the collar has no offset, check to see if there is a recess on the inside diameter. If there is, the recess must face toward the inside. A combination of offset and recess always has both facing in. INSIDE RECESS 17 www.mymowerparts.com For Discount Tecumseh Engine Parts Call 606-678-9623 or 606-561-4983 VST DIAGNOSTIC PROCEDURE The information on the following pages has been provided to help understand the internal operation of the VST. Do not use this information to attempt any internal repairs. Tecumseh's current policy on hydrostatic transaxles that have internal failures is to replace the complete unit. This has not changed. However, Tecumseh would like to provide a failure checklist to assist in making an accurate evaluation of the complete tractor to eliminate any unnecessary replacements. Here is a list of items to check and corrective actions to take. To properly test the unit for power loss. 1. Allow the unit to cool before trying the following steps. 2. Put the shift lever in a position that is 1/2 of the travel distance from neutral to forward. 3. Place the tractor on a 17 degree grade. 4. Drive the tractor up the grade (without the mower deck engaged). The loss of power experienced should be approximately 20%. This is considered normal. If the loss of power is approximately 50%, this would be considered excessive. 5. Bring the unit to neutral, shift into forward and note the response. Care should be taken to move the lever slowly to avoid an abrupt wheel lift. To determine if the problem is with the hydro unit, all external problem possibilities must be eliminated. Here are some potential problem areas. 1. Overheating: Heat can cause a breakdown in the viscosity of the oil which reduces the pressure used to move the motor. Remove any grass, debris, or dirt buildup on the transaxle cover and / or between the cooling fins and fan. Buildup of material will reduce the cooling efficiency. 2. Belt slippage: A belt that is worn, stretched, or the wrong belt (too large or wide) can cause belt slippage. This condition may have the same loss of power symptom as overheating. Typically, the unit which has a slipping belt will exhibit a pulsating type motion of the mower. This can be verified visually by watching the belt and pulley relationship. If the belt is slipping, the belt will chatter or jump on the pulley. If the belt is good, a smooth rotation will be seen. Replace the belt and inspect the pulley for damage. 3. Leakage: The VST and 1800 Series have two oil reservoirs which can be checked for diagnostic purposes. The first is the pump and motor expansion bellows, With a small diameter blunt or round nose probe, check the bellows depth through the center vent hole. Proper depth from the edge of that hole is 3-1/4 - 3-1/2 inches (8.25 - 8.9 cm). The second chamber is for the output gears including the differential. FIRST make sure the tractor is level, then remove the drain/fill plug. NOTE: Some units that do not have differential disconnect will have two plugs. We recommend using only the primary plug. With a small pocket rule insert until you touch bottom of case. You can then remove it and check for 1/4 - 3/8 inches (6.5 - 9.5 mm) contact this is full at its 8 oz. capacity. 4. Low ground speed: If the linkage is not synchronized to absolute neutral, or the shift lever is not properly fastened to the tapered control shaft, full forward travel may not be achieved. This may cause a false reading and be misdiagnosed as a low power condition. This also could be caused by the brake not releasing. To determine absolute neutral, the hole in the tapered control shaft must face straight up and down, at this point make sure the OEM linkage is in neutral. To properly fasten the control lever to the shaft, torque the nut to 25-35 ft. lbs. (34 - 48.3 NM) of torque with the shaft and the lever in neutral. When attaching the shifter arm to the shaft you must prevent any rotation during torquing. This can be done by placing a long 5/16 bolt in the hole as shown in Illustration. Hold the bolt until the tapers are locked and the nut torque is correct. To make sure that the brake is not binding, drive the unit up a slight grade. Position the speed control lever into neutral. The unit should coast backwards. If the unit does not coast back slowly, the brake is not released from the brake disk. Adjust the brake linkage to release the brake completely when the foot pedal is released. 5. Hard to shift: Typically hard to shift symptoms are not caused by the hydrostatic unit. The shift arm should move with relative ease. Approximately 40-50 inch lbs. (4.48 - 5.6 NM) at the transaxle for foot pedal units or 150-200 inch lbs. (16.8 - 22.4 NM) for hand operated units. This varies depending on the type of linkage. Binding may occur in the linkage connections due to rust or moisture. Lubricating these connections and checking for bent or damaged parts should resolve hard shifting. 18 www.mymowerparts.com For Discount Tecumseh Engine Parts Call 606-678-9623 or 606-561-4983 PRODUCT CONTAINS PATENTED FEATURES 90o 90o from case/cover parting line is neutral Parting Line DIRECTION CONTROL SHAFT DIRECTION CONTROL LEVER POCKET RULE FOR OIL CHECK PUSH NUT SQUARE CUT "O" RING 3/8 1/4 DIFFERENTIAL DISCONNECT HOOKUP 90o 8.2 3¼" 3½" EXPANSION BELLOW'S CHECK COLD FOR CORRECT DEPTH NOTE: The above illustration is of a foot control unit with differential disconnect.

The evaluation of these units has revealed some poor sealing idle mixing chamber welch plugs. After first checking the fuel condition, air filter and spark plug, the engine still exhibits one of these conditions. We suggest that while the engine is running you spray the welch plug area with spray carburetor cleaner. If the run quality changes it would indicate a leak around the welch plug requiring repair. Completely clean the welch plug area, then re-seal the plug using fingernail polish which should eliminate the problem. If the run condition does not change when you spray the welch plug area, further inspection will be needed. WELCH PLUG LEV ENGINES MIS-FIRING FIXED LINE TRIMMERS We have been evaluating field comments regarding LEV engines popping or mis-firing out of the muffler. These particular models of LEV are used on the new fixed line trimmer applications equipped with a remote throttle stop in the control. We have found some production models where the ignition ground tab on the throttle control plate was positioned very close to the blower housing causing intermittent grounding. Should you encounter this condition remove the extra blade from the wire terminal as shown. This is done using a side cutter to trim the extra blade away. This procedure may require the removing of the blower housing to access the speed control. HH AND OH CAST IRON CRANKSHAFT AND CAM GEARS In an effort to keep parts available for the OH and HH cast iron series engines, we have decided to obsolete the straight cut gears and will make available only crankshafts with helical cut gears. When using this crankshaft to repair older cast-iron units equipped with straight cut crankshaft, camshafts and governor gears, it will be necessary to order new helical cut camshaft and governor gears to match tha crankshaft. When repairing the OH Cast Iron series engine you will need a 34751 helical governor gear and 34752 helical camshaft gear. If you are repairing a HH Series engine, order 34691 helical governor gear and 34692 helical camshaft gear. 20 www.mymowerparts.com For Discount Tecumseh Engine Parts Call 606-678-9623 or 606-561-4983 TC AIR GAP REMINDER We occasionally hear complaints of poor or hard starting TC engines used on post hole diggers, ice augers and cultivator tillers. In addition to the normal checks for fresh fuel, good spark plug and a clean filter, check the CDI ignition module air gap. The TC series uses two different settings dependent on application and model which effect proper ignition timing. All TC200 and 300 rotary mowers applications use a .0125 gap (.317 mm), gap tool 670297. All other TC300 models use a gap of .030 (.762 mm), gap tool 670321. 21 www.mymowerparts.com For Discount Tecumseh Engine Parts Call 606-678-9623 or 606-561-4983 Miscellaneous Product News SNOW PRODUCTS STARTS There are times when dealers are confronted with customers who purchase snow equipment when the ambient temperature is above 50° F (10°C) The starting procedures at these temperatures should not require priming the engine. Therefore we have included the number of primes needed to start the engine at different temperature ranges in the operators manual. This will possibly prevent the over priming and flooding of engines at warmer temperatures, and eliminate this situation. The guidelines are as follows. With the choke on and temperatures below 15° F (-9°C) three primes, 15° F (-9°C) to 50° F (10°C) one prime, and above 50° F (10°C) zero primes choke only. NEW SMART START PACKAGING This product has been extremely popular in its inaugural year and has established itself firmly in the market place. This was done primarily through the counter display part number 730255. This fuel stabilizer is now available in a three packet bubble pack display part number 740063. This product has made fuel stabilization so easy that many consumers and shop owners use it year round, not just for off season storage. Just one packet stabilizes up to 21/2 gallons (10 Litres) of fresh fuel. This dry type stabilizer dissolves rapidly and does not create a mess or stain like many liquid varieties and requires no complicated mixing formulas. 22 www.mymowerparts.com For Discount Tecumseh Engine Parts Call 606-678-9623 or 606-561-4983 VST REPLACEMENT PROGRAM BULLETIN 307 We have again reviewed the issue of possible field service of the VST series transaxle. We have decided that Bulletin 307 must stay in effect for an indefinite period of time in the United States only. We would like to review some of the key issues that are driving this decision. The VST series transaxles used in this program are manufactured using the following stringent program: BULLETIN 307 1. Initial review of your warranty claim filed with the unit describing the condition. 2. Complete disassembly, cleaning and inspection of all components. 3. Replacement of any parts not meeting original manufacturing specifications. 4. Reassembly in a clean room environment (dust and dirt free) to original new specifications. Re-filling the pump and motor side with a special synthetic oil used in the aviation industry. All air is the removed through a bleeding off process. 5. After re-assembly the unit is pressure tested insuring unit integrity. 6. We then load test the unit checking axle output torque and speed on a special test machine to assure the customer of trouble-free operation. This test bench alone would cost a service center $20,000 US dollars to duplicate, adding to the complexity of field service. MICROFICHE UPDATES During the past several months we have increased the number of Microfiche cards per mailing in an effort to keep your data as current as possible. During 1998 you should have received the following card numbers 1, 3A, 3B, 8A, 8F, 9B, 10C, 12A-1, 12B, 16B, 16C, 18B, 18B-1,18B-2, 24, 24A, 27A, 30, 31, 33, 35, 35A and 35b. We have also sent out an up to date paper version of the index card dated 8/98 with the mechanic’s mailing which began in December of 1998. Please use this card to verify that your microfiche is current, should you have any damaged or missing cards please send us a written request only for the needed replacements.

BULLETIN 123 BULLETIN 123 With the implementation of emissionized engines, we were required to change the engine identification system we used. This new system has caused many warranty claims to be rejected for a lack of proper information. We have published Bulletin 123 to help you understand the needed information. Please make sure you supply the information so we can reimburse you promptly. ACCURATE WARRANTY CLAIM INFORMATION Beginning this March of 1999 Tecumseh is implementing a pilot warranty return program through selected CWD’s. This new procedure will return warranty claims not containing the needed information through your distributor rather than directly to you. Your distributor will work with you to obtain the needed information and answer any questions, then re-submit the claim signed by the distributor representative for prompt payment. QUICK FIX CARB KIT This kit was released late this year and we want to remind you of its availability. The part number is 632760 and can be ordered from your normal supplier. This one kit now replaces several previous kits and has been upgraded to include the idle restrictor cap. Please remember this kit does not service the series “7” or the Vector (VLV) non metallic bowl carburetors. When you service a carburetor, please order this kit and always remove and clean all Welch plug cavities before replacing them. TAMPER CAP 24 www.mymowerparts.com For Discount Tecumseh Engine Parts Call 606-678-9623 or 606-561-4983 NO METHANOL BULLETIN 108 We have added a caution to our Owner’s Manual regarding a zero tolerance level for any methanol blended fuel or additives. We have reviewed some carburetors returned from service and found the damage to have occurred from methanol based fuel and or fuel dryers. Should the customer feel they need a fuel dryer in their snow product use only isopropyl based dryers at the correct ratio to prevent freeze up. Remember if a little is good a lot is NOT better. FUEL ADDITIVES Only fuel additives such as Tecumseh's fuel stabilizer Smart Start™ part number 730245 or liquid varieties can be used when mixed properly. For winter applications, Isopropyl alcohol fuel dryers may be used in the fuel system but must be mixed at the proper ratio recommended by the manufacturer. NEVER USE METHANOL BASED DRYERS. STARTER CLIP BULLETIN 122 In Spring of 1998 we issued this Bulletin 122 regarding starters not engaging principally on rotary mower product. We recently re-sent this to all manual holders. Should you encounter one of these situations, please order part number 590760. This kit includes a replacement disc to prevent water migration into the starter. Then file an ESA-157R claims with us if warranty applies. BULLETIN 122 RECOIL STARTER WILL NOT ENGAGE WHEN PULLED 25 www.mymowerparts.com For Discount Tecumseh Engine Parts Call 606-678-9623 or 606-561-4983 Europa News REVISED SOFT PULL STARTER From production starting September 1998, a revised soft pull starter will be used. Although the design is very similar to existing product, improvements have been made to the housing, the pulley material, design, and the pawls. These improvements have been aimed at improving the durability of the unit, and to improve the way in which the rope is held on the pulley. Individual spare parts for this starter will be made available, and the repair procedures are identical to the existing product which uses the roll pin to secure the pulley to the housing. STARTER REPAIR KIT Utilizing the parts used in the new soft pull starter, a repair kit will be made available to service existing soft pull starters. This kit, which is available under part number 16630041, will consist of pulley, recoil spring and retainer, pawls, pawl springs and retainer, together with new roll pin assembly. VALVE CLEARANCE CHECK Since July 1998 the valve clearance on Europa manufactured engines has been revised to the following: 4-cycle vertical shaft side valve (L’head) 0.15-0.25 mm (.006 - .010) 4-cycle horizontal shaft side valve (L’head) 0.10-0.20mm (.004 - .008) 4-cycle OHV engines(vertical & horizontal crankshaft) 0.050-0.15mm (.002 - .006) Valve clearances are now as shown above irrespective of the decompression system used. REVISE CAMSHAFT Over the past 12 months some engines have been equipped with a camshaft manufactured with plastic lobes as well as the plastic timing gear. These camshafts are interchangeable with the standard camshaft. Valve clearances should be set as listed above. 26 www.mymowerparts.com For Discount Tecumseh Engine Parts Call 606-678-9623 or 606-561-4983 ELECTRIC START ENGINES Electric start engines are now equipped with a flywheel that features a plastic ring gear in place of the aluminum ring gear that was cast as part of the flywheel. This is more robust than the original but also provides much quieter operation. It is however essential that the clearance between the flywheel ring gear and the starter pinion is set correctly. There should be a clearance of 1/16” (1.6 mm) between the tip of one tooth and the root of another. This can easily be checked using a sized piece of wire. It is essential to check this clearance when replacing a flywheel that has broken teeth, as it is possible that when the failure occurred, the starter mounting has become distorted, increasing the clearance. Failure to check this clearance will result in premature ring gear failure. 1/16" (1.6 mm) Between Flywheel and Starter INLET VALVE OIL SEAL Most premium engines are now equipped with an inlet valve oil seal which acts as a top valve spring retainer. This seal, which is part number 19610001, should be replaced whenever it has been removed from the valve stem. The correct installation is shown on the adjacent drawing. FLYWHEEL ATTACHMENT MV100S ENGINES Some MV100S engines utilize an adapter collar to locate them to the crankshaft as opposed to the standard flywheel key. The engine specification number will identify which system is used. When reinstalling the flywheel that utilizes this collar, it is necessary to press the collar into the flywheel taper flush to the inside hub before installing the flywheel to the crankshaft. The pressed ridge in the collar will align with the flywheel keyway. 27 www.mymowerparts.com For Discount Tecumseh Engine Parts Call 606-678-9623 or 606-561-4983 3 AMP CHARGING SYSTEM Some Futura 60 engines are now equipped with a 3 amp DC charging system to enable the use of an electric clutch. Should the charging be in doubt, it should be checked in the following way. 3 Amp D.C. Charging System Futura 60 1. Start the engine and let it run at high speed. 2. Disconnect the engine from the machine’s wiring loom by disconnecting the black multi connector. 3. Set the engine speed to 3000 rpm. 4. Check the DC voltage output by connecting a voltmeter between the red wire on the 4-way connector to earth. Minimum reading should be 9.5 volt DC. At this minimum reading the system is working correctly. 5: If this minimum reading is not achieved check the AC voltage output by pulling back the sheathing covering the diode and connecting the voltmeter (set on AC scale) between ground and output wire prior to the diode. The reading should be 22 volts AC at 3000 rpm. If this minimum reading is achieved the diode at fault must be replace. 6. If this minimum reading is not achieved than the alternator coils are at fault and require replacement. 7. Do not forget to reconnect the connector to the machine wiring harnes when repair has been completed. (If the machine still exhibits electrical problems and the charging system checks out OK, then the machine should be checked for a poor battery, poor connections, failed relays etc). ENGINE IDENTIFICATION Starting September 1997 all Tecumseh Europa engines were identified by an adhesive label affixed to the blower housing. The actual positioning of this label varies according to engine model. On vertical shaft engines it can usually be found on the oil filler side towards the spark plug. On horizontal shaft engines it can usually be found adjacent to the spark plug. A sample of this label is shown opposite. These labels are in addition to the existing information stamped on the crankcase. 28 www.mymowerparts.com For Discount Tecumseh Engine Parts Call 606-678-9623 or 606-561-4983 CATALYTIC CONVERTERS Many of our engines can now be specified with catalytic converter which takes the form of a tablet or wire mesh which is installed within the muffler. These mufflers can be identified by the word “KAT” pressed into them. As with automotive catalytic converters, it is necessary to follow certain ruler if the catalytic converter is to remain effective for a reasonable period. Obviously the customer must be advised only to use unleaded fuel. In addition they should be made aware that the engine should not be over-filled with oil, or tipped in a way to allow oil to flood into the combustion chamber (spark plug down). Catalytic equipped engines are only supplied with primer carburetors, but the customer should also be made aware of the danger of unnecessary over-priming of the engine. With a little care the catalytic converters will be effective for many seasons. CONNECTING ROD The connecting rod used in our European manufactured engines ranging from 3.7 - 5.5 HP has been modified in the following areas. 1.

Unleaded gasoline burns cleaner, extends engine life, and promotes good starting by reducing the build-up of combustion chamber deposits. Leaded gasoline, gasohol containing no more than 10% ethanol, premium gasoline, or unleaded gasoline containing no more than 15% MTBE (Methyl Tertiary Butyl Ether), 15% ETBE (Ethyl Tertiary Butyl Ether) or 10% ethanol, can be used if unleaded regular gasoline is not available. Reformulated gasoline that is now required in several areas of the United States is also acceptable. NEVER USE gasoline, fuel conditioners, additives or stabilzers containing methanol, gasohol containing more than 10% ethanol, unleaded regular gasoline containing more than 15% MTBE (Methyl Tertiary Butyl Ether), 15% ETBE (Ethyl Tertiary Butyl Ether) or 10% ethanol, gasoline additives, or white gas because engine/fuel system damage could result. See STORAGE instructions in Technicians Manual, Operators Manual, or Bulletin 111. For year round fuel stability in and out of season, use "Smart Start" part number 730245. FUEL ADDITIVES Only fuel additives such as Tecumseh's fuel stabilizer Smart Start part number 730245 or liquid varieties can be used when mixed properly. For winter applications, Isopropyl alcohol fuel dryers may be used in the fuel system but must be mixed at the proper ratio recommended by the manufacturer. NEVER USE METHANOL BASED DRYERS. OILS 2-CYCLE Tecumseh two cycle engines require the use of a NMMA TC-W3 or TC-WII certified oil. TECUMSEH RECOMMENDS USING TWO CYCLE OIL PART #730227, which is a premium blend that ensures cylinder wall lubrication, mixes easy, does not separate and is specially formulated for use in air or water cooled two cycle engines. The proper fuel mixture ratio of oil to gasoline for specific engines will be found in the owners operating instructions and on the decal attached to the blower housing or fuel tank of the engine. FOR NEW ENGINES: USE TWICE THE NORMAL OIL QUANTITY FOR THE FIRST GALLON OF FUEL ACCEPT ON TC SERIES WHERE THE STANDARD MIX RATIO IS SUFFICIENT. 4-CYCLE TECUMSEH FOUR CYCLE ENGINES REQUIRE THE USE OF A CLEAN, HIGH QUALITY DETERGENT OIL. Be sure original container is marked: A.P.I. service SF thru "SJ" or CD. TECUMSEH RECOMMENDS USING ONE OF THE FOLLOWING FOUR CYCLE OILS THAT ARE SPECIALLY FORMULATED TO TECUMSEH SPECIFICATIONS. DO NOT USE SAE10W40 OIL. FOR SUMMER (Above 320F) USE SAE30 OIL. PART #730225 (SAE10W30 is an acceptable substitute.) Use SAE30 oil in high temperature, high load applications. Using multigrade oil may increase oil consumption. FOR WINTER (Below 320F) USE SAE5W30 OIL. PART #730226 (SAE10W is an acceptable substitute.) (BELOW 00F ONLY): SAE0W30 is an acceptable substitute. NOTE: For severe, prolonged winter operation of HH120 model, SAE10W oil is recommended. 30 www.mymowerparts.com For Discount Tecumseh Engine Parts Call 606-678-9623 or 606-561-4983 SERVICE BULLETIN 110 INFORMATIONAL ISSUED: May 1985 REVISED: July 1997 SUBJECT: High Altitude Carburetor Kits for Fixed Main Carburetors Engines built to O.E.M. specifications may experience starting and operating problems when used in areas of the country where the altitude is four thousand feet above sea level or higher.

This repair will only affect starters that have the white plastic locking tab located in the top/center of the starter. The locking tab may be covered by a round protective decal or could be located in the recoil under a decorative cover. The decorative cover will have to be removed to allow for repair. However, it is not necessary to remove the recoil starter from the engine to make the repair. To make the repair you need to remove the protective decal to expose the white plastic locking tab. Use a small flatblade screwdriver or needlenose pliers to pry up on the tab and remove it from the starter. Discard the old tab and replace it with a new metal locking tab part #590760, which also includes a new protective decal. Press the new metal locking tab down into the retainer until it snaps into place. Place the new protective decal over the tab hole to prevent any water or debris from entering the starter. This procedure and paperwork should take approximately 15 minutes to complete. An ESA 157R warranty claim form should be filed through normal channels.

We ask that you help us by furnishing accurate and correct information in Box 5 and all the other Boxes on the claim form. Failure to help in this effort results in added expense and work for you and Tecumseh. It also results in delayed payments to you and that affects your receivables. Lastly, unless we can eliminate claims submitted with lack of accurate information we may consider having your Tecumseh source of supply receive your claims for editing prior to submitting claims to Tecumseh. 33 www.mymowerparts.com For Discount Tecumseh Engine Parts Call 606-678-9623 or 606-561-4983 SERVICE BULLETIN 124 INFORMATIONAL ISSUED: September 1998 SUBJECT: Improved Gear Product Identification MODELS OR TYPES AFFECTED: All Models The recent warranty audit referenced in bulletin number 123 suggested we review the way our new Tecumseh/Peerless® models are identified. That review found improvements where needed in the identification system to make them standard with the new emission regulations requirements covering engine product and the New ESA 157R Claim Form. As a result of this review, we have changed the product ID tag to make it easier to read. Should this data be needed for service or warranty situations these improvements will make locating the needed model and specification information easier. Example Numbers 1 and 2 below, show the present bar code labels currently being used. We have identified the important fields of information that is required for warranty claims. In addition, a new easier to read bar code label (No. 3 below) is being introduced on all units provided after October 1, 1998. Again we have highlighted the information you are required to supply.

After review of the complex issues of servicing this unit, we have decided on a unique approach for Tecumseh to handle IN WARRANTY servicing by complete replacement, if needed, with factory furnished units. These units may be Tecumseh re-manufactured units or new units at our discretion. Effective November 15, 1997, the following procedure is to be followed by all Authorized Tecumseh Service Centers if an Internal Failure occurs WITHIN THE WARRANTY PERIOD. We are enclosing the revised Warranty Policy reflecting this change. 1. Be sure you have reviewed the trouble shooting section of the Peerless® Technicians Handbook, No. 691218, to insure the problem is internal and not a linkage problem. All external components serviceable previously such as pulley, brakes, and levers are still serviceable as before. 2. If you have identified the trouble as internal, contact your distributor for replacement authorization under the normal warranty authorization procedure. 3. You will then need to look up the replacement transaxle using the attached list of replacements or the parts look up system you have chosen (i.e., microfiche, computer or paper). NOTE: Place an "R" on the end of the service replacement part number when ordering from your normal source. The unit will be shipped N/C with freight prepaid direct to your dealership. Example: Part #794667 (R). If your replacement model had an "A" suffix, change it to an "R" as referenced. 4. Ordering is done through your normal source of supply. DO NOT attempt to combine any "R" number with a regular order. Only the "R" will be shipped N/C Prepaid. Any added orders will be kicked out (not shipped). 5. You then file your DISTRIBUTOR AUTHORIZED, COMPLETELY FILLED OUT ESA157 warranty claim with us for the R&R of the transaxle. Upon receipt of the warranty claim in Grafton, Wisconsin, Tecumseh will issue a recall tag through UPS to pick up the unit for return to us. 6. When your claim is matched up with your returned transaxle, we will process it for prompt payment. 7. Before returning the defective transaxle, place a COPY of the ESA157 warranty claim in the original box, which should be used for return shipment of the transaxle. 8. This program will be in effect for the United States only. We appreciate your assistance in this warranty replacement procedure. 35 www.mymowerparts.com For Discount Tecumseh Engine Parts Call 606-678-9623 or 606-561-4983 SERVICE BULLETIN 308 PEERLESS ISSUED: December 1998 SUBJECT: Hydrostatic Transaxle Shift Force MODELS AFFECTED: VST205 We have made a change to the VST series transaxle cover. This allows for external adjustment if necessary, of the shift force required to move the control lever. This adjustment can be accomplished on all C series and later model units. To determine if this adjustment can be made on the unit in for repair, locate the ID tag as shown in the illustration below. When a C or newer unit is found, use the adjustment procedure as outlined below. Remember to disconnect and check the equipment linkage first, before performing this adjustment or replacing the transaxle on early production units. TO ADJUST MOTION CONTROL LEVER (See Insert) The motion control lever has been preset at the factory and adjustment should not be necessary. If for any reason the motion control lever will not hold its position while at a selected speed or is difficult to move, it may be adjusted as follows: Park tractor on a level surface. Stop tractor by turning key to the OFF position and engage parking brake. NOTE: The transmission should not be warm when making this adjustment. Allow it to cool to room temperature before making this adjustment. The plug may be accessible through the battery box area, however, each manufacturer may be different. REMOVE ACCESS PLUG WRENCH If access can be gained through the battery area, it will be necessary to remove the battery and the battery box from the tractor. The most extreme case may require transaxle removal from the frame. Raise the seat and open battery box door. Disconnect BLACK battery cable first, then the RED cable. Remove battery and battery box from tractor. COOLING FAN HOUSING POCKET VST - 205 - 003C MODEL D.O.M.

PEERLESS NOTE: When reinstalling battery box, ensure that battery acid drain tube is routed toward the rear and is clear of the cooling fan. Locate the access plug under the cooling fan. This plug and surrounding area must be cleaned to prevent contamination of internal parts during this procedure. Before removing the plug, pack a cloth in the housing pocket to absorb excess oil. Clean the bellows cover plate. Place a piece of masking tape over the hole located in the center of cover plate. This will prevent air from entering the bellows area when access plug is removed, and prevent oil from coming out access hole when plug is removed. Using a needle nose pliers, remove the access plug described above. When the plug is removed, a small, quantity of oil will flow out of the transaxle. This is normal and will not effect its function. Insert a #30 torx or 5/32 allen wrench into the access hole and locate the adjustment screw. Adjust the screw clockwise 1/4 turn at a time to increase motion control effort. NOTE: If for any reason the effort to move the motion control lever becomes too excessive, reverse the above procedure by turning the adjustment screw counterclockwise 1/4 turn. Clean the access plug and insert it into position using the torx or allen wrench. Clean spilled oil from transaxle and reinstall battery box and battery into tractor. When connecting battery be sure to connect the RED battery cable first. An effort of 150-200 in-lbs. of torque to move the transaxle motion control lever is required for hand control units and an effort of 40-50 in-lbs. of torque to move the transaxle motion control lever on foot control units. An effort of 15 - 18 lbs. at the motion control lever knob is normal. Road test tractor after adjustment and repeat procedure if necessary. NOTE: The neutral spring must be removed to check the force on foot pedal control units. 37 www.mymowerparts.com For Discount Tecumseh Engine Parts Call 606-678-9623 or 606-561-4983 SERVICE BULLETIN 406 4 CYCLE ISSUED: October 1998 SUBJECT: Smoking Out of Muffler on Initial Start Up MODELS AFFECTED: VLV 50 through 66 SERIAL NO'S AFFECTED: 7002 through 7128 We have received comments from the service system regarding instances of NEW VLV model engines exhibiting smoke from the muffler during initial engine operation. These instances of smoke from the muffler in a new engine may be caused by storage or shipment with the spark plug pointing down. BEFORE performing the procedure below please make sure the engine has been run for at least 30 minutes to burn out any oil residue inside the muffler. If the smoking continues after this time period proceed below. After investigation we have determined the cause of the smoking. This is the result of an irregular casting surface in the valve spring box, which does not allow proper seating of the seal allowing oil to pass. PROCEDURE: 1. Remove the muffler, cylinder head and valve box cover. 2. Remove the Intake valve spring, valve and seal. 3. Install the NEW valve stem seal part no. 40016A as shown (see illustration). 4. Replace the cylinder head gasket part no. 36061 and valve box cover gasket part no. 27234A. 5. Re-torque the cylinder head to 180-220 inch Lbs following the sequence below. 6. A kit containing all the above parts can be ordered under part no. 730617.

Tecumseh recommends the use of a high quality, brand name petroleum based oil in our engines. Very few air cooled engines have any type of oil filtration system, making regular oil changes critical to remove impurities from the engine and maximize engine life. Consult the operators or repair manual for the oil change interval and viscosity based on equipment operating temperature.

The proper type and ratio of two cycle oil is critical to long life and low maintenance of the engine. Tecumseh tests engines using NMMA (National Marine Manufacturers Association) certified oil such as Tecumseh part number 730227, but any NMMA certified two cycle oil will provide adequate lubrication for long life. The use of non certified oils and improper mix ratios can cause severe engine problems and possibly void warranty consideration if the damage was the result of poor lubrication. Our position regarding two cycle lubrication is simple, use only NMMA certified oil or Tecumseh two cycle oil mixed at our recommended ratio and your engine will be properly lubricated. Please do not recommend using anything else to your customer, this will avoid getting you caught in the middle, should problems occur. TECUMSEH 2-CYCLE ENGINES REQUIRE THE USE OF BIA, NMMA, TC-WII OR TC-W3 CERTIFIED OIL, NON-BIODEGRADABLE. NOTE: DOUBLE THE OIL QUANTITY FOR FIRST GALLON OF FUEL/OIL MIXTURE TO ASSIST BREAKIN. NOTE: FOR TC AND CRAFTSMAN ENGINES, DOUBLING OF THE MIX IS NOT REQUIRED. SEARS CRAFTSMAN TWO CYCLE OIL HAS BEEN TESTED AND APPROVED. ALL MODELS USE A 40:1 MIX RATIO ON ALL 2-CYCLE ENGINES EXCEPT TC'S WHICH USE A 24:1 TWO-CYCLE FUEL/OIL MIX RATIOS 24:1 AV520 Types 670 & 653 AV600 Type 600-10 & Up TC-TCH 200/300 MV100S 32:1 TVS600 All Types AH600 50:1 TVS / TVXL HSK840 - 850 HSK600 MIXES EASY DOES NOT SEPARATE PREMIUM BLEND FOR BOTH AIR AND WATER COOLED ENGINES ENSURES CYLINDER WALL LUBRICATION 2-CYCLE ENGINE OIL PART NO. 730227 TECUMSEH 2-CYCLE ENGINE OIL may be used in a variety of 2 cycle engines including: outboards, lawnmowers, snowthrowers, string trimmers, and edgers at any fuel/oil mixing ratio up to 50:1.
