IS
YOUR ENGINE READY
TO
GO?
For your safety, and to maximize the service life of your equipment,
it
is very important to take a few moments before you operate the
engine to check its condition. Be sure to take care of any problem you
find, or have your servicing dealer correct
it,
before you operate the
engine.
Improperly maintaining this engine,
or failing to correct a problem
before operation, could cause a
malfunction
in
which you could be
seriously injured.
Always perform
a
preoperation
inspection before each operation,
and correct any problem.
Before beginning your preoperation checks, be sure the engine is level
and
the engine switch is
in
the OFF position.
Check the General Condition
of
the Engine
Look around and underneath the engine for signs of oil, gasoline,
or
coolant leaks.
Remove
any
excessive dirt or debris, especially around the muffler.
Look for signs of damage.
Check that all shields and covers are in place, and all nuts, bolts, and
screws are tightened.
13
BEFORE
OPERATION
Check the Engine
Check the engine oil level (see page
25).
The engine protection
system
will
automatically stop the engine before the oil level falls
below safe limits. However, to avoid the inconvenience of an
unexpected shutdown, always check the engine oil level before
startup.
Check the coolant level
in
the reserve tank (see page
34).
It
should be
between the MAX and MIN marks when the engine is at normal
operating temperature.
Check the radiator screen (see page
32),
and clean
it
if blocked
with
dirt
and debris.
Check the
air
filter (see page
29).
A dirty air filter
will
restrict air flow
to
the carburetor, reducing
engine performance.
Check the fuel level. Starting
with
a full fuel tank
will
help to
eliminate or reduce operating interruptions for refueling.
Check the Equipment Powered
by
This Engine
Review the instructions provided with the equipment powered by this
engine for any precautions and procedures that should be followed
before engine startup.
14
SAFE OPERATING PRECAUTIONS

unconsciousness and even kill you.
Avoid any areas
or
actions that
expose you to carbon monoxide.
Review the instructions provided with the equipment powered by this
engine for any safety precautions that should be observed
in
conjunction
with
engine startup, shutdown, or operation.

THE IMPORTANCE
OF
MAINTENANCE
Good maintenance
is
essential for safe, economical, and trouble-free
operation.
It
will
also help reduce air pollution.
Improperly maintaining this engine,
or failure to correct
a
problem
before operation, can cause a
malfunction
in
which you can be
seriously hurt or killed.
Always follow the inspection and
maintenance recommendations and
schedules
in
this owner's manual.
To help you properly care for your engine, the following pages include
a
maintenance schedule, routine inspection procedures, and simple
maintenance procedures using basic
hand
tools. Other service tasks
that
are more difficult, or require special tools, are best handled by
professionals and are normally performed by a Honda technician or
other qualified mechanic.
The maintenance schedule applies to normal operating conditions. If
you operate your engine under unusual conditions, such as sustained
high-load or high-temperature operation, or use in unusually wet or
dusty conditions, consult your servicing dealer for recommendations
applicable to your individual needs and use.
Maintenance, replacement or repair of emission control devices and
systems may be done by any engine repair establishment
or
individual, using parts that are "certified" to EPA standards.

SERVICING YOUR HONDA ENGINE
MAINTENANCE SAFETY
Some of the most important safety precautions follow. However, we
cannot warn you of every conceivable hazard that can arise
in
performing maintenance. Only you can decide whether or not you
should perform a given task.
Failure to properly follow
maintenance instructions and
~
precautions can cause you to be
'
seriously hurt or killed.
Always follow
the
procedures and
precautions
in
the owner's manual.
Safety Precautions
Make sure the engine is off before you begin any maintenance or
repairs. This
will
eliminate several potential hazards:
-Carbon monoxide poisoning from engine exhaust.
Be sure there is adequate ventilation whenever you operate the
engine.
Let the engine and exhaust system cool before touching.
Do
not run the engine unless instructed to do
so.
-Burns from hot parts.
-Injury from moving parts.
Read the instructions before you begin, and make sure you have the
tools and skills required.
To
reduce the possibility of fire or explosion, be careful when
working around gasoline. Use only a nonflammable solvent, not
gasoline,
to
clean parts. Keep cigarettes, sparks and flames away
from all fuel-related parts.
Remember
that
your servicing dealer knows your engine best and is
fully equipped to maintain and repair
it.
To
ensure the best quality and reliability, use only new, genuine
Honda parts or their equivalents for repair and replacement.

FUEL RECOMMENDATIONS
Use unleaded gasoline with a pump octane rating
of
86
or higher.
These engines are certified to operate on unleaded gasoline. Unleaded
gasoline produces fewer engine and spark plug deposits and extends
exhaust system life.
Never use stale or contaminated gasoline or an oil/gasoline mixture.
Avoid getting dirt or water in the fuel tank.
Occasionally you may hear a light ”spark knock” or “pinging”
(metallic rapping noise) while operating under heavy loads. This is no
cause for concern.
If spark knock or pinging occurs at a steady engine speed, under
normal load, change brands of gasoline. If spark knock or pinging
persists, see an authorized Honda servicing dealer.
Running the engine with persistent spark knock or pinging can cause
engine damage.
Running the engine
with
persistent spark knock or pinging is misuse,
and the
Distributor‘s Limited Warrantydoes
not cover parts damaged
by misuse.

STORING
YOUR
ENGINE
Storage Preparation
Proper storage preparation is essential for keeping your engine
troublefree
and
looking good. The following steps
will
help to keep
rust and corrosion from impairing your engine's function and
appearance, and
will
make the engine to start easier when you use
it
again.
Cleaning
If the engine has been running, allow
it
to cool for
at
least half an hour
before cleaning. Clean all exterior surfaces, touch up any damaged
paint, and coat other areas that may rust
with
a light film of oil.
m
Using
a
garden hose or pressure washing equipment can force
water into the air cleaner or muffler opening. Water in the air cleaner
will
soak
the air filter, and water that passes through the air filter or
muffler can enter the cylinder, causing damage.
Water contacting a hot engine can cause damage. If the engine has
been running, allow it to cool for at least half an hour before
washing.
Fuel
Gasoline
will
oxidize and deteriorate in storage. Old gasoline
will
cause hard starting, and
it
leaves gum deposits that clog the fuel
system. If the gasoline in your engine deteriorates during storage, you
may need to have the carburetor and other fuel system components
serviced or replaced.
The length of time that gasoline can be left
in
your fuel tank and
carburetor without causing functional problems
will
vary with such
'
factors as gasoline blend, your storage temperatures, and whether the
fuel tank is partially or completely filled. The air in a partially filled fuel
tank promotes fuel deterioration. Very warm storage/temperatures
accelerate fuel deterioration. Fuel deterioration problems may occur
within a few months, or even less if the gasoline was not fresh when
you filled the fuel tank.
HELPFUL
TIPS
&
SUGGESTIONS
The
Distributor's Limited Warranty
does not cover fuel system
damage or engine performance problems resulting from neglected
storage preparation.
You can extend fuel storage life by adding a fuel stabilizer that is
formulated for that purpose, or you can avoid fuel deterioration
problems by draining the fuel tank and carburetor.
ADDING A FUEL STABILIZER TO EXTEND FUEL STORAGE LIFE
'
When adding a fuel stabilizer, fill the fuel tank
with
fresh gasoline. If
only partially filled, air in the tank
will
promote fuel deterioration
during storage. If you keep a container of gasoline for refueling, be
sure
that
it
contains only fresh gasoline.
1.
Add fuel stabilizer following the manufacturer's instructions.
2.
After adding a fuel stabilizer, run the engine outdoors for
10
minutes
to
be
sure that treated gasoline has replaced the untreated gosoline
in the carburetor.
3.
Stop
the
engine, and if the fuel tank is equipped with
a

DRAINING THE FUEL TANK AND CARBURETOR
1.
Disconnect the fuel line to the engine, and drain the fuel tank into an
approved gasoline container. If the fuel tank is equipped
with
a
valve,
turn the fuel valve to the
OPEN
or
ON
position to enable draining.
After draining is completed, reconnect the fuel line.
2.
Loosen the carburetor drain screw, and drain the carburetor into an
approved gasoline container. After draining is completed, tighten
the carburetor drain screw.

4.
Crank the engine serveral revolutions to distribute the oil.
5.
Reinstall the spark plugs.
Storage Precautions
If your engine
will
be stored with gasoline in the fuel tank and
carburetor,
it
is important to reduce the hazard of gasoline vapor
ignition. Select a well-ventilated storage area away from any appliance
that operates with a flame, such as a furnace, water heater, or clothes
dryer.
Also
avoid any area
with
a
spark-producing electric motor, or
where power tools are operated.
If possible, avoid storage areas
with
high humidity, because that
promotes rust and corrosion.
Unless
all
fuel has been drained from the fuel tank, leave the fuel valve
lever in the
OFF
position to reduce the possibility of fuel leakage.
45
HELPFUL TIPS
&
SUGGESTIONS
Position the equipment
so
the engine is level. Tilting can cause fuel or
oil leakage.
With the engine and exhaust system cool, cover the engine to keep out
dust.
A
hot engine and exhaust system can ignite or melt some
materials.
Do
not use sheet plastic as a dust cover.
A
nonporous cover
will
trap moisture around the engine, promoting rust and corrosion.
Remove the battery and store
it
in a cool, dry place. Recharge the
battery once a month while the engine is
in
storage. This will help to
extend the service life of the battery.
Removal From Storage
Check your engine as described
in
the BEFORE OPERATIONchapter of
this manual.
If the fuel was drained during storage preparation,
fill
the tank with
fresh gasoline. If you keep
a
container of gasoline for refueling,
be
sure that
it
contains only fresh gasoline. Gasoline oxidizes and
deteriorates over time, causing hard starting.
If the cylinders were coated with oil during storage preparation, the
engine may smoke briefly at startup. This is normal.

Carburetor Modification for High Altitude Operation
At high altitude, the standard carburetor air-fuel mixture
will
be too
rich. Performance
will
decrease, and fuel consumption will increase. A
very rich mixture
will
also foul the spark plugs and cause hard starting.
Operation at an altitude that differs from that at which this engine was
certified, for extended periods of time, may increase emissions.
High altitude performance can be improved
by
specific modifications
to the carburetor. If you always operate your engine at altitudes above
5,000
feet (1,500 meters), have your servicing dealer perform this
carburetor modification. This engine, when operated
at
high altitude
with the carburetor modifications for high altitude use, will meet each
emission standard throughout its useful life.
Even with carburetor modification, engine horsepower
will
decrease
about
3.5%
for each 1,000-foot (300-meter) increase in altitude. The
effect of altitude on horsepower
will
be greater than this if no
carburetor modification is made.
I
NOTICE

When the carburetor has been modified for high altitude operation,
the air-fuel mixture will be too lean for low altitude use. Operation at
altitudes below
5,000

may cause the engine to overheat and result in serious engine damage.
For use at low altitudes, have your servicing dealer return the

If you use an oxygenated fuel, be sure
it
is unleaded and meets the
minimum octane rating requirement.
Before using an oxygenated fuel,
try
to confirm the fuel’s contents.
Some states/provinces require this information to be posted on the

The following are the
EPA
approved percentages of oxygenates:
ETHANOL
-
(ethyl or grain alcohol)
10%

METHANOL
-(methyl or wood alcohol) 5%
by
volume
You may use gasoline containing up to 5% methanol
by volume, as long as
it
also contains cosolvents and
corrosion inhibitors to protect the fuel system.
Gasoline containing more than 5% methanol
