This unit is equipped with a diaphragm-type
carburetor that has been carefully calibrated at
the factory. In most cases, no furtheradjustment
is requirad.
NOTE: To meet the 1995-1998 California
emission regulations, the carburetor
has adjustment needle trotter caps to
restrictthe amount of adjustment.
Removal or alterationof these caps
will voidthe unit's warranty.
Old or improperlymixed fuel are usually the
main reasons for the unit not runningpmpedy.
Drain and refillthe tank with fresh prepedy
mixed fuel pdor to making any adjustments,
Refer to OI1 and Fuel Informalion,

Rg. 22

The conditionof the air filter is important to the
operation of the unit, A dirty air filter will restrict
the air flow, which upsets the fuel-air mixture in

the carburetor. The resulting symptoms are often
mistaken for an out-of-adjustment carburetor.
Therefore, check the condition of the air filter
before adjusting the carburetor. Refer to Air
Rlter Maintenance.
