CARBURETOR
ADJUSTMENT
Carburetor adjustment
is critical and if
done improperly can permanently
damage the engine as well as the car-
buretor. If you require further assis-
tance or are unsure about performing
this procedure, call our customer as-
sistance help line at 1-800-235-5878.
Old fuel, a dirty air filter, a dirty fuel fil-
ter, or flooding may give the impres-
sion of an improperly adjusted carbu-
retor. Check these conditions before
adjusting the carburetor.
The carburetor
has been carefully set
at the factory. Adjustments
may be
necessary if you notice any of the fol-
lowing conditions:
• Engine will not idle. See LOW SPEED
MIXTURE ADJUSTMENT (L) under ad-
justing procedure.
• Engine dies or hesitates instead of ac-
celerating. See ACCELERATIONCHECK
under adjusting procedure.
• Loss of power. See MIXTURE ADJUST-
MENT (L or H) under adjusting proce-
dure.
There are two adjustment screws on
the carburetor. The low speed adjust-
ment screw is marked with the letter L,
and the high speed adjustment screw
is marked with the letter H. The throttle
lever is used to control engine speed.
The throttle lever can be placed in one
of four positions:
STOP, IDLE or "_,
FULL THROTTLE or _,
and one inter-
mittent position.
