FIG, 38
TO ADJUST CARBURETOR (See Fig. 37)
The carburetor has been present at the factory and adjust-
ment should not be necessary. However, minor adjustment
may be required to compensate
for differences
in fuel,
temperature, altitude or load. If the carburetor does need
adjustment,
proceed as follows:
In generat, turning the adjusting needles in (clockwise)
decreases the supply of fuel to the engine giving a leaner
fuel/air mixture. Turning the adjusting needles out (coum
terclockwise)
increases the supply of fuel to the engine
giving a richer fuel/air mixture.
iMPORTANT:
DAMAGE TO THE NEEDLES AND THE
SEATS IN CARBURETOR
MAY RESULT IF SCREW IS
TURNED iN TOO TIGHT.
PRELIMINARY
SETTING -
•
Be sure you have a ctean air filter, and the throttle
control cable is adjusted properly (see"4TO ADJUST
THROTTLE

•
.Idle fuel needle setti[]g - With throttle control lever in
slow (,_!)
position, turn idle fuel adjusting needle in
(clockwise)
until engine speed decreases
and then
turn out (counterclockwise)
approximately
3/4 turn to
obtain the best low speed performance.
,
