PRELIMINARY SETTING -
• Air cleaner assembly must be as-
sembled to the carburetor when
making carburetor adjustments.
• Be sure the throttle control cable is
adjusted properly (see above).
FINAL SETTING -
• Start engine and allow to warm for five
minutes. Make final adjustments with
engine running and shift/motion control
lever in neutral (N) position.
• Move throttle control lever to slow
position. With finger, rotate and hold
throttle lever against idle speed screw.
Turn idle speed screw to attain 1750
RPM.
• While still holding throttle lever against
idle speed screw, turn idle mixture
valve full travel clockwise then counter-
clockwise until engine runs rough.
Turn valve to a point midway between
those two positions. Release throttle
lever.
ACCELERATION TEST -
,, Move throttle control lever from slow to
fast position. If engine hesitates or
dies, turn idle mixture valve out
(counterclockwise) 1/8 turn. Repeat
test and continue to adjust, if neces-
sary, until engine accelerates smoothly.
High speed stop is factory adjusted. Do
not adjust - damage may result.
IMPORTANT: Never tamper with the
engine governor, which is factory set for
proper engine speed. Overspeeding the
engine above the factory high speed
setting can be dangerous. If you think the
engine-governed high speed needs
adjusting, contact your nearest autho-
rized service center/department, which
has proper equipment and experience to
make any necessary adjustments.
