• While still holding throttle lever against

idle speed screw, turn idle mixture
screw in (clockwise) until engine
begins to die and then turn out

(counterclockwise) until engine runs

rough. Turn screw to a point midway
between those two positions.

• Continue to hold throttle lever against

idle speed screw and adjust idle

speed screw to obtain 1200 RPM, if
the governed idle spring is red, or 900

RPM, if the governed idle spring is

white. Release throttle lever.

ACCELERATION TEST -

• Move throttle control lever from slow to

fast position. If engine hesitates or

dies, turn idle mixture screw 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.
