NOTE: The high idle is set at the factory

and cannot be adjusted.
2. Idle speed setting - With throttle

control lever in slow position, engine

should idle at 1200 RPM. If engine
idles too slow or fast, turn idle speed
adjusting screw in or out until correct
idle is attained.

3. idle fuel needle setting - 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.

4. Recheck idle speed. Readjust if

necessary.

ACCELERATION TEST -

5. Move throttle control lever from slow to

fast position. If engine hesitates or

dies, turn idle fuel adjusting needle
out (counterclockwise) 1/8 turn.
Repeat test and continue to adjust, if

necessary, 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 a Sears or other qualified
sendee center, which has proper equip­
ment and experience to make any

necessary adjustments.
