FINAL SETTING -(See "TO ADJUST
THROTTLE CONTROL CABLE" in this
section of the manual.)
1. Start engine and allow to warm for five
minutes. Make final adjustments with
engine running and shift/motion control
lever in neutral (N) position.
2. Move throttle control lever to slow posi-
tion. With finger, rotate and hold throttle
lever against idle speed screw. Turn
idle speed screw to attain 1750 RPM.
3. While still holding throttle lever against
idle speed screw, turn idle mixture
valve full travel clockwise then coun-
terclockwise until engine runs rough.
Turn valve to a point midway between
those two positions. Release throttle
lever.
ACCELERATION TEST -
4. Move throttle control lever from slow
to fast position. If engine hesitates or
dies, turn idle mixture valve out (coun-
terclockwise) 1/8 turn. Repeat test and
continue to adjust, if necessary, until
engine accelerates smoothly.
High speed stop is factory adjusted. Do
not adjust or damage may result.
IMPORTANT: Never tamper with the
engine governor, which is factory set
for proper engine speed. Overspeed-
ing 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 service center, which has proper
equipment and experience to make any
necessary adjustments.
