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.
