ACCELERATION TEST-
4. Move throttle control lever from slow to
fast position. If engine hesitates or dies,
turn idle mixture valve out (counterclock-
wise) 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 service center, which has
proper equipment and experience to make
any necessary' adjustments.
