Acceleration Test - Craftsman 917.271641 Owner's Manual

ACCELERATION TEST -
4. Move throttle control lever from slow to
fast position. If engine hesitates or
dies, turn idle mixture valve 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-govemed high speed needs
adjusting, contact a Sears or other
qualified service center, which has proper
equipment and experience to make any
necessary adjustments.
