control lever in slow position, engine

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.

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, contacta Sears or other qualified
servicecanter, which has proper equip-
ment and experience to make any
necessary adjustments.
