ENGINE
ENGINE SPEED
Your engine speed has been factory set.
Do not attempt to increase engine speed
or it may result in personal injury. If you
believe that the engine is running too fast
or too slow, take your unit to a Sears or
other qualified service center for repair
and/or adjustment.
CARBURETOR
Your carburetor has a nonadjustable fixed
main jet for mixture control. If your engine
does not operate properly due to sus-
pected carburetor problems, take your unit
to a Sears or other qualified service center
for repair and/or adjustment.
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, take your unit to a Sears or
other qualified service center, which has
proper equipment and experience to make
any necessary adjustments.
