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 lawn mower to a
Sears or other qualified service center for
repair and adjustment.
CARBURETOR

fixed main jet for mixture control• If your
engine does not operate properly due to
suspected carburetor problems, take
your lawn mower to a Sears or other
qualified service center for repair and/or
adjustment.

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

proper equipment and experience to
make any necessary adjustments•
