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 engine is running too fast or too slow,
take you r mower to a Sears or other qualified
service center for repair and adjustment.
CARBURETOR
Your carburetor has a non-adjustable 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.
IMPORTANT: Never tamper with the engine
governor, which is factory set for proper en-
gine speed. Overspeeding the engine above
the factory high speed setting can be danger-
ous. 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.
