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.
