CARBURETOR ADJUSTMENT

Never make unnecessary adjustments to the

carburetor. The carburetor was set at the

factory to operate efficiently under most ap

plications. However, if adjustments are re
quired, we recommend you contact your
nearest Sears Service Center.

WARNING: The engine gover

nor is set at the factory. Do not
change the governor setting.

Over speeding the engine above the fac

tory setting can be dangerous. If you
think the engine governor needs an ad

justment, contact your nearest Sears

Service Center.
