TO ADJUST THE CARBURETOR
If you think your carburetor needs ad-
justing, see your nearest Sears Store.
Engine performance should not be af-
fected at altitudes up to 7,000 feet. For
operation at higher elevations, contact
your nearest Sears Store.

IMPORTANT: Never tamper with the
engine governor, which is factory set for
proper engine speed. Over-speeding
the engine above the factory high
speed setting can be dangerous. If you
think the engine-governed high speed
needs adjusting, contact your nearest
Sears Store, which has the proper
equipment and experience to make any
necessary adjustments.
