TO ADJUST THE CARBURETOR
The carburetor is not adjustable. Engine performance
should not be affected at altitudes up to 7,000 feet. For
operation at higher elevations, contact your nearest autho-
rized service center.
IMPORTANT: Never tamper with the engine governor,
which is factory set for proper engine speed. Over−speed-
ing the engine above the factory high speed setting can be
dangerous. If the engine−governed high speed needs an
adjustment, contact an authorized service center. They
have the proper equipment and experience to make any
necessary adjustments.
