MAINTENANCE
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.
