Carburetor Adjustments
If the vehicle is to be operated at various altitudes and temperatures, certain adjust-
ments can be made to improve its operation and driveability. Above 6000 feet (1800
m) the engine air/fuel mixture becomes overly rich. An engine loses approximately
3% of its powerforeach 1000 foot (304.8 m)increase in elevation. Although this pow-
er cannot be regained, changes to the carburetor and drive system can b e made to
allow efficient operation. These changes include:
1. Carburetor re-jetting to compensate for altitude and/or temperature changes.
2. Transmission convertor modification to adjust for engine horsepower loss during
high altitude operation. Contact your dealer.
3. On 2 cycle models, air screw adjustments can be made to compensate for temper-
ature changes and/or changes in altitude.
NOTE: Contact yourdealer for altitude adjustments. They have the training and spe-
cial tools required to perform all necessary modifications for you.
