Carburetor Adjustments
If the vehicle is to be operated at various altitudes and tempera-
tures, certain adjustments can be made to improve its operation
and driveability. Above 6000 feet (1800 m) the engine air/fuel mix-
ture becomes overly rich. An engine loses approximately 3% of its
power for each 1000 foot (304.8 m) increase in elevation. Al-
though this power cannot be regained, changes to the carburetor
and drive system can b e made to allow efficient operation. These
changes include:
1. Carburetorre-jetting to compensate foraltitude and/ortempera-
ture changes.
2. Transmission convertor modification to adjust for engine horse-
power loss during high altitude operation. Contact your dealer.
3. On 2 cycle models, air screw adjustments can be made to com-
pensate for temperature changes and/or changes in altitude.
4. On 4-cycle models, pilot screw adjustments can be made to
compensate for temperature changes and/or changes in alti-
tude.
NOTE: Contact your dealer for altitude adjustments. They have
the training and special tools required to perform all necessary
modifications for you.
