Carburetor Adjustments
If the vehicle is to be operated at various altitudes and temperatures,
certain adjustments 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 power
for each 1000 foot (304.8 m) increase in elevation. Although this
power cannot be regained, changes to the carburetor and drive system
can be 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 4-cycle models, pilot screw adjustments can be made to
compensate for temperature changes and/or changes in altitude.
NOTE: Contact your dealer for altitude adjustments. They have the
training and special tools required to perform all necessary
modifications for you.
