MAINTENANCE AND LUBRICATION

Adjustments

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 atmospheric pressure and oxy-

gen loss.

2. Transmission convertor modification to adjust for engine horsepower

loss. Contact your dealer.

Contact your dealer for altitude adjustments. They have the training

and special tools required to perform all necessary modifications for

you.
Pilot screws are sealed with metal plugs and are serviceable only by

dealers.
