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 s pecial tools r equired to perform all necessary modifications for
you.
Pilot screws are sealed with metal plugs and are serviceable o nly by
dealers.
