ADJUSTMENTS
Carburetor
Your Polaris Quadricycle is calibrated at the factory for optimal perfor-
mance at altitudes ranging from zero to 1800 meters and temperatures of
4 degrees C. or higher. Above 1800 meters the engine air/fuel mixture
becomes overly rich and the engine loses approximately 3% of its power
for each 300 meter increase in elevation. Although this power cannot be
regained, adjustments to the carburetor and drive system can be made to
allow more efficient operation. Optional jets, available from your
Polaris dealer, are required for operation above 1800 meters. Jetting is
required only when operating below 4 degrees C. at 1800 meters and
lower.
NOTE: Operating the engine with improper jetting can cause poor perfor-
mance, overheating or engine damage. See your Polaris dealer for
more information about jetting.
