High Altitude Use

Carburetor Modification

NOTICE
When carburetor has been modified for high altitude operation, the air-fuel mixture will be too lean for low altitude use and may cause engine damage.
At high altitude, the standard carburetor air-fuel mixture will be excessively rich. Performance will decrease and fuel consumption will increase. A very rich mixture will also foul the spark plug and cause hard starting. Operation at an altitude different than that which this engine was certified, for extended periods of time, may increase emissions.
High altitude operation can be improved by specific modifications to the carburetor. If always operating the generator at altitudes above 3000 feet (915 meters), have an authorized Polaris servicing dealer perform the carburetor modification. The engine will meet each emission standard throughout its life when operated at high altitude with the carburetor modifications for high altitude operation.
With the carburetor modification, engine horsepower will decrease by about 3.5% for every 1000 feet (300 meters) increase in altitude. The effect of altitude on horsepower will be greater if no carburetor modification is made.
caution
Operation of the generator at an altitude lower than the carburetor is jetted for may result in reduced performance, overheating, and serious engine damage caused by an excessively lean air/fuel mixture. Be sure to have any modification reversed at lower altitudes.

Altitude Kits

For added convenience, POLARIS offers high altitude kits which optimize performance and fuel consumption at various altitude ranges. For installation instruction, see High Altitude Jets.
