Carburetor

NOTICE
Making non-recommended adjustments could result in vehicle or engine damage as well as denial of warranty claims. We recommend that all carburetor adjustments be performed by your POLARIS dealer.

Proper carburetor adjustment is critical, since a mixture too lean (too much air, too little fuel) will result in overheating of the combustion chamber, causing pre-ignition of the fuel. This results in piston burning, bearing failure or complete engine failure. A lean mixture can be the result of fuel line restrictions or foreign matter in the carburetor. A mixture too rich (too much fuel, too little air) is also unfavorable because it can foul plugs and cause generally poor engine performance.

All carburetors have been pre-set at the factory to the settings indicated by the shaded cells of the jetting chart on Carburetor Jetting. Higher altitude operation may require different adjustment and settings.

TIP
The number stamped in the end of the main jet indicates the jet size that was installed at the time of manufacture.
NOTICE
Using non-recommended jets and/or needles can result in shorter engine life, lower fuel economy, increased emissions and poor performance and drivability. Always use POLARIS-recommended jets and needles.

For questions about optional jetting for conditions in your area, your POLARIS dealer can assist.

Correct setup provides engine RPM within its given power band at full throttle settings and also provides maximum efficiency and operation at all other throttle openings. Your dealer can assist with carburetor adjustments, which may include the following:

  • Carburetor component changes for specific altitude and ambient temperatures

  • Choke adjustment

  • Idle RPM adjustments

  • Throttle safety switch inspections and service

  • Throttle block-to-throttle flipper clearance adjustment
