How to Adjust a Polaris Carburetorby Charles Poole
The carburetor on your Polaris ATV is used to bring fuel into the engine. If you are getting stalls or your engine will not turn over, you need to adjust the carburetor. Jet pins and an air adjustment valve are attached to the carburetor. This valve will allow you to reduce or increase the air flow to your engine. You must adjust this valve according to your altitude.
Turn off the engine and remove the ignition key. Wait for the ATV to cool. If you do not, you might burn your hands while adjusting the carburetor.
Locate the gold pins on the side of the engine. The fuel jets and the air valve are on the bottom of the engine. Open the owner's manual and locate the adjustment chart.
Tighten the jet pins with a screwdriver until they will not go any tighter. This calibrates them to zero. Refer to the adjustment chart to see how many turns the pins need for the proper calibration. Use the screwdriver to adjust the screw on the air valve the same as the jet pins.
