All Balls Racing – Carburetor Rebuild Kits - Polaris, including kits for the 95-96 Magnum 425 2x4, the 99-00 and 2002 Sportsman 500 4x4 and 4x4 DUSE, the 03-04 Sportsman 600 4x4, and the 08-15 Outlaw 50. Each kit is built around the parts that actually wear on a Polaris carb: needle and seat, float bowl and pilot screw gaskets, o-rings, diaphragms and jet-block seals matched to the exact carburetor that machine left the factory with. Those soft parts harden and shrink with ethanol and time, which is where hard starting, hanging idle, bogging off the bottom and fuel weeping from the bowl come from. Replacing the whole set restores the metering circuits instead of chasing one symptom, so the machine idles where you set it, pulls clean through the midrange, and stops loading up on long low-speed trail runs. The pilot circuit parts matter most on machines that spend their life at trail speed. Polaris used several carb variants inside the same model year and engine family, so give us your year, model and drive configuration and we will confirm the correct Polaris carburetor rebuild kit for your carb before you order it.
