Why do i have to run my 96 polaris 400 2x4 atv in half choke when i ride


If you haven't taken that carb apart and cleaned it in awhile - more than likely your jets (what's used to pick the gas up out of the bottom of the carb (the bowl) are clogged up. You can pick up a can of carburetor cleaner with a wire basket inside from any major parts store specifically for carburetors to soak in. The size of a paint can & around $20. Soak the carb in that for awhile after disassembling, make sure none of your ports are clogged - air compressor gun or you can also use keyboard cleaner - air dusters. You want to verify that air can pass through all those ports properly and blowing air through them is how you do it. Carb does need to be completely disassembled to do this. The jets in the carb suck up fuel due to the vacuum the engine creates turning over. Once it starts spinning - it builds up a little suction and everything is fine. When the jets start to clog - one of the ways to force the carb to pull harder is to work the choke. The only thing that choke is doing is operating the butterfly. When the choke is on - the butterfly closes. Making all of that suction stay right there in the carb. Once the bike starts to warm up - you release the choke - and the butterfly will open - allowing more air into the system. You're running at half choke - butterfly half closed - to force those jets to pull harder. If they were clear? No need to run at half choke.

Polaris Scrambler won't idle when moving


If a tune up doesn't help, rebuild the carb. the ethanol in gas ruins the gaskets.
