i have a 1994 Polaris Sportsman 4x4 400cc 2 stroke. having raced motocross, i understand that 2 strokes smoke anyway. this is a lot of smoke!
it is white smoke, and i am pre-mixing the gas with oil (36-1). when i bought the ATV, the oil pump was shot, and it wasnt worth the 420 dollars plus tearing down to frame. the oil pump was stuck in the full-open position, so it fouled plugs about once an hour (better than the alternative i guess) the pump is disconnected.
now it still fouls plugs, but more like once every 4th trip. runs great at throttle, but once back to idle, lasts about 4 seconds and dies. starts back up fine. idle screw is pretty high, and responsive. what is going on?
