    I have an older Polaris Sportsman 500. I use it primarily as a plow for my long mountain driveway. It runs well in the colder weather but won't even start in the warmer weather. This summer, after trying to get it to start, I opened up the air filter box and found about a half inch of fuel...
  4. 2005 Sportsman 500 Throttle problem

    Polaris Sportsman
    Starts and idles fine but as soon as I give it throttle, it wants to stall(in any gear). Changing plug and oil tomorrow. A buddy said to drain float bowl in case of water buildup. Did this with no result. Problem started when I was plowing snow down hill and using ABS to some extent. At first...

  14. Carburetor Issues

    ATV Repair and Maintenance
    I've got a 1995 Polaris Magnum 425 4x4. When I rev it up and let off the gas and then rev it up before it gets back to idle it bogs down pretty bad. The air box is missing the boot on the intake also and was wondering if that might have anything to do with it running poorly. It does not idle...
