    1992 440 prowler 4000 rpm idle

    Hello I have been messing with the carbs for a while on my 92 440 prowler to try and get the idle back down but I cant seem to get anything to work. The air screw is about 2 turns out on both carbs and the idle doesnt change much if I turn them eith way. Ive cleaned out the carbs twice very good, so maybe you guys have some advise. Thanks.

    Welcome. Check for air leaks as in crank seals and carb boots, etc. It also sounds like the carbs need to be set up and put in sync. I am not familiar with the cat 440's per say but you need to set the slides and then work from there. I am thinking you have them hanging high in the bore and are trying to compensate with fuel and air screws. Start at stock settings on all screws and work from there. Unfortunately I can't help with specs. Sorry.
    Polaris...it IS the way out!
