Hey guys, I'm having a problem with my 04 polaris predator 500. It will start up and idle great, but then it it gets to operating temp./ warmed up and idles up extremely high so I run over to it and shut it off. When I am riding it and pull in the clutch it does the same, idles up extremely high. The only way I can control this is having a load on the engine such as applying the brake when it is in gear to keep the rpms were they should be. And no, it is not the idle screw. I swapped carbs from a parts four wheeler and it does the same thing. I also saw the thread when a dude had the same problem and it was his throttle cable. I have yet to get the new one in to see if that is the problem. Leaning towards a vacuum leak but I've coated that thing with carb cleaner and couldn't find anything. Any help would be appreciated!
