I have a 2013 Polaris sportsman 500 ho and I cannot find the idle adjustment screw.
It will not stay running without keeping your thumb on the throttle.
I really would appreciate a picture pointing it out. I know where it is supposed to be based on my owner's manual - left side on the bottom of the carb. - but I can't locate it!!!
Ugh. Really could use a picture if someone is willing to post.

Thanks

 

Make sure you have 1/8" slack at the thumb throttle only. If it has too much slack the etc contacts will touch and it will die at idle. Idle adjuster is held in place by a wire spring close to the carb bowl. Springs were bad on breaking and the adjuster may be just flopping around down by the starter.http://www.cyclepartswarehouse.com/f...13&fveh=137567
