2008 Polaris Outlaw 525 high idle and stall

[Blizzy525]

I have an 08 Outlaw 525 that starts up no issues but after a few minutes will begin to idle high and then just shuts off. Checked my air boots to the carb and everything looks fine. Oddly I jumped in it and drove it no issues but stopped to park it and it again high idled. Here’s what it sounded like but didn’t shut off after riding it this time

It sounds like it's going too lean..  Have you checked the fuel flow to the carb is adequate ? The best way is to turn the fuel tap off, then undo the carb drain screw and watch it flow out, then turn the fuel on and make sure it keeps flowing good. Then, with the engine warm, try adjusting the idle mixture. It should respond to a half turn either way, if it doesn't respond to a half turn in each direction(too lean and too rich), then there's a problem in the carb..

Another thing that might cause it would be tight valve clearances..  Unlikely if it has shim adjusters though.

Oh.. Tank breather too.. check that too, though that normally takes a while to manifest..

It does sound like it's running out of gas, but no spitting or sputtering it just dies. It sounds like it's idling at about 3000 rpm. I generally run mine carbs dry if I am not going to use it for a while and they don't sound like that, they slow down and then speed up before they die.

Good point Gw..  That is mostly the more common scenerio.. 

Thinking thinking...

I can't her that video.. bad internet..

So it's just running high steady revs is it, then suddenly cuts out ?

Carby breather hose blocked ?

Does it restart easy and straight away ?
