I had a guy trade me a 2005 polaris trail boss 330. When you first start for the day it runs great for about 10 minutes. After it gets all warmed up it starts popping and cracking out the exhaust and up through the carb. It also looses all of its power. if you let it sit and cool back down to room temp. it will run fine again. Can anyone help with a solution to this problem please.

Sounds like the engine get wrong mixture when its get warm. Try to change one grove on the jet needle. try first one step up.
Or have the engine works fine earlier and suddenly start doing this?

Oh i love my english :)
