New here. Just got a 2002 warrior for next to nothing. In decent shape, low mileage clean engine. Wasn't running, but got it going with new battery, fuse and spark plug. It starts up a little rough and idles pretty week even with increasing idle speed, stalls sometimes unless given throttle. When driving the throttle cuts out intermittently mostly at low speed but at higher speeds too. Guy I bought it from is a friend and says it has a brand new carb in it so I dont think that's the issue. Any ideas? New to quad ownership, I'm handy but inexperienced.
