I have a 2001 Sportsman 500. When I start it up it idles just fine. If I give it any throttle it bogs and dies. I can feather the throttle and keep it running but it won't really rev. So I took the airbox off and if I hold my hand the proper distance over the intake I can get it to rev and what not just fine. I don't see any adjusting screws really so I am expecting I will have to take the carb back off. Except I think there is a small screw on the bottom of the float that I can adjust. Anyone got any good ideas? Or even bad ideas are ok at this point.
