Purchased a 2002 220 Bayou that really needed some love. Choke plunger was stuck so I removed the carb, got that out and it cleaned up pretty well. I did not replace any carb part but cleaned all the passageways, jets etc. Checked float height. It runs great except the idle at times is erratic. You can be riding along, come to a stop, the engine idles down until it stalls. It always starts right up again. So I figured maybe the idle screw work out a bit....turn idle up then it afte a bit its idling to fast...turn back down to proper idle speed and it will be ok but eventually idle so slow it stalls. Took tank off, cables are routed properly. Checked fuel flow, that's OK. Installed new fuel line and small inline filter just in case. No change. Adjusted mixture screw both leaner and richer....no change. New plug (Old was burning perfectly tan). Adjusted valves...still no change. I'm now thinking maybe a vacuum leak at the intake manifold/carb boots (Oh, brand new air filter also). I also ordered a complete carb rebuild kit. I figure a good place to start just replacing everything. So does anyone have any other ideas? I'm running out of things to look at:frown: Like I said, at anything above idle it runs fantastic.
