Hi All, my PK1 Carb is running really rich..Even idling for very short period of time, it fouls the plug. Ive got fuel mixture screw turned almost all the way in. Even with mixture screw turned all the way in, the engine doesnt stall. Am i missing something here?? Its a brand new carb. Was thinking about a leaner pilot jet, but the one thats in it, as far as i can tell is an .020. Dont think they even sell a leaner one than that. Could this possibly be a float level problem or something else. While engine is running, when i shut the fuel valve off. As the bowl empties, the engine rpms come up and it smooths out. Obviously less fuel, leaner mixture, i get that. Im perplexed, dont know what to do next. This isnt normal for this carb, is it?? High speed circuit seems fine. But i cant tell if that mixture is right either because the plug is always full of soot from when it idles...Plz help
