By the way, the idle mixture screw is an air screw. Turn it out to lean the idle mixture. It lets air bleed into the idle circuit thereby leaning it out. Turning it in causes the circuit to bleed only fuel into the engine.

The other advice sure seems to be right on target.

It is possible, I guess, that the idle circuit is giving it way too much fuel.

Also, if the little brass tube which protrudes out of the lower body is broken off the engine can get too much fuel. I can't remember what part of the circuit it is, but I think it lets too much bypass.
