If I had this problem, I would install a new spark plug, start the engine, adjust idle speed with the idle speed screw, NOT the idle mixture screw, let it run until it dies. Then remove the plug and see what color it is. If it is at all sooty it's too rich. If it looks like it just came out of the box - it's too lean. It could be an ignition problem, if it is not a fuel problem. Coils have been known to cause this problem. Have you checked to make sure the carburetor is snug to the cylinder head? If it is sucking air at the flange, that could cause this problem.
