Thinking your carburetor needle/seat isn't holding...and your running flooded ..! Rich...black smoke...if tank is gravity feed, sittiing overnight, you're also overflowing into the intake, down pass the rings into crankcase, and running with diluted oil...which offers white smoke and oil fouled plugs...Don't run till fixed...pinch the fuel line with vice grips when stored...Otherwise, I suspect you do have a blown head gasket....as others have mentioned..but color of smoke is misleading for now...
