Look really closely at the joint where the crank case attaches to the block. If need be, clean it with Simple Green, let it dry thoroughly and run the motor. Look for fuel and air spitting out from the joint, with a flash light and small mirror, as the engine is sneezing.  If fuel leaks out, air can leak in, causing the sneeze. This is only after checking your reeds, of course.

Long live American manufacturing!
