i have a 71 johnson 50 hp that won't start.<br />it has spark and is getting gas but when you turn it over it just pops and spits.<br />the new parts i put on it are: power pac, stator plate, rectifier,head gasket, and ignition switch.<br />the carbs are clean and the coils work.<br />the motor hasn't run in 4 years but with all of the new parts what the heck is left to go wrong?<br />also, compression is good.
