We just purchased this very used unit it was running But, it cut off today and appeard to be no fire i put a new coil on and made sure the coil had 12v going to it and a good ground still does not crank I Engine sounds like its not turning over fast enough but has a fully charged battery ( tested fine) I replaced the Dist cap and rotor still nothing I removed the spark plugs and turned the engine over and it appears there is alot of fuel being forced out, of the spark plug holes, ( spark plugs where also soaked in fuel)Is this normal and if not what could cause this? I am not familiar at all with carb engines
