Craftsman B&S 18.5 HP OHV
Have problem with gas getting into the oil + oil into the carb from the breather tube. Replaced carb, changed oil & filter. Engine started right up, ran great for a couple of minutes, then engine started smoking as before. Heavy oil vapors again in the breather tube going into the carb. Replaced oil was at the correct level and gas shut off already was installed. Anybody have any suggestions other than a cracked piston or head gasket?
