I think we are confused, he is not sure what he has, thats his question. There is a serial number on the motor, kind of below the carbs toward the front of the engine. Also the majority of the 1250 have four emission ports by the spark plugs. they are blocked off but they are obvious. The seal would be hanging on a very short wire on the very front of the engine, it act as a lock. The engine number would be helpful.
