I've got a question.
Why should he have to pay shipping when the engine you shipped was junk? He already payed to ship it once.
Look at the crank.... it has rust on it. Rust takes time to develop, so I would say that your story of "him pouring something over it" is bs.
You are a rip off and the guy was smart enough to catch you. There is not a judge in any court who will side with " I didn't know it was junk that's how I bought it"... You are still responsible for the sale. It is your responsibility to go after the guy who sold you the junk engine. If that is truly what happened :roll:
