Chris, would you be so upset if you had made the same purchase, for the same reasons(excitement coupled with distraction) from a seller at a show? Would you immediately demand he cancel the sale? After handshakes and all?
Yeah I would be pissed if I then walked around the corner and a group of people who knew about these engines all told me that I had just bought a fake (and a poor and dangerous fake at that) and that the seller had totally scammed me by lying outright about the engine.
