I'm not trying to flame anyone here, but when you buy something with no warranty and both parties agree to it, why would you even consider asking for all/some of your money back? That's what would happen if there was a warranty. If you didn't get what you were expecting, you essentially agreed that that would be O. K. with you. Even with the engine in non running condition, the parts alone are worth what you paid for them even if some work has to be done. Hope you get it worked out.
