Man that's rough, but I can understand your position.
I assume from your post, the owner did nothing to preserve the engine while it was idle? There are ways to do that, but it sounds like it was left in running condition.
He may have a ahard time selling it.
Good for you, though. You had the presence of mind to walk away from something you considered a bad deal. That's hard to do, but it shows good judgment and the ability to stick with your decisions.
Good luck in your seach.
