I misunderstood the problem. It's easy to overtighten them when you attach them to the crank, but that doesn't appear to be the case with your pedals. I don't know, sounds like you got sold some bum pedals that were damaged somehow in their previous life. I have no other suggestions, but I hope you get them working properly soon!
