Default Re: what are these engines made of?

I don't know, my buddy's engine ran fine that way, he had to tighten the screws down once or twice, but after that he just loctited them and that was that, ran it for over a year like that. At most I'd say buy the new case but wait until you actually have a problem to swap it out. Case swapping is no easy job for a beginner.
