Clinton Chain Saw Engine!

This little engine was a yard sale find! I got it for the perfect price! And when I say little, I really mean little! I initially thought it was an old McCullough engine, but it turned out to be a much more rare, and maybe older little engine than I thought. Finding information on this engine has been a challenge to say the least. Finding parts is proving to be even more difficult. If I ever can find (or fabricate) the missing exhaust this little engine is going to make for a really cool little go cart engine. Oh… By the way… Does anyone have an exhaust for what I think was probably a Clinton D32?
