I don't know if this is what it is called but I'll try to describe it.
My brother-in-law has a B that has a lift system the appears to run off the exhaust. He is not sure if all the parts are there. Does anyone have pix of anything like this or know where I can find them. That is If I am talking about the right thing.
I figure if I help him with this I might have a better chance of weaseling him out of...I mean dealing with him on getting that buzz saw/stationary engine he has sitting around collecting rust.
