RE: McCoy engines
Hank:
I've never had much chance to say anything about these engines except for the "Red Head Stunt" line. The others were all excellent, the one I posted the picture above won several speed contests for me, and I had excellent service from the Red Head 60 engines as well.
But I never saw one of the "Red Head Stunt" engines last more than a couple hours. All I am relating is my personal experience. Others have said theirs lasted longer. Maybe I was always getting the Monday and Friday engines. I just don't know.
If you make a new cylinder and bush the case I'm sure it will really last longer than just the weekend. It was never the piston that wore so badly, but it did lose its fit. With a new cylinder you can reestablish the fit, and given care and 100% castor oil it will probably run well.
