Hi Phil:
Thanks for the reply. I was beginning to think that nobody had used this engine.
Back in the early days of HAMS Sport Race, Gill tried one of these engines with a BB front end. The problem that he had, starting was a severe problem. At the time, I thought that he had an engine that had a very poor ring/ cylinder fit. The engine that I picked up is new with a great ring fit! Now to break it in without losing that fit! This engine is quite large and heavy. A stunt engine, I do not know, but it will be fun to run!
Stay well,
Frank
