RE: Fitzpatrick engines?
I ran for a while in a LT-40. It was a nice running engine but nothing to get excited about. The muffler was great to look at but not much of a muffler.... loud!
All in all probably one of the best made, best looking engines ever but as others said, nothing a modern .60 wouldn't keep up with. In fact, they weren't anything anything a 70's vintage S.T., Profi, or Webra Speed wouldn't keep up with.
They were expensive even back then and more expensive now. If you just want a good .60, buy a Thunder Tiger .61 pro. If you want a pretty and somewhat rare engine, buy a Fitz.
