RE: Irvine Engines
I bought a new Mark ? Irvine .40 and ran it for YEARS on a Goldberg Tiger. I finally sold it on the plane after just getting tired of the plane. This was one of the best 2-strokers I ever had. Ran absolutely perfectly - idled great, never a dead stick, powerful, smooth. Always started right up. Great carb. I think you could run this engine 50 years without wearing it out. I could see no signs of ANY wear on the great chrome liner, and of course it did not peel or wear like an OS liner. This was after many, many hours of operation over about 16 years.
Should have kept the engine and sold the plane.
