Another sad story: I was flying my plane with a compact Fox 40 (C-case) that has the iron piston and stell sleeve. I flew it a couple of tankfuls and then suddenly it began to act up. I noticed that there was some dirt that got on the engine. I cleaned it thoroughly at home and took it back today for flying. The engine now quits suddenly at WOT even though it starts, idles, and transitons nicely. Seems like a compression loss when the engine heats up?
Any ideas to help with either engine is greatly appreciated.
Despondent it Detroit
A lapped engine usually won't exhibit the compression loss when hot like an ABC engine will. How does the engine feel when turning over cold and then turning over hot? Will it do the same thing if the HS needle is set a fair bit fatter? Did you read the glow plug? Try a new glow plug? Head bolts still tight?
