Gaskets

[Dean Pappas]

Hi John,
Let me tell you a story from '83 or so...
A local flyer, who had great luck with his several Rossi 60s bough a new one for that season. After a tank on the ground for break-in, he "leaned" on the engine, and it ran great for about 1 minute. Then, it started to lean out, and the idle got fast and inconsistent. All the normal fixes were tried: the bearings changed, the carb boss sealed and re-sealed, until Sal Battaglia (one heck of a flyer and a great engine doctor) suggested transplanting all the same parts into a new crankcase. It worked. It turns out that the crankcase casting was porous, and after warmup it was a big air leak.

I bought an airplane & engine from the Russian team at the Pensacola Worlds
a while back. I eventually sold the airplane without the engine. The engine
(YS140FZ) shows signs of a desparate attempt to fix an air leak. It has
spots of JB weld(?) here & there. When it is idling, the sound is unstable.
The speed variation is not measurable with my tach.

I choose to ignore te problem because it runs as well or perhaps better than
any of my other YSFZ140's!

A piston/liner might fix it, but it will take more than the current symptom
to get me to open it!
