Well, from the description of the valve damage, one could make a case for
death by heat. But the report paints a pretty good picture of an ongoing fuel
supply problem and that will lead to a leaning condition that will also build
heat up pretty fast.

I think that if any other Franklin owners go the derated route, I would make a
QUALITY bore scope my best friend for a long time, and use my new friend very
frequently until I was satisfied that the valves weren't dying.
