Doug,

At power settings above 65% you need to be concerned about running too
lean, thus too hot.

Uhm, no, not at all. He'd have to be concerned to run not lean enough,
actually, since the temps decrease again when running leaner and leaner.
The point is: You have to worry to run at the right point in relation to
peak.

With monitoring all 6 cylinders it should be
possible to run 50 to 100 rich of peak at these high power settings.

50 rich is about the worst point to run at.

Most of us pilots lean to a specific EGT.

Well, I sure don't. I don't know ANY other pilot (apart from you) who
does. Those numbers are completely irrelevant. The relation to peak is
key.

I have an engine that is well over TBO and still
going strong using this technique.

I can't see any curvature of the earth from the ground, so it must be
flat. Or, in other words: What proof do you have of a correlation?


Lean on the ground for taxi as much as possible. Lean for takeoff at
airports above 3000'.

Density altutide, not actual altitude, I'd like to add. VERY important!
