Is anyone in this group interested in or experimenting with Lean of Peak
operation? I'm especially interested in the experience of anyone doing it
with a fixed pitch carb engine with single EGT and CHT probes.

I am Roger, but I've got a ways to go yet before I'll be able to try
it. I'll be using a Ford V6, and I'm just now getting ready to
fabricate the headers. I'll be drilling each exhaust tube for an EGT
probe and hope to scrounge the money to get one of the multi cylinder
types.

Then I have to run the engine for an extended period while documenting
the tests so that the DAR who looks things over will at least be able
to see that the engine was run at flight power settings for extended
periods.

During the runs, I'll be seeing if I can bring the mixture to lean of
peak without misfiring.

In theory, the engine should lean way down without getting rough
because I've modified the intake manifold and also am fabricating the
exhaust system with equal length runners, which collect into two
pipes.

But theories have a way of not working out as planned. I'll report
once the engine is running.
