FWIW: There is little to NO advantage to running a gasser overly rich IMO and in fact its detrimental to the engines long term life expectancy.

I don't plan to run it "slobbering rich", but I think running the engine "a LITTLE on the rich side" will not decrease it's long term life expectancy enough to worry about. The engine will probably outlast me anyway.
The big advantage to me is to not loose a prop and spinner from a backfire or have the engine die in the air forcing a dead stick landing.
I suspect once it is fully broken in it will be less sensitive to the carb adjustments and I will be able to trust it running leaner.
