Ross, reading your post reminded me of another aspect of ground leaning. I
also start the engine with the mixture in the ground lean position, which is
maybe at most 1/2 inch forward of idle cut-off. Starting has always been
easy with just a single pump of the throttle both hot and cold.

yeah but that depends entirely on how the throttle pump on your carby
is set up. (there are 3 settings on the schebler)
mine would behave like that but would die on throttle increases at
altitude. it is now changed to give correct prime with 3 pumps and
doesnt die when throttle is increased at altitude.
there is a little plate that drives the actual pump plunger that has 3
holes in it.
