Steve,
I played around with that concept (along with cocking the throttle plate) after the Lancair Ada visit several years ago. I ended up having to pull out about 3 to 4 in. of MP to the mixture. Every engine will be different in this regard. The need for speed dictated I keep the throttle full open and just live with a rich cylinder. :-)

Chris and Scott,
The Advanced Pilot Seminar suggests experimenting with carb heat to improve atomization and mixture distribution. Those of us old enough to have messed with carbureted cars and heat risers understand the theory. The trade off is expanding the mixture by heating it. Might help, might hurt.

Yes, part of the problem is induction/mixture differences caused by the throttle plate position. I.E. WOT may be a quite different distribution than at partial throttle.
Uh, switch over to injection. Then you only have to deal with injector engine position locations resulting in differences in atomization of the fuel because of variable upper cowl air flow/pressure.
"....., not to mention the induction system limitations inherent carbureted engines."
Now you're on to something..
I fear my not-so-ideal mixture distribution would the limiting factor even with EI.
