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.

Chris,

 

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.

Now you're on to something..

I fear my not-so-ideal mixture distribution would the limiting factor even with EI.
