For me if the mixture screws have to be turned too far in say 1/2 turn from seated then I size down the ifr's and if they need to be like 2 turns out then bigger ifr's as a starting point. I size the idle bleeds according to the ifr's and go from there seeing/feeling the differences good and bad. I find the mixture screws play a HUGE role in how rich/lean the idle, transfer and cruise is on my Dart and there's a big difference between 1 3/4 turns out and 2 turns once it has heat in it. Same w/leaner mixtures, my car recovers faster when the happy peddle is mashed being in the 12-13 afr range while leaving a stop light and cruising instead of the 14-15's........... [/quote]

This is where I get confused. So; in my situation, I have a lean bog off idle but, my idle mixture screws are around a 1/2 to 3/4's of a turn from being seated. If you sized down the IFR's, then less fuel would be supplied to the transfer too and wouldn't that just make the condition worse?
