Help me get the off-idle stumble out of my QF 750-AN Double Pumper

I put the "35" shooter in and that didn't seem to help so much. It did increase the time where it was rich after tip-in when shifting though.

I then switched to the 65 air bleeds and reset the mixture screws. That helped a lot. The stumble was almost gone, but not totally.

I tried raising the floats and it made it worse, so I dropped it back down to about where it was.

I do seem to be getting accelerator pump right away.

The distributor is a stock style one with a reset advance curve. I've got an FBO box on it (the A668 I think). I can try a few degrees in it as it won't be too far off on total. I'll get to that tomorrow.
