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

I think going to the .033 idle feed restrictors will be the last thing you will need to do, But lets say you put the .033's in and it still has slight stuble, then try the .061 idle air bleeds. But I think your problem will be gone with the .033 idle feed restrictors and the .065 idle air bleeds.
I had the same exact problem with my carburetor, my carburetor out of the box had .070 idle air bleeds and .031 idle feed restrictors and .031 squirter with a pink pump cam. I ended up running .033 idle feed restrictors and .065 idle air bleeds a .035 squirter with a hi-flow screw and the white pump cam on position number 1 and each step took the stumble away a little at a time, the last thing I did was change the idle feed restrictors and that took it completely away.
