Just a thought,

How much of a turn is your idle speed screw in? ( On the linkage. ) Not idle jets, but idle speed.

You may have the butterflys open too much bleeding fuel from the main circuit.

This will really screw you up trying to get your idle jet size right and adjusted correctly.

If you ok there, back off your nuts and go a size down on idle jets.

I didn't read every post, but you timing needs to spot on in all of this.
