Is this a G or an E model
pilot jets are not a 120 either, so look at those again.......... you may be talking the pilot air jet, not the pilot fuel jet
idle mixture screws are for fuel not air....
Did you synchronize the carburetors?
Are they actually completely clean throughout all the circuits, not just new jets installed?
You don't specify loads or temp etc as to when these conditions are most prevalent and if they get better or worse as the temperatures rise.
How many miles and have the valves ever been adjusted, and when was that?
Do you know whose needles (dyno jet, factory pro, Muzzy etc....)
pilot air jet size
pilot fuel jet size
needle
needle jet
main air jet
main fuel jet
can you say what all these are?
