Since your idle screws are 1 1/4 out or so. Try cranking them all in a 1/2 a turn or more. See if that changes the vibration around.
Did any of the carbs need more or less ( Big difference ) air than the others.
What distributor do you have. MSD pickups get filthy. Whats your initial and...
Deffinately have to rejet the carbs with the layer of foam. I would guess two sizes or maybe more.
Someone could use the gromets for mesh or whatever.
The screen size I have is the 2.75 inch ones.
