Stock setting for the idle screw is 1.5 turns out. therefore that large of a idle jet would not be needed.
Plus, the linkage has no slop, they are adjustable. 1 side should close almost all the way while the other side is open a bit. #2 IS stationary but 1,3, and 4 are adjustable. You take a 1/8 inch drill bit and use the shank and set all 4 to the same amount, called a bench sync. This is the way they should be.
The only linkage that could have slop is the choke link as 1&2 are separate from 3&4.

I know you have done your testing but I have too. I have learned these carbs inside and out for over 15 years. I can, in virtually all exhaust changes, say that rejetting is not required except in all but the most extreme cases such as drag pipes.
