I don't think that is the problem since the idle mixture screw is after the floats. I think there could still be something interfering with the floats operation. It's hard to say without seeing.

This I guess was causing a pressure inbalance which forced fuel out of the jet thingy at the carb inlet and was flooding that cylinder - not as bad as yours. Not saying that's the problem but it's an indication of what can Happen
I'm having this problem when the bike is turned off it's leaking through a hole that's jus above the butterfly flap. You can see it when carbs on bike looking down into them. And it sounds like pressure is causing this!!! what is it? I jus had carbs off doing a deep clean!!! Please help I have a thred in general tech but no one has replaied to it yet!!! It would help me a GREAT DEAL!!!

same here, having the same issue.
The jets are all new, and new float valves as well.
Floats are original;, but are not leaking.
Starts fouling plug 1, then gradually does all of them.
My floats look higher than 13.7mm for sure, but I'm not young so could be my eyes lol.
Just blew air through all circuits of the carbs. Slides work properly as pressure is applied.
Nothing seams to be blocked.
Fuel filter is new, as is air filter.
Just waiting on some new O rings and seals to see if there was any issues there.
The bike is 22 years old, so its gonna have issues.
I bought mine as a running project, and now I've brought everything up too good level, the carbs prove to be the last hurdle......sigh
