1961 Chevrolet Impala

I have a 1960 Impala with a 348 engine (tri-power) running ONLY on a single 2GC carb. It runs great, but when it gets warmed up after an hour or so, and I turn it off for a few minutes, the idle is very rough. So rough that I can hardly back it into my garage. Any thoughts?

Is the linkage working? Is it progressive or do the other 2 come in about 1/2 throttle?

Those rodchesters are easy carbs to work but the center one is the only one with idle controls.

If you put your hand over top the center, does it idle better?
