Yes, it idles especially rough the lower it goes. It also seems to “hunt” between 500 and 600.
I discovered a couple of vacuum leaks yesterday and thought I had fixed them by removing the base gaskets from the carburetors, cleaning them, and forming a very small (cross section-like a pencil lid) of form-a -gasket on all 8 surface and reassembled them. It’s hard to believe I still have a vacuum leak but certainly possible. There was also an old smog kit tap into the intake manifold I resealed.

Not sure what you mean by 'marginal'. Does the car run rough and act like it's gonna stall ? If so, I would attach a vacuum gauge to the intake and see what's going on. Problem is either a vacuum leak, or something is out of whack in your carbs. It's not Ethanol gas.
