Will revisit idle mixture, but I do have screws turned out further than I ever have on my cars. I have suspected vacuum leak, but found none listening with an instrument and introducing propane around all surfaces on top of engine and around carb. None found. My carb was rebuilt by Charlie. He has been helping me trying to figure this out.
