Thanks everyone. That would make a lot of sense. My dad bought this car in the mid-60’s and the prior owner had a Ford dealership and garage. There were other modifications done to it as well.
Jerry in Shasta, is the port in the upper casting? Is this the same thing Sparky mentioned as the idle passage? I haven’t identified it with my drawings. There is an opening in the throat just above the throttle plate but it’s closed with a small brass screw.

My cold start procedure is very similar to yours, I only choke 1 or 2 revolutions and it starts fine. My problem began in attempting to get to a slow idle. It doesn’t respond to the idle air mixture screw. I don’t know if the slight carb leak at startup is related to that or not. Does seem to be...
I’ll check the idle passage, haven’t tried that. I’ll bet that the leak is coming from weep hole, I can’t find anything else leaking. It isn’t much but it shouldn’t be dripping at all and it’s only at start-up.
I pulled the drain plug and the main jet is tight. Throttle shaft does have some slop in it, can pull it back and forth (or in and out) probably 1/8”. Don’t have a vacuum wiper line, plug in manifold is tight. Engine doesn’t die when idle mixture screw is closed. I did take it out though and it...

Thanks
