Idle Screw - Running Issue on a '33 BB

[30AAFord]

New fuel pump is from Mac's - went with later glass bowl style (that's what was on the engine when I got it and liked the ability to check sediment collection). Have not tested pressure.

I can see no open ports on the 59A base, but will check again when I see the truck next.

Don't have a vacuum gauge, but looks like I need to get one. How am I hooking the vacuum gauge to fine tune carb? Am I using the port on intake that connects to vacuum advance line for distributor?
