Car runs fine outside of it wants to bog down on acceleration from a stop.

I've read a bunch of older posts on how to tune the 1100. I feel like I've got a decent understanding but still have a few questions before I dive in.

If I'm tuning with a vacuum gauge, does the distributor need to be connected or disconnected from vacuum. Loadomatic

Where are my fast and slow idle screws?

The one at the base is the air/fuel mixture?

The one off the linkage is my throttle stop?

The only other adjustment I have is this nut off the choke linkage but choke seems to work as it should.

The bottom screw (last pic) is the idle mixture.
Bogging at acceleration is usually the accelerator pump. If the engine idles well, changing any of those screws is not advised. None of those screws will assist with an off idle bog. At most reset the idle mixture. Engine warm, choke open, idling. Begin turning the screw in (right) slowly until the engine rpm drops. then back it back out 1/8 turn at the time and listen to rpm. Using a handheld tach can be helpful, but your ear is just as good if you go slowly and listen. Keep opening the screw 1/8 turn and pause until the idle sounds best and is at best rpm.
Don't expect this to eliminate the bog, unless the mixture was very lean before the adjustment. :)
