Another Carburetor Help Thread…but I really need it.

[Lost81c10]

I need some help in trying to solve some issues that I’m having with my recently “rebuilt” carburetor.
First I will say that I had the carb rebuilt by this certain shop. The guy has not been able to get it right and I have to keep going back to. I am certain that it will be a while before it is completely fixed and running good but I paid and so I will keep going back.

But I need you alls help for now so that I can gain some knowledge so when I am dealing with the guy I can argue the points.

Now, looking at pic #7, is there supposed to be a hose hooked up to this  and if so what does it do or not do not having it there?

In pic #1 as you can see, the vacuum advanced is not plugged but it has a screw plugging the hose. Is this going to affect it for now? I tried hooking it back and when I did, the RPMs went up. What do I need to do with this to make it as right?

In pic #6, what the arrow points to (don’t know what it is called), but from what I know I think it is controlled by the choke and as the truck warms up it should slide down and bring the idle down well it is not sliding down and it takes a very long time unless I push it down but if I give it gas it goes back up and stays there. Why is this happening?

Last in pic #3 the hard ling is cracked, I need to replace it but where can I buy it. Is it just a regular part from any auto parts store? Thanks for any help and knowledge you can provide.

Truck is an 85 1/2t 305/350 and getting 10 miles per gl…anybody know of any good reliable shops in middle GA area to fix all this?
