AcampoDave, I will try to check timing tomorrow. Going to buy a timing gun and vacuum gauge. I have been reading and watching videos, hopefully I can figure out the timing.
My front door neighbor thinks the timing is good because it won’t backfire during idle.
Caprainfab, thanks for the clarification on that port.
The trans modulator line goes to a “T” fitting with another line that I believe is the secondary choke diaphragm? Then the 1 line goes to the back of the carb.
I will separate the line tomorrow and run the trans modulator alone to the intake manifold.
Yes, I do have a vacuum line from distributor to the carb, the line goes to a vacuum port on the front of the carb.
Can’t find a diagram online to show what the rest of the ports are.
I think the broken piece of the carb is where someone popped the factory cap off to adjust the idler screw, or not.
Does it matter if this blue valve isn’t connected to anything?

I agree that timing sounds like the issue. What is that blue port, I can't tell from the pic but I would plug it. Vacuum leaks can make a good motor run like crap. If you can get the truck to idle, I would spray starter fluid on any possible vacuum leaks and see if your rpm increases.
