Post a better picture of the front driver side corner of your carb. It looks like something funky is up with your accelerator pump rod. (Looks like a wire over it)? The accelerator pump shoots fuel into the carb when you pump the gas pedal. That vacuum line with the hose clamp I assume is for distributor vacuum, I would just get that as one continuous piece of tube if that clamp is securing a union.

As earlier posts have said make sure fuel filter at front of carb is clear. Make sure you have correct wrenches when opening so it doesn't strip the fitting.

You can try putting a couple ounces of fuel directly into carb on your next cold start and see how it responds.

Put a list together of what you need to do and check off as you go. Step away from truck for awhile if you get frustrated or work on another part of the truck and come back later to issues that were getting you frustrated.

Looks like you just need to tidy some stuff up and you should be good.
