First, Congrats on what looks like a real cool truck

I read through the posts real quick, as someone else mentioned, ...fuel filter sock (on the sending unit pickup).
You mentioned sputtering, fuel starving, smell of gas, plugged up carb filter, etc. ...(sadly) been there done that. Absolutely 100%, if you haven't replaced the fuel sock, do it now.

Long story short, when I got my truck (68 C20 Utility, in signature) I went through it, rebuilt carb, pertronix, etc, etc. It ran fine...for a week or so. Gas all over the carb, so I sent it back to the rebuilder (In CA). Get it back a 2nd time, truck was running fine. Second trip to gas station, spitting and sputtering.
It turned out the fuel sock was totally disintigrated and (no surprise) were clogging the filter, clogging up the carb, etc. When I did pull the sending unit, I decided to clean the tank too. The tank (still in cab, along with it being an Arizona truck) was spotless inside, BUT ...fragments of the fuel sock all over sitting at the bottom. Once that was done, I have not had an issue since.

Good looking. Truck. Driving a classic that just putted around town, or garage run for years, is always a experience. Your just shaking loose what was ready to service. Nothing U mentioned is out or ordinary, your just on a steep analog learning curve. Enjoy..
