The Stovebolt Site Forums The Shop Area Engine Shop carb issue, runs rough for while, then stalls, then gas leaks out the backs

I don't think you mentioned how long your truck sat before you started it, but if it's more than a year or two, there's a good chance the fuel system needs a thorough cleaning. Usually the tank gets varnish built up in it as it sits. Then, when you start using it again, the varnish breaks loose and begins to clog the fuel filters and mess up the carb.

I'm pointing this out because, while rebuilding the carb might fix your problem, it may be a temporary fix until varnish screws it all up. One of the first things I did with my truck was remove the fuel tank and take it to a shop to have it flushed and sealed. I would suggest you put that on your todo list and make it one of the steps you do early on.
