Solved it on my own. It was the carbuetor. Easy carb to work on with out having to remove it. First, removed the bracket in front of it. Then removed the 3 screws that holds the "frame" on the front plate of the carb. Used a knife edge to gently pop off the bowl plate. I found sludge in the float bowl and jets. Used carb cleaner in a can to clean the gunk out, and stuck the nozzle in the jets and orfices to clean them out. Put it back together and Voil'a! The truck is running like a champ.
