Well, I picked the truck up last night and it runs like a top. The mechanic would not share his method of fixing it. Said that he set the carb and timing by ear. He told me that he grew up on this motors. He would not tell me what he did because I would go buy Craftsman tools and do it myself. Whatever....
I'm just glad it runs good. I drove it around last night just to make sure it would be up to a trip to the ATHS truck show tomorrow.
