Update. Thursday night, we pulled the carb off. Found a busted vacuum line at the back corner of the carb, by the valve covers. Replaced the line, and gasket. Put it all back together. Guess what?!?!?!?!

Wrong. Still acting the same. Squirt the brake cleaner dead center of the throttle bracket, engine will purr smoothly.

Hopefully going to pull it back in the shop today, and take the carb back off, and take a look at the back of it and try to figure out what is going on. I know everyone says to replace the carb with a Webber, but I don't have the money. I dropped my entire savings account into buying this truck and getting it to where it is today. We have nothing left, and I still have to come up with money for my trip next month to pick up my son for his graduation, which I don't see happening. But I gotta, cause he is coming to live with me.

But going through the Haynes manual. It talks about some type of "wax" valve on the back of the carb, under the throttle cable bracket? Anyone have any clue to what this is? That is about the area that we believe it is leaking from.

Someone else told me to just tap out the cover over the mixture screw. Back it out 3 1/2 turns, and forget about the vacuum leak, as that would fix it as well.
