Don't get me wrong, its not fixed completely (choke is still an issue). Not sure how well the truck will start when it's cold again. After warming up and fixing the timing, the truck started very well. I can manually shut the carburetor and start it later when it's cold...I guess we'll see. I'll report back later.

-If you rebuild a carb, will that fix the choke?
-What does it cost to rebuild a carb? Either myself or a pro
-I currently have a 2BB carb so wonder if the cost is high enough to upgrade to a 4BB carb and intake? I know I want to but I'm too cheap ;-)
-Even when warm, the truck had a slight hesitation when I hit the throttle. I gapped the spark plugs at .40, maybe .45 is better?

thanks for all your advice.
Hey its cool. Im not the most inclined here by far though. I took my old 74 van over to my father inlaws and it ran pretty bad at the time. He adjusted my timing by feel. That was the first time id ever seen it done that way but it makes since when parts get wore. It ran better but ended up just needing a valve train rebuild.

On the carb im not real sure. Im more of a efi guy. Sounds like you need to talk to a parts guy. Take it up and have them take a look and see what they say on the choke and rebuild kit. The rebuild kit should be cheap and easy. The 4b would be an upgrade for sure but not cheaper then fixing what u have. I would consider any 2b a weak link but im a hotroder . I guess since it has a 2b that its a 305 motor. They say .045 on the plug gap.
