Re: 100% newb to the carb scene

If not bad gas, could be some additive in the new gas reacted poorly with residue left by the old gas. Was it ethanol gas or real gas?

Might pull the vacuum line from the metal line to the transmission that goes to the manifold vacuum port and inspect for fluid. If it is dry there, probably not sucking fluid.

One thing I have found useful to do on my 1405 Edelbrock is to occasionally clean the power pistons in the carb. With the engine cold, pull the air cleaner. On top of the carb are two small hex head screws holding down two small metal plates. One on each side. Loosen but don't remove the screws. The plates should lift up. Pivot them out of the way. Under each is a small piston and needle. Lift each out and spray both piston and cylinder with carb cleaner. DON'T lose the small springs. Use lots of cleaner. Spray, let set and spray some more. Wipe off the piston. Reassemble.

While you are at it, check ALL of your vacuum lines.
