1972 carter quadrajet
I have a 1972 corvette convertible with a carter quadrajet carb with numbers that start with the number 3 and one with the number 6, it is a 350ci 200 hp engine. Any help the car sat for a long time before I purchased it and running it with new gas it has failed and leaking gas. Should I rebuild this carb or replace it.

What's the entire number? There are a lot of Carter carbs that start with the numbers 6 and 3. Most Carter-built Q-Jets in 1972 started with "42XXX". You need to post the entire number and date code to determine what you have. Are you sure it's a Q-Jet and not an AFB or a Thermo-Quad..?

I rebuilt my Carter after it sat for 16 years. Worked ok for about 30 miles then the floats started sticking (or something like that, gas pored into the primarys) I just went ahead and bought a Eldebrock and threw it right on, fires up with no issues. Did want to keep messing with the old pitted carb.
