Should I rebuild carb?

[Jah]

I noticed today, the first day i actually got to take my car out and drive it around more than five minutes, that this thing is eating gas. I know g bodies aren't great on gas, but this was ridiculous. I looked at the carb and its dirty and looks like it hasn't been cleaned for years. So, would rebuilding the carb help a lot on gas mileage? I've been looking up how to tune it but I wanted to know if rebuilding it would help more than just tuning it.
I've never done this before, but I'm sure i could figure it out with all the websites ive been reading. Also, if I should rebuild it, where can I get a good kit? I've heard the ones at advance auto have sub-par materials.

The rebuild kits at NAPA are the best ones i've used.

Ok cool. How long does it take to rebuild a carb on average? This is my daily driver so I really can't have it out for long. And I dont have money to keep paying all this money for gas :shock:

Is the carb computer controlled?

I don't believe so... There are no wires going to it that I can see so I'd say no.
As you can tell, I'm no mechanic. I also start work tomorrow and would love for all my money to not go into gas or labor that I could follow directions and do myself.
Its on a Chevy 350 engine, not sure about transmission. But the way that thing is drinking gas is ridiculous. Hopefully rebuilding this thing will help. I'll go get the number off the carb and post that in a second, just incase it would be any help.

EDIT:
It is a Rochester DualJet 310.

I used Guaranteed Carburetors to throw in a new rebuilt carburetor. It might be better to get one that is already rebuilt rather than attempting to rebuild it yourself if you don't have any prior experience. They aren't cheap, but a lot cheaper than buying a Holley Carb.

I don't have the money to buy a new one, yet. But when I get the money, I'm going to buy a new (suggestions?) intake and a q-jet to replace this dualjet. So for now, I'm trying to get as good gas mileage out of this one as possible. In two weeks when I get my first check, I might go to pull-a-part and and see if i can find a q-jet there.
This is my daily driver so I want a good gas mileage. I also want a little extra power... But gas mileage is more important at the moment.

Tired Carb

Hey, give Greg, of Sparky's Carb Service, a holler. He's a top-knotch carb rebuilder. He did the Q-Jet for the '69 Olds 350 in my '78 Cutlass. Check out the pictures on his website of carbs he's done for customers...

What kind of mileage are you getting? What condition are your spark plugs, wires, dist. cap and rotor in? All these things can contribute to poor fuel economy. Why is it the first time it's been driven in a long time? Different wheels and tire sizes, as well as a potential trans or rear end swap can result in an inaccurate speedo, so if you keep track of your mileage via your odometer, it can throw off your calculations.

Try spraying it down with some carburetor cleaner or Seafoam and see if that helps.
