carg suggestions

I have a 1982 Pontiac firebord S/E, 305 HO with the original CCQ-Jet. I've recently found out that the Carb is going bad. Is there another CCC available for my car other than the Q-Jet? Or, is it more practical to rebuild the original carb? Any suggestions are appreciated.

Thanks

There is no other CC carb available. Rebuild it or get it rebuilt or get a rebuilt replacement.

What exactly do you mean by you "recently found out that the Carb is going bad"?

Five7Kid;

My car just quit on me one night while I was driving it. I attempted to start it in a normal way, and nothing. I finally pushed the accelerator to the floor, and tried starting it. It did, but it ran rough at idle, and would not idle on it's own. It's a good thing I was close to home. It ran fine while driving, but would not idle smoothly. I took it to my mechanic the next day, and he told me that it was dumping gas real bad, and would dump more if I continue to drive it. He adjusted the idle so that it would idle at 10K RPMs, but recommended that I replace it as soon as possible. I'll be doing that soon. I have a 86 bird (which I totaled in DEC 2001) with a 350, and a CCQ-Jet onboard. I'll just pull it, and install in the 82 bird. I'm holding the 350 until the 305 dies.

Thnks for your comments.

Sounds like a simple float seat problem. Probably has something stuck in it.

You might try this before taking the carb off: Remove and plug the fuel line at the carb. Start the engine, and run it until it dies (fuel bowl empties). Put in a new fuel filter while you're at it, hook the fuel line back up, and start it again.

When something is trapped in the float needle, the fuel level rises and the float just pushes harder on the piece of debris in there. When you do what I suggest above, the fuel bowl drains, the float drops, releasing the grip on the piece of whatever. When you hook the fuel line back up and start it again, the float has dropped all the way down, and the rush of fuel in will wash out the piece of debris (hopefully). Then, the float can operate correctly again. Whatever was trapped in the seat will just sit harmlessly at the bottom of the fuel bowl.

I have done this on a couple of occasions. Eventually, you'll want to disassemble the carb and get it all cleaned up. In the meantime, this will get you by, and may help you diagnose the problem.
