Anyone ever rebuild your own carb?
I have a 750 Carter AFB Competition Series which needs revamping. I have ordered the kit, and am planning on doing this myself with the help of a Carter book. I'd appreciate any pointers any of yall could send my way regarding carb rebuilding in general.. Thanks.

I've done a few. Now I send them out. I still have a Qjet in a box full of parts that I "rebuilt".

In general, give yourself a clean well lighted work area, lay out disassembled parts in oder of removal, bottom out mixture screws counting number of turns in, don't bend any linkage, make notes as you go to ease assembly, clean everything with a good carb cleaner and blow off with compressed air if possible, follow instructions carefully. You may want to replace the floats while your in there, and don't forget a new fuel filter.

I've rebuilt my little 2bbl Rochester. Take plenty of pictures, and don't let the dog into the shop. My dad's german shepard pulled the drop-cloth with all of the linkage parts on it right off the work table onto the floor. I was PISSED...

The AFB (carter/eldebrock) is so simple even a chimp can do it.
Take your time, and a digi cam is priceles on this kind of stuff. |

I'll have to see if the wife lets me use the kitchen table as long as I cover it up good with cardboard and plastic. I have a digicam. Why would it be so helpful? To take pictures for reassembly? Thanks.............

Absolutely. For me it helped with the linkage once it ended up scattered all over the floor because of the stupid dog.
You never know....better to have pics then need some and not have any.

I used to be able to rebuild rochester 1 bbls and q-jets blindfolded. Back in the early 70's, when I turned wrenches for a living, it was far cheaper for a mechanic to rebuild a carb than to by a factory rebuild. As long as you start with a good body, you're okay. Problem with rochesters is the pot metal body, the shaft holes wear to fast and need sleeved. Edelbrocks and Holleys have far better bodies.
The q-jet that came on my 69 was worn out. I threw a kit in it after I dumped a tablespoon of Oklahoma clay out of the bowl. Problem was that the clay had sealed up the leaky shafts, it now is in a box and I put a Holley on the truck.

Yeah, rebuilding a edel/carter carb is pretty easy.
One suggesting. Don't get carb cleaner in your eyes...it REALLY hurts. |

I'll second the carb cleaner in the eyes thing...OUCH!
Also, I don't recomend doing it in the kitchen. If you use the Berryman's Chemtool The B-12 stuff, it'll get your carb nice and clean, but the whole house will reek for a month. As a matter of fact, if you use that stuff, get some real thick rubber gloves. Your hands will stink for a couple weeks and the wife won't let you touch her. (very bad thing) I say digi-cams are awsome becouse you can take a picture of every little thing you dissasemble, and not have to pay 20 bucks to get the fil developed. Then, if you have any ? at all on the re-assembly, all you have to do is find the immage on your PC. |

I have a Qjet carb, before I rebuild it. I went to our locat pick-a-part paid a dollar for admission and I took apart a few of their carbs. I didn't buy anything but it sure helped rebuilding my carb.

Another thing that might help you is go to wal-mart or something and buy a cookie sheet or brownie pan or whatever they call them. get one with a pretty good edge on it, bigger is better. Tear your carb down and reassemble on the sheet. That way no parts get lost and you have a nice clean, portable surface to work on.

AFB style carbs are pretty simple. Even q-jets are simple to take apart and put together. With a Q-jet it's knowing all of the little tricks about bushing the shafts, sealing the plugs and just plain evaluating the core for rebuilding in the firts place. It takes losts of experience to set a Q-jet up to run good as well. I've rebuilt about 30 carbs in my life. An AFB was the easiest, A Toyota was the most complicated and the Q-jet was the worst to make run well. I just paid a guy 200 bucks to build me an electric choke Q-jet. He is an expert and it was worth every penny.

I rebuilt the carb on one of my old VW's, and I don't think I'll do it again. It ran ok, but stuck open the first time I floored it. If I do try it again, I'll just have to remember to put some plastic on the seat before I punch it for the first time.
