I've had Ken rebuild two of my carbs. Did a great job. Even advised me against doing work he didn't think was needed.

I had Danny Sarvis (70WCars) rebuild a Q-jet for my 71 98. It ran so much better than the POS Summit carb I have now. He hasn't been active in years but you might try sending him an e-mail though his profile.

Where are you located, I have an awesome guy that does carbs here in the D

Eightupman (John Herald Jr) on ClassicOlds has a great reputation and he just spent about 15 minutes on the phone with me talking me down from the ledge on a carb that I bought from a reputable q-jet rebuilder. It wasn't running worth a crap and I couldn't get a hold of the rebuilder. John walked me through the basic settings and I was able to tune it in from there. Some of the settings were so far off I never would have been able to figure it out myself

Burd

You can also send it to cliff in Ohio. He can flow bench test it, re color it, has all the parts, or can hop it up for you. anything you want to pay for. Lol

DO IT YOURSELF!

I rebuilt the quadrajet on my '78 Toronado. Second time I've rebuilt a carb. First time was the two-barrel on my '67 Delta 88. It's really not difficult, will save you A LOT of money (just the cost of a $20 rebuild kit), and you get a lot of satisfaction in doing the job yourself. And you can do it in an afternoon, not wait the weeks or whatever to get it back from a rebuilder.

People find the prospect of rebuilding a carburetor intimidating and seem to think that rebuilding one requires some kind of magical skill, and the professional rebuilders want you to think this so that you'll pay their several hundred dollar fees. But rebuilding a carburetor is not like creating a painting or any work of art. There's no "judgment" involved. You just disassemble it and reassemble it with the new parts in the kit. Not much different from fixing a broken table lamp. Just more parts. Then make the necessary adjustments when it's on your car. It's not complicated, and there are lots of video to show you how to do this as well.

I found this video be very helpful. I actually had my laptop computer on the workbench and would pause the video as it went along and as I did each step.

Dang, I can’t believe how many still do them. Lol

Quadrajets are very versatile carbs. They were used on a variety of engines, and up to 500 cubic inch engines. Some consider them dinosaurs, but they can be performance tuned. Many people don't understand them and opt for an after market carb. There wouldn't be as many good "performance rebuilders" out there, if they were as bad as many people infer.
.........Just my two cents worth.

Jaunty: Good point. I agree you can rebuild yourself. Not that hard to do. I have done a few over the years and they ran fine. However, I would personally spend the money on someone who can set it up exactly and re-bush the throttle shafts. After this many years, the throttle shaft area gets worn on these old carbs and potential vacuum leaks. You can buy a kit to rebush it yourself but I would rather pay someone who can drill it exactly straight, etc.

all that being said, I have heard good things about both Ken at everyday performance in CT and custom rebuilt carbs in NJ.

Burd

There is a guy in Burbank Cal, BFIC. He’s had rare carbs on the shelf ready to go. If your looking for a certain number. Call Carlos.

While we’re on the topic, this guy was at the TA natz a few years back, I picked up his book, I thing he quit printing it already, I can’t find it on line, it’s good for the swaps. It lists a lot of carbs. Lists what it’s for, even service replacement and marine. If you got a carb laying around and don’t know what it’s for, let’s try it.

If you enjoy turning a wrench, rebuilding your Quadrajet is a good option.

matt69olds

Rebuilding one is no big deal. The problem comes with re-calibration and repairing 40 years of wear. Usually there are some changes that need to be made to the tune for today’s gas, and to compensate for engine modifications. That’s when it’s nice to buy the kit from a Q-Jet specialist, not only will they have the special tuning parts, but the quality is probably much better than your 20 dollar parts store rebuild kits

rickw30

Matt69olds is correct.
Doing it yourself is no big deal. It's knowing the tricks that important. I used Cliff Ruggles for my 70 w30. I have rebuilt it many times throughout the years and finally decided to let Cliff do his magic.
It was very reasonable and a fast turnaround. He incorporated all the tricks and the carb looks and runs perfect. He was a pleasure to deal with.

Schurkey

A high-school kid can rebuild (clean, and put a kit into) a Q-Jet. A talented kid with some guidance could rebush the throttle shafts.

The problem is RECALIBRATING the carb. THAT takes far more talent and experience than a "rebuild". And most folks aren't equipped to re-plate tarnished parts to restore the "new look".

If the carb isn't being recalibrated--just returned to stock calibrations except "clean and properly-adjusted", there's no reason you can't take this project on as a weekend project. When practically every car on Earth had a carburetor, lots of carbs got rebuilt with aerosol carb spray to clean 'em, and a parts-store "kit" of gaskets and small parts.

TODAY I'd want one of Cliff Ruggles' accelerator pumps at minimum, but his entire kit would be nice. His pumps will survive E10 fuel, and some others won't even though they're advertised as "Ethanol safe".

While you're at it, get Ruggles' book on Q-Jet carbs, and a copy of Doug Roe's book on Rochester Carbs including Q-jets. Heaps of good info in both.

×2 did a custom tune on a 78 403 carb that wouldn't idle. Years after I had him build it, I had a weird choke issue bending linkage. He sent me parts free of charge. He is a Buick guy but currently owns a 84 Hurst/Olds he is fixing up.

Bought a Quadrajet from Quadrajetpower.com about a month ago and I would not recommend them. Had too many issues for as much as it was. A carburetor from a reputable builder should not have a stuck float, loose bolts, or a secondaries that have not been adjusted to open completely...

Warren Seale

I've use Cliff Ruggles as well for the carb on my 72 W30. He is a big fan with the Pontiac guys. That was over 15 years ago and all is well. But I've heard that when he gets backed up there can be as much as a 12 month wait. I recall at the time it took about 30 days to have mine rebuilt.

Would any know what could cause WOT on a Rochester Quadrajet 4 Barrel?

tru-blue 442

Pushing the go pedal to the floor.

synoptic12

* What if accelerator "Jams" while accelerating, and WOT occurs, then what is the cause?

tru-blue 442

Return spring on backwards?

tru-blue 442

I see you edited. Sounds like it may have a few strands of broken throttle cable internally causing it to stick.

synoptic12

*I would not know. The Rochester was rebuilt by a carb guy over fifteen years ago. It is highly unlikely that the return spring is on "backwards". The Rochester has worked for fifteen years and still works. Had WOT occur and it was not any event to be left for the weak. Do not know squat about carbs, just the basics. I just shifted in neutral and gunned the accelerator to kick it back down which worked. Someone said to shut the motor off or you could blow the motor. Any assistance here is appreciated.
Cleaned the exterior housing and everything is normal at the moment. Do not wish to be in that position again.

synoptic12

* I've heard that before. The throttle cable looks good to the point I can see, no broken strands. Thanks much.
What do you mean 'internally'? If it were the throttle cable, what would replacement cost be?

tru-blue 442

If that ever happens always just shut the engine off and pull over. What your describing sounds like a bad throttle cable to me.
What make and model car is this?

synoptic12

* Thanks very much. I was concerned as to shut off the vehicle going about 60, I would lose the power steering. I have a 1986 Oldsmobile Cutlass Supreme Brougham, 307 C.I.D. Vin Y. What is the cost of the throttle cable, repair cost and could it be anything other?

They are relatively easy to change out. You could possibly U tube it to get an idea. Also, yes you would lose
power steering and your power brakes with the engine off but you can power through that with a heavy foot and strong arms.

synoptic12

* That is the specific reason I did not shut the ignition 'off', due to possibly losing control, especially in traffic. Could I shut the ignition off and shift into Neutral and start in Neutral? What I did was move the gear selector into Neutral, gun the accelerator and then shift back into Drive which worked. Is this method o.k.? Hesitant to believe that it could be a throttle cable whereas the causes are not really related to a frayed throttle cable which it is not. Some points of a bad throttle cable pertain to cruise, rough idle etc. but I do not know. I'm not touching the Rochester, rather have someone look at it, if I can find someone. Thanks very much.

synoptic12

* I'm familiar with Parts Geek, has some excellent prices. However, I'm not touching anything on the Rochester, just not my forte. Thanks for your input.

Schurkey

IF (big IF) the throttle was WFO, and you threw the shifter into neutral, the connecting rods came out of the block and you drove over them. And the crankshaft.

I'm guessing the throttle was not WFO, at least not the secondaries if the engine survived running at no-load.

synoptic12

* Could you place that synopsis in terms I can comprehend, WTO? Are you saying that moving the selector in Neutral could damage the connecting rods and leave the crankshaft damaged as well? If this occurs again and I shut the car 'off', how do I restart in traffic going about 70 m.p.h.? Thanks very much.

"I'm guessing the throttle was not WFO, at least not the secondaries if the engine survived running at no-load" > 'Please elaborate in terms I can understand. Thanks very much.
