I'm going to need a replacement Carburetor for my car, it has the stock quadrajet 4 barrel on it, any suggestions on what to replace it with??

rebuild it on a Saturday after reading up on it in the sticky's above and searching on "Naf's" rebuilding thread

Mrgref92

ok well the only thing wrong with the carburetor is the choke, it's bad, and i have the same exact carburetor but the threads for the fuel line going in are really stripped, so is it possible to take the choke off of the other carburetor and put it on the one thats in the car?, thanks

no problem

Mrgref92

Ok well, I tried to replace the choke, and after i did, everything on the carb went wrong, gas was everywhere. so unless someone can get the fuel inlet threads back to normal, i need to go with a different carb. if i do will a 1405 edelbrock work? thanks

a new brass fitting (fuel inlet) is ~ $14.00 plus shipping. look at part number 370 on this diagram. is tht your part?

No the thing that screws into is stripped

is that the fuel line or the main body of the carb itself?

Mrgref92

the main body

You can get a fitting that has slightly larger and self-tapping threads to repair it. You do need to have the carb disassembled so you can clean out the debris generated in the tapping process.

I'll probably get a new carburetor, will the 1405 edelbrock go on without problems?

hi , i have a 1405 from edelbrock with the electric choke , i like it and is simple to install and adjust.the car runs great with it...but look out!! the edelbrock haters are coming!!

Mrgref92

ok, well I was thinking about going with a manual choke, they arent hard to do are they?

matj1990

not to steal the thread but what in the #@% is rong with a edelbrock carb ????

No.

List of problems:
1) Won't bolt to the intake manifold.
2) Fuel line won't fit.
3) Need a TV cable geometry corrector.
4) Need a vacuum/mechanical advance distributor.
5) It will cost more money to put it on than it would to make one carb out of the two you have.
6) SES light will be on all the time.
7) It isn't legal for street use in any of the 50 United States.
8) It's a downgrade from the q-jet.

well, i have no problem with edelbrocks ,,but i think if you can rebuild your Q-jet then you should,,,but if you want to put in the 1405 edelbrock go ahead ..it is your car afte all!...you will have to slightly change a few items , but edelbrocks are easy to install and run fine if adjusted correctly..go to edelbrock.com and see their installation tech videos...really easy and helpful,

mooch1

no , they are easy to install provided you have the right intake/adapter to install the carb on....the electric choke just needs a power source from the fusebox..it needs current to power the electric choke from when you turn the key to "on" from your fusebox accessories...then adjust the fast idle and a few other things..like i said go to edelbrock.com and look at their tech videos ,,they explain it all real easy.

i agree with mooch1, there is nothing wrong with edelbrock carbs. however 57kid has a point in saying that you probably won't pass an emissions test and won't pass a visual test with it. but if those items don't concern you i say go right ahead. And to answer you matj, 57kid and several other members don't like the edelbrock carbs, sometimes i wonder if they think god created the ccqjet on the seventh day.

mooch1

well i agree with you too, edelbrocks are fine ,, this is why i said the edelbrock haters are coming! beware!,,there are some people who love them and then there are others who hate them..i recently went from a holley to an edelbrock and i am happy with it ..but some people here on these posts think that i should confess my sins or something..to each his own!! we are here to read and learn and share opinions ,,but if some people don't like something , doesn't mean we all have to hate it too..

He wants a manual choke. Don't think he's worried about 'downgrading'.

I tapped a new fitting on one while it was installed. Plugged the fuel outlet (to bowl) inside the filter housing with vacuum tubing then blew it out when done.

I agree with 1 thru 6 and 8, but 7 is wrong in ohio anyway

#7 is correct, even in Ohio. It's Federal law, not state or local.

Mrgref92

Wow a lot of responses, umm to five7kid can you explain on your 3,4 and the manifold on the engine isn't stock and i have an adapter so should it go on?, and right about now anything is upgrading because the carburetors dont work and country carburetor said it would cost 300$ to rebuild, and I could get a new one for 300$, and the fuel line won't be a problem I'll just run a new one, but are manual chokes hard to adjust? thanks

The TV cable to the transmission will require a special bracket in order to be installed on a different carburetor. The geometry (distance cable moves vs. throttle opening) is extremely important in operating the trans properly.

The stock distributor is controlled by the ECM which requires input from the stock computer controlled carburetor. With the carb removed the stock dist will be in limp mode and will also need to be replaced with a mechanical/vacuum advance dist.

If you have a square bore manifold and an adapter for the spreadbore q-jet you may be able to install either type of carb. Carb height may become an issue with some if the adapter raises it too high.

Manual chokes won't require much in the way of adjustment but there's little reason to install one on anything larger than a lawn mower.

Mrgref92

ok i'm still not sure what the tv cable is, but the distributor won't be a problem because I have a vac. advance one. so your saying I should go with the electric choke?

naf

The TV cable controls the transmission. There should be, at most, three cables attached to your throttle linkage. Throttle cable (connects to pedal near right driver's foot), cruise control cable (has a long slot in it where it connects to bracket) and the TV cable which goes to the transmission. The TV cable bracket must be set up so that it moves out a precise amount as the throttle is opened. Aftermarket brackets are available but they'll add to cost.

Yes electric chokes are advised, especially since you already have the wiring right there.

It was not on the seventh day that that miraculous qjet was created. Took some time to make something that perfect.

Mrgref92

Ok well my car doesn't have cruise control so on the quadrajet I have the throttle, and a cable that attaches to the bottom of the linkage, thats the tv cable?

naf

iTrader: (7)

Yes. Add up the cost of the new carb, new dist, TV cable bracket assembly and then review the sticky on alternate means of controlling the torque converter lock up.

Mrgref92

Does anyone know where I can get the plastic O-ring for the quadrajet rochester carb, that goes in the fuel inlet so you dont leak gas? I really need one.

Parts store should be able to help. It may come with a new filter.

Check out Guaranteedcarbs.com I haven't used them yet but another member on here recommended them and said he was very satisfied.
