I have a 64 cutlass convert with 330 engine. In an attempt to ID the carb for a rebuild kit, the only ID numbers on it are 22998. The carb is a Rochester Quad. Does anyone know where I can find a rebuild kit for this carb? Thanks!

 

Was just looking up the 64 Q Jets. The carb should have a number that starts with 70XXXXXX. Check on the left side of the body by the linkages.

Is this the original carb for the car?

 

don't know if it's original. The owner passed-away, and the family did not know much about the car...except that it has been sitting for 25+ years.

I checked over the carb, these were the only numbers I found. Embossed on the carb is "4 Jet", and on the opposite side "QUAD". Appreciate your help!

 

Kind of wondered about that. There are rebuild kits for the Q-Jet and the 4 Jet. Is your carb manual choke or automatic? Also look at the throttle body (base) to see if it's aluminum or cast metal. That could be helpful determining what kit you need.

Any chance you could post pics of the carb from all angles, and the numbers you're describing?

 

Unless it is afrom a later model, it is a Rochester 4GC, isn't it? I don't think Q-jets were used until 1965 and even then, not all models got them.

 

Correct. 1966 officially started the use of QJets in Olds. Prior to that, and on 2-bbls thru 1967 I think, the carb number was on a little metal TAG secured to the carb at an air horn screw. Not the most clever plan ever, as the tags get torn off or lost most of the time.

Do you have such a tag??

 

It could be a 4G or a 4GC. That's why I asked if he has MC or AC. You're right the the QJet was a 65 start. I was wondering whether the OP was confusing 4 jet with Q Jet. The number he posted is not close to any references I have for those carbs, that's why I asked if he could post some pics.

 

Al, I have pics but site will not let me attach them!? If you wouldn't mind emailing me and I'll send them to you. ken422@sbcglobal.net. Thanks!

 

Your pics are probably just too big for the server. Here's something I put together for folks who run into the exact same problem. Try it first and if it doesn't work I'll get them from you and post them.

* clik the 'go advanced' tab
* Press the icon that looks like a paper clip; and A 'Manage Attachments' box will appear
* Choose (navigate on your computer to where the pics are stored) and hit 'open'. repeat for all 5 pics.
* Hit 'upload'. It may take a bit of time depending on your pic resolution. If you have ultra high res, you will have to 'resize' them with your picture editor to a 1024X768 size or smaller for the C.O. server to accept them.
* Close the "manage attachments' box.
* Preview your post and the images will be at the bottom
* Hit 'submit post' and the thread will have the images installed at the bottom. Unfortunately you can only do 5 pics at a time this way.

If you have the pics hosted on another web server?
* Copy the IMG url and Press the icon that looks like an envelope with mountains on it. Paste the URL into that box and hit 'ok'. You can install up to 20 images this way.
* Be sure to preview your work.
* Make sure the images don't carry on across the page, stack them for easier viewing.

 

Allan, hopefully this comes through, thanks for the info!

 

Allan, here's extra pics!

 

Isn't the only difference between a 4g and a 4gc the 4gc has automatic choke and the 4g doesn't.... Just curious ...Tedd

 

Tedd, that's my understanding too.

lass4ken: check on the front of the carb too for the numbers. I think it should be one of the following:
7024154 (California), 7024050 or 7024051 (AC equipped car)

Here is some more info that might help you find the numbers. From the looks of the carb it will need to be sprayed with carb cleaner to find them. http://www.carburetordata.com/?id=7

 

Allan, thanks for your help! I'll give your advice a try and see if I can find anymore ID numbers. I appreciate your help! Happy Holidays!

Ken

 

This is the tag that would ID the carb.

CIMG0688.jpg

 

It's from a 64 Cutlass with a 330.

 

That's what appears to be missing on the one lass4ken has. So chances are good it's a 7024050 or 7024051

Putting the I.D. tag on the carb is akin to putting the engine number on the heads.... anyone can remove them and then you've lost some important info on the car. Thank you for posting that tag info. I've seen those tags 'for sale' on fleabay.

So this kit would probably work...http://www.ebay.ca/itm/CARBURETOR-RE...ht_1684wt_1024

Also at O'Reilly's
http://www.oreillyauto.com/site/c/de...2447&ppt=C0359

 

No such tag on my carb...but thanks for the info!

 

Or it could be 7024054

 

Here's what the Rochester carburetor book shows for the 4GC Oldsmobiles for 1964:
7024050 - big car; no A/C; not CA
7024051 - big car; with A/C; not CA
7024054 - 330 engine; auto trans.
7024055 - 330 engine; synchromesh trans.
7024153 - big car; with A/C; CA delivery
7024154 - big car; no A/C; CA delivery

This number would appear on the tag as shown previously. Commercial rebuilders almost always discard the tags. Custom rebuilders are some better on this subject.
Your photos show the presence of a vacuum break control assembly. This is correct for the 7024054 and 7024055, but not for the others.
I can't find anything on the 22998 so far. The book shows a part number of 7023093 for the vacuum break, if that is where it came from.
Without more information, this is as far as I can go.
If it is a 7024054 or 7024055, the Rochester overhaul kit number would be 7016451; the "OK kit" would be VFR-510; the gasket set would be 40-309.
Kits for these carburetors should be available from many aftermarket sources. Here's one: http://shop.advanceautoparts.com/web...carburetor+kit
Shop around.

 

The 22998 is actually 22995 if you enlarge those pics. Thanks for the great info sharing!

BTW, which Rochester Carb book do you have? The one I have Is published by HP Books and authored by Doug Roe & Bill Fisher - published 11/73. Could not find that info you posted in it anywhere so I'm obviously interested in a better reference book if you could post the title/author etc I can get one for my 'library'.

 

That 7024054 tag was on a carb that was from a 64 Cutlass with a 330 and AT that was being pulled for a sbc. I believed the carb to be original to the car but could not confirm it.

One of the members here has the carb, intake , air cleaner and valve covers. Another has the block and crank.

 

The "book" is really a 3" thick binder containing many bulletins from United Delco. It appears to be a GM sponsored item through UMS (United Motors System). It includes Rochester carburetors from all GM divisions and others which used Rochester, at times, as Packard, Jeep, marine, & some trucks. It has information from the 1930s to the 1970s (most of the details are from the 50s, 60s, & 70s). It shows all individual component part numbers, adjustment values, rebuilding procedures, and long out-of-date prices. If you do things with Rochester carburetors, I recommend it. I have attached some photos of it. I apologize for the photo quality. Almost everything was dark, and the flash wasn't cooperating.

 

That thing looks like a Parts Catalogue! If you ever decide you want to get rid of it LMK.

 

that is an early edition of the number 9 book. the bible of rochester carbs.

they got bigger over time...

your carb is a 7024054, it is the second build because of the white round disk. This was a change mid year.
