Hot Rods ID carburetor

I'm trying to ID a carburetor built by Carter for GM- it is a Quadrajet carburetor # 7035530.

I need to purchase a rebuilding kit.

Thank you in advance,
Mike

 

Early 1970's Q-jet and the number you need to get the kit is the one that goes around in a circle. It's not a Carter but a Rochester....

 

That's not the carb I.D. number---it's just a casting number for the main body. The I.D. number shoud be stamped vertically on a flat pad about 2/3 of the way back on the driver side, or if it's a really early carb, on a rould dime sized tag that's pressed into a recess towards the front of the driver side (that sometimes falls out).

 

Hi,

I need to ID this CARTER built for GM QUADRAJET carburetor so I can purchase a rebuilding KIT.

My dilemma is that it DOES NOT have the ID # stamped where it should have one.............but then, it appears that other similar carbs did NOT either.

WHERE THE NUMBER GOES........IS BLANK-



ONLY NUMBERS STAMPED ARE ON THE OPPOSITE SIDE..............

 

the 703... number is the GN number needed to get the right kit at any parts store... everything will be the same as the Rochester equivalent. Carter was a small-scale alternate supplier, I believe as a backup for strikes and disasters... look up the hydramatic fire.

 

What (if anything) is STAMPED (not RAISED as the number in your picture) about 2 inches to the right of "Mfg. by Carter..."?

After close look at the pics....
order a kit for a 74 chevy 1/2 ton with 350 engine.
divorced choke, and throttle linkage are the clues..
As Bruce says, the rochester q jet kit will work just fine.

Took it apart today.............getting closer.

My understanding is that if the air-horn has 9 screws and 2 screws instead of 3 down in the primary, it is NEWER than 1967.

CAN ANYONE CONFIRM THIS?

Looking at some rebuilding kits on the internet............I figured this carburetor would fit: 1965-67 Chev; 1966 Olds and 1967 Pontiac.

I sure would like to know for sure what this came off of..............

If you furnish an email address, I would be happy to share all of the pictures of the carburetor dismantled.

Thanks a bunch,
Mike

 

Are you looking for a 67 carb PM sent

 

The throttle arm is definitely Chevrolet, and the '65-'66 carbs had a strange secondary lockout arm across the rear that yours doesn't have, so I'd say it's from a '67 Chevy. All of the '68 and newer carbs I've seen had the I.D. number stamped vertically from bottom to top 2/3 back on the driver side; only the first three years used the press-in circular I.D. tag. Maybe they stopped that when too many of them fell out.

 

THANKS TO ALL.................

I NO LONGER need assistance with my carburetor. I must be getting OLDER than I thought. I finally located the number and right where it is suppose to be.
I have a 7028212 A8 DH carb and have started the rebuilding process already.

Thanks again,
Mike

 

The "roll stamp" on the 1968 and newer carbs was necessary to comply with Federal smog emission requirements. The carburetor is considered to be a component of the smog emission system. Thus it was necessary to have a permanent identification number so the wrong carburetor was not "accidentally" installed on a smog engine.

In the FWIW category, the 1965~1967 round tags have a punched round center hole for Federal carbs, and a square center hole for California (1966 and 1967) carbs. Also, all of the round tags are color coded to the application.

And Mike, glad you found the number.

Well, I guess that's one advantage to emission requirements.....at least, forty plus years after the fact, we can tell what the carb came from! i think that every garage used to have a full time employee whose job it was to make sure that the triangular I.D. tags that came on 2GCs, 4GCs, and WCFBs were all removed and thrown away before the car was returned to its owner.

 

He also pulled the tags off Ford rearends

 

This well may be true.

However, a more likely reason for the missing tag on a carburetor is that at one time in the life of the carburetor it was rebuilt by a commercial rebuilder, and sold through a FLAPS. The commercial rebuilders "group" many similiar carburetors together, and sell under one "rebuilders number". To keep the customer from knowing what they purchased, the rebuilder removes the tag.
