Post subject:  Carter BBD questions

These were removed from slants but Im not certain that at least one is not a 318 carb, according to an on-line reference the number 0-2543 that is imprinted on the side is a V-8 carb and both carbs appear identical.

Admittedly I have found these on-line carb look up references to be misleading to say the least.

Just looked up the second carb number which is 0-2681 and that is also showing on-line as a 318 carb.

What gives are these slant or V-8 carbs.

How can I tell the difference? Where can I reference the #s on the carbs to get a definitive answer on original application?

One does still have the red metal tag on it and I will clean that up to hopefully read it and pull some more numbers. ........

I am going to copy and paste this useful info I found whilst searching for information so that I can have it for future reference...................


Once upon a time there was a red or green stamped aluminum tag that was screwed under one of the float bowl screws that gave the specific list number for your carb. This appears to be missing on your carburetor. If you are ordering a rebuild kit you should be able to get a generic Carter BBD kit that has all the gaskets you will need. You will have to be careful to match up the gaskets to the holes in your carb body though, since the kit will come with many extra gaskets for all variations of the BBD ever made.

The BBD does indeed have a fast idle cam and screw. They are on the driver's side of the carb and attach to the choke butterfly. Yours is clearly present in the first picture you posted. Do you see those two small screws that are behind that big screw on the side of the carb? The big screw is the screw that holds the fast idle cam on. The outboard small screw is the curb idle screw and the inboard small screw is the fast idle screw. See the odd shaped piece of metal held onto the side of the carb by that big screw? That is the fast idle cam. There is a rod that connects it to the choke butterfly which also appears to be present on your carb. When the choke closes that rod should pull the cam counter-clockwise, placing the inboard smaller screw on one of the steps of the cam. As the engine warms up, the choke opens, the cam rotates clockwise, and the screw move down to a lower step of the cam and eventually stops contacting the fast idle cam altogether. If your carburetor does not give you fast idle when it is cold, you need to adjust it.

The large circle with vacuum lines coming out of it is part of the EGR system. That is the EGR vacuum amplifier if I am not mistaken. If you have disabled the EGR valve than you may remove this device and the mess of hoses attached to it

Here the metal tag which came off the carb who has the screw lying next to it in the above photo.

It reads 8137s and then 3277 819

And here is another informative post............The number on the brass tag attached to one of the carb screws will be 8136S,8137S,8177S... among the numbers... the throttle plates will have no holes drilled in them (like the 318 carbs), and the choke plate unloader has a different form than the 318 version...

Sounds like they are both slant carbs than cause no holes drilled in throttle plates...is that right?

I was curious what BBD and BBS stood for..........Ball & Ball Dual Barrel.......(Ball & Ball Single Barrel...........

Carter Carburetor was established in 1909, and lived through 1985

Hi 1930.
If you go to the FAQ in the engine section, open the link Carburetor operation & repair information, you'll find the link to the Carter BBD operation and repair manual. From page 26->on in that manual, the differences between the 318 BBDs and the new for '77 SuperSix BBD are described in detail.

If you open the link to the Carter carb manuals with jet and metering rod sizes in the engine FAQ, and open and browse the Chrysler_Carter_Carb_Manuals_65to79.pdf, you'll find the numbers for the Carter carbs. They are not always placed in logical order, so you may have to 'leaf' through some pages until you find your tag number.

The same engine FAQ also lists a Chrysler service training video for the new BBD for the SuperSix engines.

Thank you Olaf. I plan to print out the Carter manual but I was going to ask before doing so if that particular manual was the closest version I could get to my own particular carb.

I learned with the 1945 I had previously that there were many different versions and so much of the material I was able to save and print did not pertain to my own carb.

Ive tried to view the video but cant get it to open on my comp. I still need to try and open it on my wifes computer.

Bent PCV fitting=slant Also the air horn is thicker on the flat side than a 318 carb.

Good score!

Did you snag the intakes? :shock:

Yes I did, would you happen to know where I can get specific specific information concerning how the carb was originally set-up internally? Id guess that info might be found in a factory service manual but at this point thats only a guess.

A rebuild kit will have all the specs. All the ones I have didn't come with the tags. Lucky you! More than likely the top is warped. Mine get a ride on the stationary belt sander. The throttle shaft will probably need to be bushed.

I think he is looking for the internal technical specs, like step up spring tension rating, manual vs. auto transmission, jet sizes, metering rod diameters, etc….

For those numbers you need a Carter carb book that lists the specs for each list number. I have one of those books for Holley carbs, but not for Carters.

I have the Dave Emanuel Carter book. That stuff isn't in there.

Theres been a couple links posted in a thread that I started about a week ago titled "timing chain?".... matv91 posted them, doesnt get specific on what spring/rod/jet combos came in wich vehicles (im assuming because the variations could be endless depending on climate, elevation, vehicle weight, gearing, trans, etc...) but does list sizes and numbers...

Also due to the differences in fuel today vs fuels of yesterday, experimenting with different combos may be very useful rather than try to mimick what chrysler did 30+ years ago...

He helped me realize that my carb (reman with out a tag) is a 78-79 with a set up for a manual trans cars, but with a heavier spring under the step-up piston and accel pump the carb now responds very well to my wagon with an auto trans and tall gears... Just food for thought! :D

Hey Reed, I thought you was familiar with the engine FAQ! :D

Look up Carter carb manuals with jet and metering rod sizes which leads you to:

Chrysler_Carter_Carb_Manuals_65to79.pdf

There you'll find a detailed parts list for each Carter used on Mopars from '65 to '79, and the corresponding carb model number for each year and type of engine, according to the attached tag. From the parts numbers, you can also determine which model number that should have been on the missing tag. The title 'manual' is a bit misleading, it should really read 'parts list'. There are no drawings, only text. The engines and years are not necessarily in the order you may expect, so you may have to leaf through a lot of pages to find 'your' carb/engine combo.

A similar parts list for Carter carbs used in non-auto Mopar engine applications, is also linked to in the same place.

I dont know if anyone else is having the same issue, but that chrysler_carter_carbs manual link doesnt work. Tried at home, tried at work, tried from my phone... Maybe its just me but it would be nice if it did work lol!
