need carburetor for my 71 New Yorker 440

[Yogi]

Help. I need carburetor for my 71 New Yorker 440. Someone put a modern Edelbrock in it, but apparently it didn't fit and that did not stop them from bending every lever and changing every attachment point to where it idles very fast, very slow, the pedal sticks and sometimes won't come unstuck. I think this should have had the AVS carb but not sure. Does anyone know of something I could use? Any help is appreciated. Thanks.

Sounds like you need new linkage, not necessarily a new carburetor. What model Edelbrock is installed? I have an Edlelbrock on my ‘71 300, 440. Also the factory carb stored. I can take a look and give you the name and model as soon as I make it to the garage.

If the carb is an aftermarket AVS2, there is an adapter piece to mate the "Chevy linkage" on the carb to the Chrysler linkage on the car now. At least before it was altered.

There are some good illustrations of the carb/transmission linkage in ANY Chrysler FSM of that general model year. That adapter piece makes everything work (as designed) as Chrysler used the Holley 4160 and Carter AVS (originals) kind of interchangeably with the same linkage items. Just the aftermarket AVS/AFB Edelbrocks need that adapter to hookup "as stock".

I forget the adapter part number in Edelbrock, but it is usually listed along with the Edelbrock AVS2 and AFBs in the Summit Catalog, in the "People who bought this also bought this . . ." items.

With the adapter, you re-use the existing throttle linkage stud.

You might also need to chase some OEM return springs, too.

DO please advise of the AVS part number when you can.

When all of the linkage is re-configured to what it needs to be, the automatic transmission throttle rod will need to be re-adjusted, too, most probably.

The AVS 2 is a good carb but they are known for internal adjustment issues (there are threads bout this on FABO) and like all Edelbrock's, they need the correct throttle, and transmission kick down adapters and some a tweaking to make them work properly. There are many threads on A, B and C Body sites about these carbs. Here is a good one from FABO with Edelbrock adapters for linkage, throttle, and transmission kickdown. 2-Barrel to 4-Barrel Conversion

Okay I took a look. Right now I have an Edelbrock 19069 avs2 annular boosters 650cfm electric choke - that is what the box says. The original carb is a Carter AVS. Numbers on the carb are: 6 2020 next to copyright and registered trademark symbols. Let me know if you need photos of anything.

Thank You for the prompt response.

IF the AVS was an original Carter carb, from the factory, it would have a number like "4732S" stamped on one of the front corners of the baseplate. Rh side?

If the car came with an AVS on it, all that should be needed is the bolt-on linkage adapter plate (to the AVS2) and to transfer the existing throttle stud into the adapter bracket. Then, everything should line up perfectly.

1971 440 350 horse is a 4966 AVS.

I do not have the original carb......just an Edelbrock that says "Edelbrock" on a red label, a number 8867 and the word "Weber" cast into the side. The linkages are a mess and everything is bent or missing. I need something else as a fresh start. I have the '71 FSM, but it obviously doesnt tell me which aftermarket carb to use here, some 55 years later.

Great! I just placed the order with Summit. It should be here in 2 days. Thanks for the info, guy.

Thanks for that additional information. The FSM will only specify what came on the car from the factory, not what the aftermarket claims will fit the car now. That will be from the current catalogs of Edelbrock and any re-seller of their carburetors.

Remember to get the Edelbrock 1481 throttle adapter.

I ordered that, too---Thanks

1966 Chrysler would have a AFB.

I recently installed a new AVSII 650 with electric choke on my 69 Imperial. I had the original Holley 600 rebuilt a couple of times, plus various fine tuning adjustments.

Yes, I would recommend to double check the factory float settings etc., and purchase the tuning kit with various rods, jets and springs. Changing the carburetor was one of the best things I have done to my car. I am very pleased so far. If you can replace the damaged factory throttle parts I believe you may be surprised how well the carb works.

 

[Rubatoguy]

Here is a photo of the base of my original carb. I can't quite make out the number, but it looks like 4966S I can't make out what is in front of that.

Make sure your throttle valves are not hitting the intake manifold bores. Most carbs need the correct thickness base gasket.

 

[CBODY67]

^^^^ No matter the model year, I have had my best results using a factory-style heat insulator base gasket (with the plastic or metal bushings in the mounting stud holes). Which means purchasing the OEM-style gasket for a 1970 AVS Chrysler Corp engine application. With an electric choke, no problem anyway.

As I have usually adjusted the factory linkage from the choke thermostat, those adjustments are no issue to me.

Just MY experiences. YMMV.
