Several years ago, a friend with a BMW 2002 (also made in the 70's) had a 3-year running battle with CARB and the CA DMV because he got a replacement carburetor that wasn't OEM. Even though its emissions were within specifications, they didn't want to accept it. (He's a MechE and had little sense of humor about the large price differential.)

Unless the case is cracked or something, if CA is still being a stickler about engines from the 70's, it might be worth finding a rebuilder. If they're anywhere, they're in CA or the Carolinas.

What carburetor do you need?

I see some Carter carbs. on EBAY but they are not cheap. Might be best if you rebuild your old one or check the web for carburetor rebuilders but first look for the model # and maker of carb. My guess its either a Carter or a Holley if its a Holley it has a LST# on top of the horn of the carb. not sure where the # is on the Carter carb. Its getting harder to get parts for 50 year old vehicles and if you can they want TOP DOLLAR.

Take pictures of your carb along with engine size and take it to a carb shop in he LA area. There’s got to be at least one or six carb shops in all Of LA. They ought to be able to identify it and a. Rebuild it or b. Know what can replace it and where to get it.

Have you tried doing the rebuild yourself? Kits are pretty easy to come by and the rebuild itself is not that difficult if you are somewhat handy.

I rebuilt my first carb on my father's Oldsmobile when I was about 10 just using a Chilton's manual. Nowadays you've got countless videos on YouTube to help as well.

Here's just one of many places to start your search for the carb rebuild kit: https://www.carburetorfactory.com/kits_dodge.php

There are many carbs that will interchange but it will take some mods. While Rock Auto Parts may have the exact one needed, they will most likely be a remanufactured version. Most Chrysler products that I worked on of that vintage had a Carter though a few had a Holley. You do need the part number off either the original tag under a top cover screw or on the top casting.


I would probably be looking at a new Edelbrock or Holley rather then a reman and do the mod work needed to do the installation.


https://www.rockauto.com/en/catalog/


https://www.edelbrock.com/shop/carbu..._list_limit=30 (I like these better then Holleys as they are a super simple, Carter design)



https://www.holley.com/products/fuel...s/carburetors/ ( Great carbs but can be finicky for best performance)



To adapt, you will need to (most likely) to move or midify the fuel inlet line, add or modify the transmission kick down linkage or cable and modify the throttle pedal linkage. All are fairly easy for someone that has a few tools and a DIY attitude.

I'm gonna guess its a Carter "Thermoquad". They were actually kinda difficult for most folks to rebuild. Had a black plastic center.
There is a number stamped on the back of the baseplate that you go by.
If you look up that # you could more than likely just get one online.
Pictures would help a lot.

Great help

Let me first start off by thinking each and every one of you that's given some input and insight into this matter second this is an update the carburetor was rebuilt already but it's too broken or at least too much that the gas goes into the spark plugs so they try to rebuild it twice it's a holly carburetor is just no good so I'm looking for a new rebuilt carburetor for the same engine that's where I'm having the trouble

Holley carb on a 79 Dodge chassis , I'll have to assume your engine is a 440-3.
440-1 would have the T'quad.
Also assuming this is a Class A coach .
Last year the engine was used .Dodge had a huge overbuild of the chassis , and got in trouble with government for re-doing serial numbers and selling off the chassis as 1980's .

The big questions are; does the fuel system need to be original and is the chassis subject to emissions testing in CA. ?

If a Holley, 4 barrel look at the number stamped on the front of the air horn (where the choke is mounted). That will give you the current part number though maybe not the OE part number.


A Holley, if it's kinda gushing gas and fouling spark plugs, that usually means the power valve has failed. These easily fail via a back fire. There is an easy fix for this besides a new $12 power valve. Holley sells a check valve kit (~20) that you install after some minor drilling work with the supplied drill. Also, these occasionally have a float that sinks, usually the brass versions. They are relatively inexpensive too.



As Twinboat said, a fuel injection mod is nice but way too expensive as it is a LOT more complicated then unbolt a carb, bolt on a new one. You need a new intake manifold, EFI unit, a control system and a fuel tank mod for a high pressure pump along with a new gas return line. Cost wise is when all done $3K plus --- and why my '31 Ford street rod still has a carb

You just said everything I wanted to say and more. With the part number he could just call Holley and ask about a direct replacement. They have improved a few things over the years. My 72 LT-1 Vette now has a new 670 Street Avenger carb.

I would also think that there should be a good carb overhaul outfit in SoCal.
Need to find out what Holley you have and get on the phone.
