  1. hello, i have a 9605s….has been gone thru and all new parts…
    a couple of things are going on …before it was rebuilt it would not fire up..just sit and crank….so we did the rebuild…got it to fire and the motor would die or back fire spitting raw fuel every where…and the fuel would leak out of the throttle shaft…
    i then set the floats to exactly 25 down from horn and gasket ….
    7/16 with horn upside down….
    now it wont fire at all…..sits and cranks again….

    not very familiar with these carbs, they seem to be very easy to work on …
    not sure what the issue is , nothing seems to be clearing the problem…
    do i just have a bad carb…?
    thank you

  2. Mike, do you have rebuilt carburetors ? Looking for price on Carter ETW1, primarily used during the 40’s in military vehicles.

  3. I have a 9400S carb on my buick 231 V-6. It has the marking L1 to left of 9400S and i was wondering how to identify what the L1 is? My friend has a C2 9400S and he was wondering the same thing?

    Thanks in advance for any help?

    Also i am missing some linkage for the other side of the choke rod – opposite from the choke side? I think it hooks to fast idle stop? or some other name? How can i buy or where can i buy thes linkages, i dont know the bends or sizes or i would make them.

    Any help would be appreciated.

  4. I purchased kit #1128 for wcfb 2444s Chrysler carburetor. The gasket between the air horn and float chamber had gasket material over the floats. The gasket in your kit does not. What is the purpose of this extra gasket material, splash guard? Why is your gasket different?

    Also, the screw in seat for the needle and sat has a standpipe on the secondary side. The manual says this is to prevent sediment from entering the needle area. The needle and seat in your kit does not have this? Please advise.

    Where can I find the factory jet specifications so I can determine if they have ever been changed? Will need this for 2445s also.

    • Sorry for the delay. I passed this along to one of my carburetor consultants for his comments.

      As far as the gasket goes, the difference isn’t that unusual. It could have been a design change along the way, or some companies idea of a better design. Keep in mind that the kits being produced today have not had the same design for many years now and they have worked countless times as they now are.

      Here is the comment about the other concern.


      The customer is correct: the standpipe on the secondary needle seat actually passes through a circular debris screen with a hole in the middle. That debris screen ensures that no dirt can get into the needle seat orifice . . . but of course the fuel had to pass through the cylindrical screen at the front to get to the rear of the carb (except on Buicks) so the secondary screen is rather redundant.

      Eventually Carter quit building them that way, and current practice is to do as the factory did: simply to leave the cylindrical screen nearest the fuel inlet in place and do away with the secondary screen and standpipe-type needle seat. And no, it would do no good to install a cylindrical screen in the secondary position; the incoming fuel would bypass it completely.

  5. Hello and thank you for your site and videos! I have a ’73 318 dodge with a 2 bbl Carter bbd carb (i believe). i have just rebuilt it but car will not start and fuel actually flows out through the very top of carb after several seconds of turnover. What would be causing this???


    • Did you test, or replace the float? It could be leaking and if so it would not close the needle & seat thus letting in too much fuel. You may also have set the float level wrong. At any rate for whatever reason, the needle & seat is not closing. Could be that some foreign matter got into the needle & seat keeping it open.
