Carter WCFB Vacuum Piston

Carter WCFB

It isn’t unusual for the vacuum piston on the WCFB to become frozen in the cylinder where it resides. Be careful when removing the top of the carburetor that you don’t force things and break the piston lever. When the piston is frozen you may have to drill a small hole in the bottom of the float bowl, just under the piston and hammer it out. Use a brass drift punch. The piston is brass and can be damaged very easily. Once you get the piston out, clean, Carter WCFB Vacuum Piston the cylinder so that the piston move very free up and down. We use a small bottle type of brush and spray silicon spray into the cylinder while we clean. The vacuum piston is no longer produced and can only be found as a NOS piece, or used. You may even have to resort to finding a used WCFB carburetor.

  1. I have a 1953 Hudson Super Jet. The carb on it has WA-1 on the side. Once removed, the bottom is stamped 972 on one side with the S on the other side (Sides being the bolt holes). Is this such a carburetor? If so, what did it come off of. Hudson never used those casting numbers that I can find. Thank you for any help.

    • The WA-1 had a tag attached to the top of the carburetor. Without the tag there is no way of knowing what the carburetor number is, or what it fits.

  2. I am looking to replace the hot air choke on the wcfb which is on a Buick Century 1956.I want to use a manual choke and not an electric conversion.Do you have the kit to mount to the carb body?.I already have the cable ready to go.
    Many thanks.

    Aidan Cullen.

  3. as for as I know the correct manifold for a 1956 chev with 2×4 is 3731394 I seen one for sale number Manifold # 3739653 I believe it your with two carbs. What is the difference between the two number what is 3739653 (for what car). I m looking for the complete set up

  4. I have two 2317S WCFB carbs on a Chrysler 354 hemi.These would have been from a first series 300. Were both identical, choke and all? I only have the choke guts in one carb and there is no place to mount the coil in the housing. If only one has a choke, I imagine it would be the primary…rear…correct?

  5. I looking for a accelerator pump for a 55 chev belair 265 v8 4bbl wcfb. Top plate number is 6-1098.
    I bought a kit that had a pump requiring a spring and clip on the pump which did not work.
    The pump I need is a solid shaft, 2 inches long with a 5/8 leather cup.
    If the pump in your rebuild kit # 632 meets these dimensions, I will order that kit unless you have a pump by itself that meets the above dimensions.

    • I’m afraid individual pumps of that size are not available. There are some I just cannot buy outside of the kits. The kit 632 does meet your criteria.

  6. Can anyone tell me where I can purchase a secondary Vacuum diaphragm for my Carter WCFB 4 BBL which is on my 56 mercury?

    I am in Australia and its impossible to find here?

  7. I’m looking for a Primary shaft with throttle lever for a WCFB 1-1579.
    If not just the shaft, what about the complete case base? (WCFB 1-1579)

  8. I have 2 1955 Chevy WCFBs. One has a 1020 top and the other an 1147. Are those both Plymouth tops? Do you have any idea what a 1274 top belongs on?


    • I’m not sure which plugs you are referring to but if it’s the cleanout plugs, or expansion plugs, then they will need to be removed and replaced (if you have any), and/or J.B. weld applied to them.
