Stromberg BXVD-3 Power Jets

[Ed McDermott]

Hi, I am trying to correctly identify the part reference for the two power jets in the Stromberg BXVd-3 carburetor on my 48 Dodge Custom D24 with Fluid Drive.

I have a leaking carburetor and I believe the cause may be a bad power jet in the accelerator pump path. 

The figure below shows the 2 power jets marked 55 and 56 respectively from the carburetor.  The manual states #54 for both.  I believe the jet marked 56 maybe bad as the center pin on it does not return above the top surface as the #55 does.

Looking on line I don't find jets with the #54 or 55 or 56 number.

What is the correct part ID for the jets and does anybody have a recommended source?

Thanks

Ed

Your BXVD-3 accelerator by pass pump jet... drill #56 is the correct . 

Stromberg part #P24062.

Also the pin on that jet is supposed to stay down below the jet top surface.

   Your power by pass drill #55 jet is also the correct jet and size. Part # P23676.

Pin stays up above the jet surface.

thank you very much.

I am trying to find the cause of gas leak, mechanic says its from the accelerator pump.  Not sure of the cause.  Have new kit installed with new accelerator pump.

Thank you again.  I noticed in the exploded parts assembly drawing you provided that there is a lower pump  spring showing.  The dodge manual does not show this spring but the carburetor rebuild kit does.  My carb does not have one and the kit does not include one.  The accelerator pump does not easily return upwards so I had ordered some springs based upon the physical size of the pump shaft end and the well size .  Maybe this will work.

Thank for all the information.

After a lot of testing, I was able to demonstrate that the fuel inlet valve  was not closing tight under the normal fuel pressure from the fuel pump.

Reset the float lever and  replaced the fuel inlet valve and problem solved.

Thanks again
