Update:
I have taken apart and cleaned my carburetor again. The flooding issue turned out to be due to the float valve being damaged. The original needle and seat had been replaced with a float valve that uses a rubber pad that pushes against a seat rather than a needle. This rubber pad had been badly damaged (I’m guessing it got pushed against its seat too hard by the guy who rebuilt the carburetor) - picture 1 Because this had been damaged I chose to replace it with the needle and seat from my parts carburetor(I think it came off of a Hudson from a similar year) rather than reusing the original 2 piece needle and seat. -picture 2 I also decided to replace the original fuel screen with the one from my parts carb as this one was much cleaner (it was slightly different in that the original one had its top folded in but the spare one has both ends open) -picture 3 This ended up fixing the fuel leak problem, not sure about my other issue where the engine shuts off after just a few seconds of idling. It was getting too dark to see and I could not find my keys.

I am fairly certain that the cylinder heads are interchangeable however doing so would change the compression ratio

I am currently using a regulator with a fuel pressure gauge both brand new so I am confident in the accuracy of my measurements. I will also double check and re clean out any dirt when I take it apart again in a few hours. I will come back with an update once I do these things.

Like I said there is a brand new needle and seat- maybe I got a bad one? I will try blowing into the inlet again to double check but I’m pretty sure it held in the past. I also have a spare float from my parts carb I can throw on if needed.

Ok I will try hooking it back up to the original combination pump and see what happens. I have rebuilt it already but I was going to use the electric pump up until the engine had broken in as it was already there.

I’m having a couple problems with my carburetor on my 1948 Packard Super Eight it has a Carter WD-0 model 643S.
The first issue is it won’t stay idling. I can start the car pretty easily, but then it idles for about five seconds, and then shuts off. Timing is currently set to 6 degrees before TDC The second issue that I have is gasoline leaking from the float bowl. I have tried turning the fuel pressure down to below three psi. I have also tried putting the float level way lower than where it should be. Whenever I turn the fuel pump on, it will build pressure up to just below three psi (or wherever I have it set) then it will slowly leak past the needle and seat, causing the floatbowl level to rise until it spills out the top, where the accelerator pump is. I have just had this rebuilt so it has all new gaskets, needle&seat, completely cleaned, etc. Could someone with more experience help me out here?

I remember seeing that about a year ago. I was wondering the same thing about if it was related to the concept car.

I am happy to report that after reinstalling the oil pump in the correct position and advancing the distributor as far as it will allow; I now get a spark on cylinder one at exactly 6 degrees :)
I also cleaned up my distributor and have new points, condenser, and rotor on the way! Thank you guys for your invaluable help once again.! I should now be able to start the break in process. Well after I get my radiator re-cored…

Ok I will plan on fixing that today if I can. I had a sneaking suspicion that was the problem because that was the only part of the ignition timing I didn’t personally do and I imagine it can be pretty easy to mess up.

Ok I will check on that because it doesn’t feel “springy” like the other distributors I’ve dealt with, if fact I didn’t even realize it had centrifugal advance, I just assumed it was all vacuum as this is the e oldest car I’ve worked on. Any ideas on what might be causing my spark issue previously mentioned?
