The diaphragm is now installed and it started almost on the first try. I accidentally knocked the distributor off timing when installing the B manifold. A quick turn back and it fired right up. I runs OK but I need to fine tune the carburetor a little better.
I'm finally on my way to running a B manifold with hopefully a more reliable carburetor.

I got the diaphragm the other day. It's an NOS part which I feel I was lucky to find and at a very reasonable price. I wasn't sure if it was the right one but I felt it was worth a risk at the price.
I bought the last two he had after confirming that it was indeed the right part as spares.
I'm going to see if I can put the carb back together tomorrow and get the car running once again.

I was going to reuse the old shaft with a flat diaphragm if I hadn't found the right one like I did. The only problem is that the old shaft uses a spring loaded cap (56) for whatever reason and that would have made it a bit of a challenge.

I got lucky yesterday and found the correct diaphragm for my carb. I'll see how it fits when I get it and I may buy a few extra for spares as these seem to be very hard to find.

While on the subject of 4100's I have some 65, 66 manuals and they say there is a check ball in the secondary vacuum passage that prevents the secondarys from opening prematurely and the 1.08 carb I was running apeared to be missing this ball, I then checked 4 other carbs I had here and 2 rebuild kits from napa along with the instructions and they did not have this ball nor do the parts break downs show this ball in their kits. Instead they had little restrictors in the passageway and the kits do not come with the little balls. When did they change this secondary feature?

Thanks Jim. I'm glad they have dimensions so it may make things a bit easier to check. I'll give them a try.

These folks seem to have a better selection of Accelerator Pump Diaphragms with long shafts. It might be worth a call.

I also tried to copy and paste the image directly from their site which appears to work. COOL!

That looks like the same carburetor as mine. It's interesting that I contacted Mike's Carburetor and  they didn't offer the suggestion to just get the regular diaphragm, which they sell by itself, and use the rod like they show in the video. They only wanted to sell me the whole kit. I think that's a little dishonest on their part.
Thank you for the suggestion Túlio.

Is the carburetor the one with the check ball instead of the umbrella valve on the accelerator pump??
if so, I rebuilt one for a friend's '57 Ford, and used the regular diaphragm. The kit came with a little extension (just a little metal rod) to be used in that particular model of carburetor.
You can get a regular diaphragm, and cut a piece of the rod from your original part and use it as a extension.

This guy is rebuilding the exact same kind of carburetor, and using the extension I talked about!!
