76 ADFA Choke Pull-off Diaphragm replacement

Post by SpiderCake »

Howdy all,

I'm on my second 32 ADFA rebuild, the first went smooth but the choke pull-off diaphragm that came with the rebuild kit was too small for the housing. I found a diagram with webber part numbers for the 32adfa but the diaphragm is showing as not serviceable. Image shows the size difference.

Suggestions?

Thanks,

~SC

the diaphragm you have in the picture is the power valve diaphragm from a 2000 carb, the choke pull off one has a longer shaft made into it that ll the rest of the assembly goes on, some of them come assembled.

Description says ADHA, but it looks right for the ADFA.
