Leather is/was the preferred choice. The cheaper rubber cups became the norm. You could see if a deathanol friendly rubber cup is available.
All I have ever used in my carter AFB is the leather pump.
Mack, can you share with me where you sourced the correct leather pump?
Edelbrock SB your source for a new replacement accelerater pumps for the Carter or Edelbrock carbs
They are basicly the very same carb --as Edelbrock bought the rights to manufacture the Carter carb
There is a slight difference in the size of the carbs total venture area ( total carb top opening is slightly larger than the Carter )
The stock air cleaner will require an adapter if using it -- or use a replacement after market air cleaner for improved air flow to the carb
Thanks guys! I actually have the Rochester carb (should have mentioned that). I wonder if the leather pump will work on the Roch........I'll call and ask.
I'm also trying to drill out the choke tube of my intake manifold. I purchased a new choke tube from Chip on Ebay, but I also need the spiral piece that fits inside the tube. Any ideas where I can source that? I emailed Chip as well and waiting to hear back.
I remember seeing one somewhere in the parts shed. Email me and I will locate it. firstname.lastname@example.org
I do not know the carb you have very well myself so someone with more experience with that carb should chime in
The leather accelerator pump— I know —was for the original Carter carb from my own experience
The way that carb came from the factory
