im working on a 66 426 hemi the accelerator pump on the rear carb is junk, it will only pump on the last half inch of the stroke.. i feel the spring is to weak and absorbing to much of the movement.. i got one off amazon (from china) junk, its rubber and just wont work either..what is everyone else using?

run a screwdriver lightly around the perimeter between the spring & the inside of the leather to expand it slightly

The Edelbrock accelerator pump doesn't work in some of the Carter main bodies. I'll look tomorrow and hopefully I can find the card of the business that I found who has the correct pump for the Carter carb. I was going through pumps like poop through a goose until I found this company. The one I bought from them is over two years old and working like a champ.

Try putting some motor oil on it and run a small thin round drill bit gently between the inner surface and the spring to spread it out scope up

If that's the place out here in Washington, that was the guy I use. Can't find the car, but that sounds correct. Damn filing system of mine is pretty crappy.
