Carter AFB
Accelerator pumps available to me locally are either too old or too small and won't make a decent seal in the bore despite soaking in oil and/or gas. I don't know if the bore is worn out or maybe I am not getting the correct pump. Anybody have any thoughts?......Bill

Will the pump from an Edelbrock Performer fit?

It isn't likely the bore has worn that much. It is possible the wrong pump is being used- Carter used 4 different accelerator pump diameters- 5/8" through 3/4" in 1/16" increments. And there are different lengths.

There's a chance it may be missing the spring that sits under the bottom "skirt" of the pump piston that holds the bottom edge out against the bore, if it is really close to fitting, but not quite. In this case, it would pump fuel, but just not well. And IIRC, not all pumps used that type spring.

Tip- Be sure the S-link to the pump is installed so that when viewed from the front, it looks like a correct "S", not a backwards "S".

they are both a weber carb. cause back in the day if you pulled top off a carter AFB or AVS it said in the fuel bowl made by weber for carter an you look on the side the edelbrock carb says weber on it!

Give this guy a call, he is an expert in all things Carter and has rebuild kits that actually fit.
