On the old Carter AVS's and AFB's they were. On the Eddies- not sure.
This much I DO know- the new Eddies use some plastic/fiber/rubber assembly for the accel pump. The old carters were Brass/Steel with a Leather seal. I wouldn't trust the new ones for ANYTHING! I've not tried the new ones in an old carb, but I just don't like the design of the new one's at all. Looks WAYYYYYY too flimsy to get the job done. Might be a contributing factor to the new Eddies getting such a bad rap.
Anyway,
I'd buy a rebuild kit for an old one just to get the old-style accel pump.
Try Mancini Racing for a rebuild kit for you old AVS. They normally stock them, and they are the correct kit.

Enjoy!
