Hi fellas. The accelerator pump shaft / bore is pretty worn out on my Rochester 2GC (1965 Pontiac 326) . It's pretty floppy in the bore and I have a bit of stumble when I crack the throttle because of the slop, threes a lack of innital fuel squirt. Do you have any suggestions for a repair, or just buy a new carb top and shaft? My hunch is that the pot metal carb top is probably worn instead of the steel shaft.
