It's been a while since I've had my 4GC apart, but IIRC it's like most carbs of the era,i.e., there's a well under the accel pump seat that is sealed with a pressed-in & staked plug. Drill out the plug and punch out the accel pump ball from below. If the seat is deformed, they a bigger OD ball is called for (there are specialty carb shops that have 'em). When done, seal the old well plug with an aftermarket (same shops as above) screw/press-in plug. Problem solved.

P.S. The accel pump probably still "worked" because it can get fuel from the float chamber IIRC through both a slot and pin hole.
