Ive got a rochester B single barrel that came with my '58 235, its a manual choke. I have gas leaking from the throttle butterfly shaft. I searched, and found some great threads saying the float or needle / seat. I adjusted the float so it sits way below were it should be, and it still leaks. I checked the needle and seat and don't see any clogs or anything damaged.

I just rebuilt this carb, and besides the sporadic leak, it runs great. Anything else I should attempt? My budget is so overblown I'd like to avoid buying a new carb if possible.
