The rear carb on my race car has an air leak audible at idle that I would like to correct. The leak appears to be around the shaft itself. I pulled the retaining nut and washer off the shaft. The shaft ball bearing fits tightly in its' bore. The diagrams I have all show a "dust cover" of some kind outside the bearing. A spare carb has one. But the carb I'm using doesn't seem to have any room for anything outside of the bearing. My question is....am I missing anything that would be designed to seal the shaft other than the bearing itself. I would assume that re-greasing the bearing might help? Am I missing something?

Could be. Although this is the first time I've had the carbs apart at all. It never leaked before in the few years I've owned the car. Do you know if the leather seals are still available? If not, I assume I could make something easy enough?
