Fuel mixture adjustment will only effect the bike at idle. If you still have the points on your bike there is a chance the problem is there. I couldn't get rid if a stumble, kept thinking it was in the carbs, until I changed over to Dyna electronic ignition. Could also be a vacuum leak ( O-ring like you asked about) or Sticking carb slides.

Unless you have changed something on the admission/exhaust sides of the engine, or it has always had this problem, I doubt changing the fuel/air mixture is the correct cause. Assuming you have not changed the exhaust, etc recently and that it didn't do this in the past, it is far more likely that the carbs need a good clean. Changing the fuel/air mixture ratio is probably just covering up another problem (like dirty carbs) not fixing the real cause.
