When you do jetting, fuel screw has important part in that. It is very hard to adjust with out opening that hole. You need to take float bowl complitely off. I'm not sure but I'm almost willing to bet that those screws which has fell down has been Zip-Ty. Problem with those fuel screws (yes, I have one on my table top) is that material in that O-ring doesn't take heat very well and hardens up and shrinks. Then that O-ring can't do it's job. Another thing that causes fuel screw to fell down is that it is opened too much (over 2 turns) you should change your pilot to bigger one if you have it opened more than 2 turns.

Now it should never fall out if adjusted correctly as mentioned above but if it does it and the tiny o-ring, washer probably won't be lost.
Before you remove the screw (stock or aftermarket) stuff a clean white rag under the area below the screw. The three parts I mentioned are very very small and easy to loose. If you lucky, they will stay on the screw, if not they will fall on the rag. If they drop onto the motor or ground they're pretty much lost. Maybe even get a few replacement o-rings before you pull it.
