It is possible that you could have flooded the carb when you adjusted the air/fuel screw. I would keep the screw where it is at and let the scooter sit for a while to let the fuel disperse. Once the scooter has sat for a while, keep trying to start it and it should start up as long as the screw is adjusted to the same location that it was in the last time it was running correctly.
