Factory type is the only one I've ever been able to keep tight, I even tryed a GYTR one and it want stay in, I think theres to much of it that sticks out of the bottom of the carb. and with vibration they just want stay where there supposed to?

Get the r&d fuel screw. It's spring loaded and attaches to a screw on the bowl. The adjustment is located up on the side of the carb. I have one and will never go back to a straight one. There only about 35 bucks so not that much more than a standard straight one that is 20 bucks plus it will never fall out.
