It cant move because you have a left hand and a right handed thread working against one another . Turn the atty to the right it moves down . If you turn the adjustable grub screw to the right it will do the o posit . The only time the adjustable post in the 510 moves a little is when you remove your atomizer . Hope that helpsIt is. I waited until the change was made and he retrofitted the retrofitted mods before ordering one with the new 510.
Why wouldn't tightening the atty cause the screw to rise? If it's making contact with the positive pin on the atty, and that pin is moving clockwise, why wouldn't the screw move clockwise with it?
