My joker has 510 threading, and for some reason the 510 catomizers won't screw in, they wiggle back and forth, and I push down hard on it when I try to screw it in, and then I try to screw the little piece that is on top of the joker to move it up the cartomizer threading and it still won't screw in and stay. Just wiggles then falls off. I am trying to get my liquinator on here but dang if it will go on! I have managed to get a boge carto on, but it sort of goes in a bit of an angle, and then sits on the top of the joker slightly to the left. Do you think the threading is gone on it? Can this be replaced? First my omega goes, and now my joker. So now I am vaping my liquinator on my 510 passthrough of all things, and it looks a little silly. Anyone know what can be done?
