Ugh! My Kayfun lite plus air control screw is acting as a lock, since it must have worked its way down closer to the top of my Panzer. It is now stuck in the recessed area of the 510 connection(the radiation symbol.) It is only allowing me to turn it about a quarter of the way off from being flush. The gap is very small. I tried to get a 1mm precision screwdriver in there. I was only able to get it in there a tiny bit. I am kind of at a loss as to how to get it off the mod. I don't want to mess with it too much as it is pretty full of juice. Every time I try to force it to unscrew beyond the stopping point, the Kayfun tank starts to unscrew. I'm planning on vaping it dry before I do any serious work on it. Any suggestions?
