I ordered some new Atty's from Bruce, they will be here in a few days. I'm not completely sold that it is the attys, I think it might be "operator error" I just came across your instructions in English for the AVS system, I have been vaping with the CR completely open. When I would get a dry hit, I would open the liquid a bit more. I'm going to try a different approach, as It starts to get a dry hit, I'm going to close the CR a little more. So far it seems to be helping.
I think by vaping with the CR wide open, and only adjusting the juice (since I chain vape) I am opening the liquid control too far, and when I set it down and don't draw on it every few seconds, gravity takes over and it gradually drains into the CT.
So far so good Imeo! It hasn't done it yet today too me
