I got my zenesis 2.2 just over a month ago. I have used it with 4 wraps of 26 gauge since day one. Earlier today I was noticing my button was getting very hot. I broke everything down cleaned with alcohol rebuilt using 3 inches of #400 mesh rolled up properly and thoroughly oxidized. 4 wraps 26 gauge still hot. So I try now a third build using 27 gauge 4 wraps button is still hot as could be. What gives how could a type of build that worked multiple builds over a month suddenly cause a hot button? Thinking about it some more. I may be getting my wick flooded and maybe firing It longer than I use to and that is why i had not noticed it as much. Just tried a spring from another mod and the brass screw in the switch still got hot using 27 guage 4 wraps what gives.
