That is weird,never had a dry hit on this and it is all i use now. I have one with 50 VG/50 PG and the other running 90 vg/10 pg. All i use is Koh Gen Do cotton.I wick really sloppy ,just put it through the coil and trim to edge of deck.Stuff it down then tuck in at the bottom.I did not think you could go wrong with this tank.I chain vape on the 90 VG with no problems at all.Maybe if you do not tuck in where it touches the deck at the bottom it will block off the juice holes? Good luck,i am sure it is something simple.
