Danimal77, I'm guessing your using a kanger dripbox??? If so the extra build deck is the one you just put in, and giving you problems. I have the 60&80W and both extra decks coils where not preheated, and I had to pull the cotton and preheat myself. Hope this helps.It was just the premade coils that came in the kit. I'm using the same juice and battery. So I'm really not sure.
