I've been using E-Cigs for a year. I decided, after much research to try my hand at building with a kayfun. I kept getting a burnt taste. I'm at about 1.6 ohms using silica. I know it was wicking fine. So...I became suspect of the silica. I've always primed it before using but I tried torching/dry burning a never used coil with silica before I fill the tank. It smokes heavily (even after at least 10 seconds after torching/dry burning) and even caught fire. And the burnt smell is the same that I taste. What are your thoughts? Am I right to think this silica is suspect or could I be doing something wrong? I bought the silica on ebay. I'm using a Vamo V5.
