I'm at a loss, was all nice and clean, slowly checked I was doing everything right, made sure to add liquid to coil, put it together carefully to make sure it was all right, left it for 10-15 mins then slowly primed it starting from 10w making my way up, as I got to about 25w I could already smell the burning and when got to 30-35w I knew it hadn't worked.... could the tank be faulty? I'm seriously at a loss here
