Hey vapers, new to the forum; but not vaping. I'm using a Smok Alien 220W TC Box Mod with a Smok TFV8 Baby Beast and a Quadruple Core coil inside. I swapped out my coil a couple of days ago, primed it, filled the tank with liquid (70/30 VG/PG), and let it sit for about 30 minutes and started vaping; everything was fine until yesterday when I started noticing a warm flavor on 45-50 watts (what I usually run.) I was smoking a cigarette waiting for my batteries to charge right before this happened. I took slower and lighter draws, until I could only do about three seconds before the taste got horrid. Today I've been running 40 watts, and it's the same thing, but it's getting to the point where I don't even want to inhale any vapor for the fear of the taste. It's a brand new tank, I just changed the o-rings, the coil isn't burnt at all. I have no idea what the hell is going on. Somebody please help me!
