This is to "pay forward" some help I received. Earlier, I posted a thread "Can't get no (flavor) satisfaction w/ eGo". I was getting a "burnt wick" taste from Boge LR cartos and CE-2 ceramic cartos. Following some advice I received, I tried thinning out my juices by adding 15 drops Distilled Water and 15 drops pure PG and then filling with my usual juice, the 3ml "walk around" supply dripper bottle I usually carry. No more "burnt wick" flavor, at least so far. So what was happening was that the juice couldn't flow to the heating element as fast as I was vaping - I'd get one, maybe two, decent puffs, then the next puff tasted nasty because the heating element was starved for juice. Maybe you're having the same problem, and if so, try thinning out your juice with water, PG, or even PGA. In my case, I used about 30% thin-out (3mls is about 100 drops, and I used a total of 30 drops to thin it). Of course, this makes the flavor weaker, too, but it'll tell you whether you've got a viscosity problem or not. Then, in the future, you can order your juices with more (or completely) PG, and less (or no) VG, to thin them out. You can always get VG at Walmart, if you want to thicken up your juice at home.
