Looking for advise, every time I fill a brand new carto, it taste horrible. A combination of burning and something. It is unbearable at times and it sometimes wears after 20 30 puffs, or until it i refill again. I filled a previous used one with RY4 last and it was bliss, so smooth and tasty. So I was wondering what I'm doing wrong? Is there a break in period? Someone suggested that I may not be filling them enough to start, although I put 20-25 drops in until the juice will sit on top of the filler and then let them sit for a few. I've heard of primer, but thought it was regulated to atty's. Can someone give a noob some pointers?
