I filled the DCT by filling the tank a bit more than 3/4 and then filled the cart. When I draw on it I get a gurgling sound which I think means I got fluid into the cart hole -- is there a way to get that fluid out? It also seems like I'm getting a bit of juice leaking. I'm getting a lot of vapor and throat hit, but it's got a bit of a burnt taste. I tried putting on an 808 cartomizer and it works and taste very good. Could I just have a bad DCT? Is there a recommended voltage to use with the twist with the Smoktech DCT?
