Ok, so I got setup with a 3.5 mL tank from smoktek and absolutely love it. I also tried some new juices that I really like (Gorilla juice and Boba's). I ordered a couple of extra carts for my tank, but when I went to swap out the carto for the new juice, it wasn't feeding and I was getting a dry burn. I let it sit for about 10 minutes and even put a few drops into the top of the carto to see if that'd help and still the nasty polyfil taste. Any ideas?
