So, I finally thought I had figured it out a couple of days ago and it was wonderful. The tank was feeding the carto just right and the vape was great. I even added juice to the tank once and it was still good. But, then I did it a second time and it seemed to stop feeding the carto the juice it needed. I tried taking huge tokes without pushing the button, putting it back in the IBTANKED thingy and nothing seemed to work. Before long, I tasted a burnt taste. So, I swapped out cartomizers and tried again. I still isn't feeding. At this point I'm wondering if I somehow setup some kind of reverse vacuum in the tank or something. If I have, is there a way to reverse that? I'm somewhat frustrated right now.
