Today was my first time punching a cartomizer and filling a tank. I did a damn good job filling the tank, but I'm not seeing any bubbles coming out the carto holes as a take a toot. I used the saddle valve method, though I had some trouble because the poker coming out of my vavle is a little crooked. I know your supposed to do something like a full 180 degree turn after the puncture, but I may have not gone deep enough. The holes certainly look pretty significant in size, but i'm concerned the juice isn't feeding though. Any thoughts on this?
