So here's my problem. I've been using my Fluid Flask since Nov. or Dec. of last year and it's been great. Using 3 ohm prepunched Boges between 7-8.5 watts with a 70/30 juice (not a dark one either). Of course I'll get some bad cartos here & there, toss it and move on. But the last few weeks I've been having a severe wicking issue. I use the Toothpick method that I've seen Baditude recommend and it's always worked flawlessly. I put the carto in snap the top on, making sure the air pocket is over one of the carto holes. The first 2 or 3 pulls are great. Then it dries out aaaannd....garbage. Now- on the Fluid Flask, the drip tip & top cap are one piece. When you snap the top on it creates the pressure and you vape away. I've noticed that I get no (or minimal) bubbles when just taking a dry pull. And if I gently lift up the top cap, it will pull liquid in and i can take 5 or 6 nice hits before I have to rinse and repeat. This leads me to believe I don't have a carto problem, but a pressure problem. Is this something that is caused by worn out o rings?
