is the juice on the thicker side? or is it fairly thin?
You have to remember that getting a tank to work correctly isnt just about making the hole the correct size.
Personally I dont think the size of the hole is even the most important part. You have to remember to periodically take dry pulls, which will feed more juice to the carto. This is especially important when using thicker juices, but should also be done with thinner juices. Take 3-5 short hard dry pulls and that will feed more juice in to help keep the carto wet. If your hole/holes are the right size, you should see air bubbles come out of the punched hole when you take dry pulls. Try doing that and that should help keep the carto wet and avoid getting a burnt taste
so these dry pulls, i dont fire it up when i do that do i?
also is it vg or pg i get to thin it out?
