GreekDude, yeah i'm gonna experiment around with the air flow thing...i actually thought i may have to start ordering a higher PG level because i'm more into the throat hit rather than the volume of vapor.
edit: actually just moved it to the second largest air hole and my ejuice can be tasted a lot better!!![]()
For thicker high viscosity juices you need the air holes closed down a bit to keep the juice feed up. For thinner juices, open them up. Vacuum is what feeds the juice to the wick. If it starts gurgling, open up the air. If you have to do primer puffs every time before hitting the fire button, close down the air a bit.
