With my leaks it just confuses me on how it happens because sometimes ill be able to go through more than half the tank, then it'll start gurgling and leaking. I'm sure I've wasted a lot of juice cuz of this. Sometimes ill set my kayfun standing straight up then 30 minutes later, I pick it up and have juice on my hand. Again, a slow leak coming from the air hole and always baffles me when it was working perfectly allllllllll day. I have noticed that when my cotton gets wet and puffs up, ill start to leak. I make a new cotton wick with a lot less cotton. Again, perfect for a good amount of time, then it leaks.
I've also done the "super 8" and made sure the wick was barely touching the channel and that it wasn't blocking it, vapes great for a bit and then leaks again.
I do make sure that everything is tight and that the o ring on the chimney is sitting properly on the top cap. I also make sure that the coil isn't touching the middle air hole inside.
Seriously out of ideas.
