Hey brian, I'm also using a Fogger (it's the regular V4, but I'm expecting a black V4.3 too). Loving it but it can't keep up with my Ruthless E-juice which is 85-90% VG. I usually can take a 2s pull, not longer. Then I have to tighten down the airholes, take 1-2 primers so I can take another one. This is @ .8Ohms on a mech.
As mentioned before, I'm currently looking to purchase this which should function like the bottle stuffing.
You think that will be enough to fix this problem, or should i look into importing some Cellucotton or something else mentioned here?
Also might be wrong thread, but what gauge wire did you use for your .4Ohm build?
Thank you for the tip about tightening down the air hole in the Fogger and taking primer puffs. That was a huge help when the vacuum is too tight.
You might have too much wick in your wells. With thicker juices, I usually only use a pull a few strands in to the well and blot the majority of it right about the well opening. You might have to wet the wick to do this, but as long as you don't have a gap above the well it should not leak. If you have cheap juice, try it with that first.
