Sorry folks, I was in a hurry to leave work. Yes it is a kfl clone, the one with the air hole on the side. I have two others with the air hole on the bottom and haven't had any problems. Using 28g, 8 wraps micro coils. I have tried cotton over a two dozen times, very little, I can slide the cotton back and forth. Tried some other stuff that came with it, silica perhaps? Same deal, I have two of them and both do the same thing.
At first I thought maybe the coil was to close to the bottom so I built a bunch more and tried that, no change. Moved down a little, no help, same thing.
I'm going to take them completely apart and give them a good cleaning, since they have been recoiled and juiced so many times in the last week.
I also have a Aqua and a Fogger 4+ that wick with no problem. Going to try one more time before just buy something else.
