Just rebuilt 3 kayfuns 1.3 ohms for use on my dna30. Two of them vaping great at 15 watts. One of them I have rebuilt 4 times now and still can't get to wick well enough to run at 15 watts..... really wierd. These 3 have been in use for about 6 months now and built the same way. No leaking from the trouble maker kayfun. Tip upside down then back up and bubbles come to the top. It will not wick on its own. Bottom filled all three
same juice in it that you always used? I know some of my strawberry juices just don't work to well at higher wattages. all my other juices work fantastic even up to 20 watts but a couple just don't.
