I just got a kayfun 3.1 lite clone and have been looking forward to building on it. But I guess I got a less than stellar clone. First the post screws wouldn't tighten down on coils, as they were too long. (I fixed this with a little careful sanding down the length.) Now I can get a coil installed, but it won't read on my Ohm reader. I even pulled a coil from a dripper with known qualities (2.0 Ohm, works, etc) Anyone got any clue what could be wrong? It will fire, but I don't really feel safe not know why I can't get a read.
