So I got my kayfun a week or so ago and love it. I just built a dual coil, or the double barrel that Rip Trippers shows you how to build and its working great. So, I was screwing with the adjustable airflow screw, literally, and I wasn't paying attention, and the screw kept going down and now it looks like its under the threads and I cant get it to come back up... it spins and feels like it tightens a little but it wont come out. any ideas?
