Shop accidentally sold me a Ni200 coil 0.2 for my arctic tank instead of BTDC 0.2 coil. I have X Cube 2. I have never used TC before. I indicated NEW coil, I set it on TC, nickel coil, 0.006, double coil, and I think I like around 500+ F. Not sure if I set this up right, but I know coil is screwed in tight. Juice is leaking into air vent part. Can anyone troubleshoot why?
