so I tried my hand at rebuilding. I did cheat a little with pre made coils that are .5 ohms as my hands cramp really bad and wasn't sure how much I could do going all in with making my own coils. This is on a Kanger mini rba. Anyway, itturned out looking ok but when I fired it, I get a loud popping sound no matter the wattage. I googled it and all I could find was maybe I didn't use enough cotton. Any suggestions or thoughts?
