When I wicked one of my coils I kind of Mess it up (first coil I built) and now only one fires right, how do I fort the other one to burn, do I have to take the cotton out?
Start by checking and maybe tightening the screws, chances are one has come loose....you can vape on a single coil, depending on what it comes in at in ohms....if you choose to go that route, simply snip the other coil and you'll be fine....or re-wick....
