I recently bought a Kanger Evod Pro just to give it a try and it seems the coil is flooding. Gurgling, popping, etc etc. I've checked everything and took it apart and made sure everything was tightened. This top coil design is new to me and I am not sure if the techniques I use to prime coils in my other tanks where the coils screws in to the bottom is the right way to do the same for this tank. Does anyone have this mod/tank (or similar design) that has some good pointers? It could possibly be bad luck with the pre-installed coil, maybe a bad coil. Thanks!
