I found with evods & the protank 2 mini that when i washed them & had the chimney removed from the atty head, & having rinsed the atty head too, i could then dry burn the coil with wick in place but only gently, just pulsing on the button & then stop at the first sign of red hotness. If i carried on it burnt the silica & then it was into the realm of burnt flavour.... Which was nice ! Other than that i dunno really.
How did you remove the chimney on the mini protank 2? I couldnt so i gave up at that point. Pair of pliers?
