I'm new to rebuilding. I have a nimbus clone, came with a coil around silica, tasted like crap. Rebuilt it with cotton and was pretty good. That was a week ago so I'm rebuilding now and every time I try it tastes bad. Usually tastes like dirty socks and now it just tastes plain bad. did 5, 6, and 7 wraps around the alan key that came with the atty, duel coil at .6 - .8 ohms. The cotton has been boiled. The coils were torched before place on the atty and wicked. I've tried making the cotton looser in the coil. They don't heat up perfectly even but close enough. I've had similar luck with silica. They legs are clipped flush with the posts. I tried a dragon coil. didn't affect the taste. idk what to do.
