You see, THIS is one of the reasons I crawl around in this forum. You just never know when you get an awesome answer to a problem. Just last night my juice, after exchanging a wick, started tasting off, just a slight dusty metallic taste. Changed juices, changed wick, same thing. After reading the above - eureka - remembered one wrap got twisted to half an overlap when I put in the wick. Put in a new coil - problem solved! Thanks for sharing, Jwat. Incredible, that such a small little thing can have such an influence.
