Sometimes my kaynfuns frustrate me so much! They work perfectly for months but every once in a while I just can't seem to put the right amount of cotton in and get burnt hits. I try less cotton, more cotton and they both give me a burnt taste. I don't know why this happens but it does and it drives me crazy! Then I usually just have to try 7-8 different re-wickings, then it's back to working like a charm for another coyote of months. Does this happen to anyone else? Just needed to vent.....
