I don't know if this helps but this is an easy way to wick that i have found with Japanese cotton, First I take the drill and twist the cotton around it one and then cut it. Then i roll it with my fingers tight enough so that it can pass through the coil works evry timeNo on tc,that was my next question how dry are you running before refill ? I might be refilling it when it's too full therefor pressure is making it leak,I think next time am going to run it so the juice is bellow the chamber and see if that helps out,thanks a lot for all your posts and thoughts guys I really do appreciate it;-) please let me know how low you run your tanks I'll keep my fingers crossed;-)
