yeah I started realizing I spoke too soon... started noticing it not wicking again, loosening the tank would help for a while then it would gradually stop wicking again.
Changed coil yesterday (and this was a new coil I'd put in Sunday night - so it was only 3 days old) - drastic improvement in wicking... today after I left the house, no wicking again. tinkered with it, seemed to find just the right spot between tightening/loosening the tank and got it wicking again. Topped off the tank this evening, now it's not wicking again. I think I've figured out that everything has to be lined up exactly right for this thing to wick, otherwise it won't wick at all. I don't know exactly what type of defect could cause this bizarre behavior, but life is too short for this - I have become obsessed with watching for bubbles, turning the tank, watching for bubbles, opening/closing the tank, watching for bubbles... it's insane.
