Riddle me this, MT gurus...Still trying to NOT put this tank in the "nice idea but not working out" bin. I was having wicking troubles that were mostly related to not having the coil centered I believe. Now the coil is centered and I wick it like the pics on page 41. It doesn't leak or seep. Fills fine. The first tankful is bliss....Awesome flavor, performance, and wicking. Bubbles on every draw and random bubbles when sitting. Soon after the 1st refill it is a complete vacuum lock situation. I cannot get any wicking whatsoever. No bubbles even when mostly closing the airflow and drawing hard. The only way I can get any wicking is to open the top cap which will cause a few bubbles and I can take a couple of hits. I even let it set overnight last night with the tank full and to cap completely off and AFC open. No leaks this morning. I have tried more cotton, less cotton, same thing.
Any ideas...About ready for it to hit its grave!
My guess is overfilling. I've had that happen if I don't leave a big enough air space. Not on this tank, but others.
If the first tankful ran perfect, it is the only variable that is different.
Yeah, coils can gunk, but then your juice just tastes off.

Wooot! Got to work an hour ago and had nice vape mailz! 60' each of 28g and 26g SS, another Bellus, and two suite drip tips!
