I think the flavor wick removal was what burned me here. Originally I had the wick in the coil and what seemed to be two flavor wicks on top. I removed both as per a suggestion I read from other Protank users. I then put this head aside and began tinkering with other stuff. When I got frustrated with my failed head builds I came back to this guy thinking it was the original untouched head. When the flooding started and I was out of ideas, I posted here. Anyway, lucky me I did not throw out the wicks I removed. I added one of the two wicks back and began
vaping. It's been an hour now and it's still going strong with no issues. Before it would begin to gurgle and spew droplets of liquid up the center tube into my mouth during a draw. Sometimes it did it a matter of 4-5 draws into my vape session. I haven't had this happen one time so far. I even let the Vamo/Protank sit on its side and fully cool off, start again, vape with it upside down, right side up, etc. I just can't duplicate the issue I ran into before... so clearly... re-adding 1 of the 2 flavor wicks was enough to bring back the seal I needed.
Oddly enough, in one of the videos I saw about removing the flavor wicks, the user specifically said he was only going to remove 1 of the 2 wicks. He never said why... he just simply said, I'm going to remove one. That's it. Looking back, I should have probably caught on, but eh... we're good now.
