For those of you having flooding / gurgling issues with the Nautlius Mini (BVC), I found a solution that worked well for me. When I first started using the nautilus Mini I had similar issues, but since doing a few simple things I haven't had a single problem.
1 - Screw the BVC coil directly into the top cap's center post - NOT the threaded bottom cap with air flow adjuster.
2 - Fill the tank well beyond the 2mm line, almost to the top of the tank, but leave about 1mm of space - you don't want it to overflow when you screw the bottom on.
3 - Screw the bottom cap onto the tank, take a couple of hard dry pulls (without pushing the button) and let it sit vertically for 30 minutes.
4 - Do not use the smallest air hole to start out with. I use the second-smallest air hole for the first hour or so. Use a bigger hole if you want to.
5 - Start out at a lower voltage than you will vape at once the coil is broken in. I start out at about 3.8V and work my way up to 4.6V (my desired setting) over the course of a day.
NOTE - Sometimes the first few draws will have a bit of a gurgle, but it will go away after 5-10 pulls.
If you're still having issues after this, I would assume your juice is too thin. I use 100% VG that is thinned (from Virgin Vapors) and it wicks flawlessly without flooding. Virgin's 100% VG juice is substantially thinner than traditional VG juices, but still quite a bit thicker than high PG juices.
Once I started filling tanks using the above steps, I haven't had a single issue. Hope this helps.
