OK, after hours of messing with this, some colorful language, lots of juice, and a few days of numb tongue, I think I have it figured out. Some back story:
I bought my Nautilus tank because of the great reviews, and the larger tank. Used it for almost a month with the included coils, and LOVED it. Replaced the BDC coils that came with it with a new BVC coil. The thing spit like a cobra. Flooded, gurgled, and I was drinking juice all day. I took it apart and cleaned it. I blew it out from the bottom. I stood it upside down to drain. I checked the authentication codes on the tank and the coils (checked out). I replaced the coil (maybe got a bad one). I opened my air hole up to the widest. I used lower PG juice. Tried different voltage settings. I looked at every thread on the internet for advice. I called Aspire USA (they tried to help). I emailed Aspire, and they were no help either. So, I embarked on a systematic approach to rule out different variables that could be causing the problem. I won't bore you with the details, but here are my conclusions:
The problem is actually the BVC coils themselves. Not because they're bad, they're awesome when they work right. But because we're not used to using a vertical coil. We need to retrain ourselves to vape with these things. So, here's what I found to work
Rinse and wipe out the entire tank. Use a Q tip from the bottom and the top to get out any juice and/or water
unscrew your coil. Use a papertowel or Q tip to wipe this out.
screw your coil back in nice and tight
fill your tank.
drip 2 or three drops of juice on your coil
close your tank (make sure it's nice and tight)
use your collar to stand your coil up on the counter, and leave it set for a couple of minutes.
Attach tank to your battery or mod
take two light and slow dry hits (don't fire your mod)
set your air hole to the second smallest setting
fire your mod, then pull.
These like higher voltage/wattage settings. Part of the problem is juice that's not getting hot enough when it goes through the coil, so it winds up in your mouth. Hotter coil equals more juice vaporized and faster.
*notes The BVC coils need to be pulled on more gently and slower than horizontal coils, at least until the coil is nice and hot. This tank is designed to allow the juice to enter the coil very easily (that's why we get more vapor), so pulling harder just pulls more juice, which can't vaporize fast enough, which winds up in our mouths. See the problem? So train yourself to pull more gently (this isn't an analog) and slower. You'll get a great full flavor vape with lots of cloud.
If you happen to flood it again by pulling too hard, open it up, wipe it out (blowing it out doesn't really work) make sure you take out your coil and wipe under it. And don't forget to take off your drip tip and wipe under it too.
Iaying this tank on its side for a longer time (say more than half hour) seems to allow juice to seep in under the coil too. Just take it apart and wipe it out before you vape. Better yet, don't lay it on it's side to store it. Use the collar as a base and stand it up. Also, if you leave it overnight standing upright, drip a couple of drops of juice on the coil before you use it again. A dry(er) coil seems to promote flooding as well.
