The Nautilus will gurgle on occasion. The way to solve this issue is to turn the entire unit upside down
and take a medium smooth hit/draw. What this does is vaporize the extra juice in the coil, and at
the same time, being upside down keeps the coil from rewicking the juice because the juice level is
below the wick holes in the coil. You may get some small amounts of juice into your mouth but just spit
it on a paper towel and you'll be fine. After this one draw, turn the unit right side up and you'll
probably see a few small bubbles come from the wick holes, as the wick resupplies the juice naturally.
The flooding of the coils is usually caused by too hard of draws.
Congrats on your vape journey and welcome to the forum.
