Thanks Yankee!! That was my thought when I saw the bubling, so I'gonna pinch the top and see what happens. As for harsh taste, not really, burning, not really, but my 901 does taste better!!
Pinch it. Don't CLOSE it. If it still floods, pinch some more. But take a few vapes in between because as you know, one vape post adjustment won't vape off what's there instantly.

Pretty interesting!!
