Figured I should bump this instead of creating another new thread for the same issue.
I'm getting the same problem as the OP with my v3. The collection tank itself will have very little
juice in it (I can see the bottom) but I'll always get a large amount of juice along the rim of the CT where the air intake holes are. Wiping this out temporarily alleviates the issue but the juice will eventually collect again.
So far I've been mitigating this by
vaping with the holes pointed up, since trying with them pointed down invariably leads to the collected juice flooding out of the holes. It also requires that the control ring be opened all the way to avoid flooding the atty. The juice tank doesn't visibly leak (unless it's an extremely slow leak) on it's own and i only notice the collection around the air holes after
vaping.
The only thing I haven't tried yet is tightening the atomizer all the way down to the 510 connector. The collar that covers the air intake holes on the atomizer has sections cut away for the holes, but when screwed down all the way they don't align with the intake holes and block about 75% of the holes. I suspect that would seriously affect the juice feeding to the atty, so I don't quite screw it down all the way.
Is this just an issue with the atty? Would unscrewing the center pin fix this?
