That happened to me as well on my first carto that was 5 days in. One second, it had the perfect draw. Then on the next drag, nothing. It had no draw at all. I took it off and saw the air hole was completely blocked, like the whole insides collapsed. I also tried the paper clip with some success, but not enough to make it usable.
The burning does concern me. I have not torn the original carto apart to look, but I wouldn't be too terribly surprised to find mine burnt as well. That leads me to some questions that might have been answered here, and I have read all 190 pages of this thread. But I'm suffering from information overload. Here goes:
The liquid never wicks to the top of the carto, and it always looks completely white and dry. The consensus seems to be that is normal and a non-issue. But I really think it's contributing to my biggest (and, so far, only) complaint: severe reduction in taste. I'm not really tasting the filler, and I'm not getting a burnt taste. But I'm not really tasting my liquid either. I switched to a more flavorful liquid, and that helped a bit. But the taste is still drastically muted. So I'm not enjoying the vaping experience as much as I should.
If I could solve that problem, this thing would be my ultimate accessory. I love the way it's built and how easy it is to use. I just need to solve this wicking issue, which I think might be contributing the the filler burning. And that's because I find I have to sit on the button longer to heat up the liquid enough from the bottom of the carto in order to get a decent TH and modicum of flavor.
I had wondered if this would be a problem, and if a "horizontal, bottom coil" carto might work best. For most cartos, the coil (or coils) are oriented vertically going up the center of the carto positioned about midway. Some cartos, however, use a different design - a horizontal coil at the bottom (think atty with filler on top):
- 808: Bloog max fusion, Volt, and NHaler "MF style" cartos are bottom coil
- 510: SLB Gold cartos are bottom coils
I have read that the SLBs have problems because the filler is very spongy and soaks up juice so much that the filler swells and blocks the airway. I don't know because I never tried them.
I ordered a stealth 510-808 adapter and MF style punched carto from NHaler but havent tried it yet. The stealth adapter looks awesome and adds only a millimeter or 2 of length (if that)
Vapor-Age also sells a punched SLB carto.
Theoretically (in my mind) these should be difficult if not impossible to burn!
