Its a known issue. That burnt tire taste is why I call the failomizers
And when my Dualie starts tasting like a dirty sock (and they do, at least once a day if I'm not constanty topping them with juice), I pretty much have to throw it away after a day or so of use. So I guess these are a fail too.
At least with a Failomizer you can give it a shake, wash, or burn...and use it for another week
OK, if you're getting dry hits on a CE2 here's a few things that can help.
1. Shake it up a little...particularly if it sat a while unused. See...oxidation can form on the surface of the liquid that touches air and slow down or even stop good wicking. Shaking it up can help break some of that film.
2. Warm the whole carto...in your hands...with a few burns, etc. E-liquid flows better when it's warm.
3. If you like long slow draws...consider getting higher resistance ones next time. I like the low resistance ones, but I take quick hot hits...hence never get the dry hits.
4. Pull the bottom most silicon plug up so there's a little more room around the wicks to let thicker juices by. Some folks even pull it out and flip it upside down (the upside down does leave two gaps over the wicks that can leak), or just leave it out all together...only using the middle washer-like ring.
5. Several mods can be done...a little more involved but none are terrible difficult...and you only have to do it 'once' and you're set for many hours of trouble free vaping.
a. In the bottom silicon ring, Cut the grooves a little bigger that surround the wicks.
b. Pull the silicon rings out all together...optionally replace with a bit of filler of your choice...PTB, or a bit of fluvol from one of your old carts/cartos works well. Keep the middle ring when you need the CE2 to be leak free and portable.
c. Cut the black shrink wrap jacket so that it stops right at the bottom of the bowl. That gives the wicks a little more room.
d. Tuck some long strips of pyramid tea bag material between the wicks and the outer sleeve. Some folks even snip the origional wicks much shorter with this mod.
Good news in the latest Revisions of the CE2...
1. They come with more 'optional' bits if you'd like to pull out the silicon rings totally and replace them with a bit of filler material instead (lets in more air and stops leaking if turned on side or upside down).
2. The black shrinkwrap around the bowl doesn't go as high up the bowl...so the wicks are less likely to get pinched off between that and the outer sleeve. Yep...lots of people were trimming that away with a box cutter as a mod before...
3. The wicks are longer...they reach all the way to the bottom of the carto.
4. They come with metal needles now instead of those flimsy nylon things...and word has it that in the future they'll ship with a kind of pipette instead.
