Okay, just took apart a 2 day old carto that was giving me the harsh chemically exhale.
Came apart a lot easier than the other ones I took apart. 4 taps with the hammer and out it came.
The wicking material was a little brown near where it touched the coils but nothing bad.
The coil was quite a bit gunked on one side. That side was very close to the side of the center tube. So I dry burned and moved it until it was equally as distant as the other side. I had to dry burn to see all parts of the coil actually. Now the wick is a bit longer on one side than the other.
Then I dripped on the wicks and vaped through the center tube to make sure the taste was not altered and it wasn't so I wrapped the inner wicking material as tight as I could at the bottom of the center tube around the wicks of the coile. It flared out a little bit at the wicks but I did the best I could. Then I wrapped the outter wick material and slid the housing back on the base.
Then just taped the top of the carto with the hammer till it was sealed back up.
Vapes great, tons of vapor, just like its supposed to be. Hopefully my wrapping skill will prove good enough in the long run.
Also, even though I just topped it off by dripping till drops came out the bottom, and when I pulled out the stuffing there were lots of dry spots in it. I doused it with juice before I put it all back together...might be the way I do my intital fill from now on, because I had originally syringe filled that carto.
Anyway, that's my experience.
