Okay so I have a bit of an odd carto problem. One of the tanks I got with my AD kit does not want to vape on the OMG battery. I works on my DAV, and I have yet to try it on my VV because the battery is charging for work tomorrow, but its strange. I notice that the carto gets stuck on the 808 connector when I try to remove it so I have to hold onto the drip tip while unscrewing it or face the wrath of my RY4. Feels like the threading might be a bit off. Anybody else have this problem? It's the default DC carto you get with the OMGAD kit.
