That is almost funny. As you were probably typing your post, I was tossing my clone in the garbage, for the same reason. I had a good coil, just checked it before filling the
tank. But when I put the cap on, I was getting that burnt taste. Unscrewed the cap to check it, but ended up unscrewing the whole thing outta the base.
Drained the liquid and washed it up, but tried to unscrew the top of the coil and just couldn't get it loose.
Pulled out the wick for later, and dumped it. I bought two, so I still have one left, but its just too high maintenance.
