OK, took the RTA apart, pulled out the wick, rinsed and dried it (ready to do the wick... properly) I have rinsed/dried three tanks over the last couple days. Rinse them in the kitchen sink (with strainer in case just in case, then dry them in the bathroom. I noticed a stray o-ring by the bathroom sink (clear about 1/4 inch) It does not go to my RTAs (they all have black o-rings that size) I don't recognize this clear o-ring (don't like mysteries) My best guess is it came off the drop-in coil on my little MTL tank. From now on, I will look closer at everything (even the old drop-in coils I am throwing away) Lesson learned.
BTW, I didn't post this thread just to rant and whine about how I messed up the re-wick job. I posted it because many other people are just starting out with RTAs and hoped it would help them understand that we have times where these things just give us issues (I have done this one at least 8 times and got it right almost every time... just old fool memory issues this time) Maybe (in some way) this can help newbies.
