Based on everything I've read here, I bought a foot of 2mm and 3mm. I don't know what I am doing wrong, but no matter what I do, I end up with a foul, throat burning vape. Smells and tastes worse than cotton getting burnt. I started with 2mm first and couldn't get it to taste good. Figured maybe it wasn't getting enough liquid, so went to 3mm. I've wrapped microcoils, spaced coils, wrapping with a mandrel or bit inserted, wrapping first and threading the wick in, it's all the same. And no matter what, the flavor of the liquid just isn't there either. I've squonked, even flooded the deck, plugging up the air hole and let the liquid soak the wick. I might get on short hit, then nasty again. Any help would be appreciated.
Sounds like the wick could be too tight. After I get the 2mm R/W threaded into my 1.5mm coil it will slide back and forth fairly easily. Not too loose and not tight enough to deform the coil. Then I put some eliquid directly on the coil and wick and burn it. I do this 2 or 3 times. Then I put the cap on and it's ready to squonk and vape. The preliminary juicing and burning eliminates having to let it soak. I got that tip from the RBA Supplies website.
Also if the wick fits too loosely that could cause a lack of flavor as well. I am tension wrapping my coils with the Wire Gizmo and leaving a little spacing between the coils as I wrap it. Hope that helps. I haven't experienced any of what you have described.
