Hi I'm Seth. I've been vaping for a couple of years but am still fairly new. I have a Joyetech Penguin that worked beautifully til I changed the coil. After that it was always burnt. So I figured I would get a small sewing needle and gently poke a couple holes in the juice entrance in the coil. It is working great every time now. Hope this helps anyone else that's having the same problem.
First off, Hiyas and welcome to the forums.
Second, it's not uncommon for that to be needed for any atomizer, and it's not their fault either. The companies need to make their atomizer's work for all juices..both the thick and the thin juices. It's a safer bet to cater it to thin juices, and have them poke holes in the cotton/wick for the thick juices. If it had a thick opening, then the thin juices would leak, and there's almost nothing that can be done to fix that. Just keep that in mind when you buy your juice... look at how thick it is now. If you find one that's more watery, then it might leak if you poke holes in the entrance.
