Burnt taste usually comes from running the atomizer too dry.
But at the same time you seem to be dripping too much because of all the leaking.
This is a contradiction, and my only explanation is that your atomizer really sucks.
It seems it doesn't hold very many drops, or maybe it is just a leaky atomizer.
Actually, that could explain it, your atomizer leaks.
My standard Joyetech 510 atomizers hold 5-6 drops after blowing all the juice out...
And then they get 3-4 more drops every time they need a refill thereafter...
I don't think you can get a burnt taste with bridgeless because there is nothing to burn. I debridged one myself and there was wicking material in it.
The silica wicks don't burn.
