That's a good question. I DID make sure the filler in the carto was saturated. And I DID leave about 1/4 inch of room in the tank when I filled it. When I take a drag or a dry hit, I see little bubbles occasionally emerge from the two holes in the carto. But every drag is dry and scratchy. Unpleasant.
Every so often I take a look at the top of the carto while it's still in the tank, and it's *always* dry. So I give it 4 or 5 more drops, so that it appears saturated again. I take a drag, and that FIRST one is decent. But each successive pull is dry and scratchy. Not burnt.
It's a dual coil XL smoktek carto, and I'm using it on an eVic. 2.2-2.3Ohm. I'm firing at 3.7-4.2V.
I just gave up and transferred the juice (happens to be Smokeless Image's RY4) into my VapeOnly Mega BCC.
Aaaaahhhhh....much better.
Anyway, back on topic. I do believe the Raven will work much better. I'm looking forward to having no filler
to deal with.
