Alright, experimented with the second Scorpion... Can never leave things alone.
It seems that the big difference between it wicking well, and not wicking worth a durn, is how long you let it sit originally.
You need to let it sit until the wicks absorb as much liquid as they are going to - and that takes hours. If you don't, the carto is likely ruined for life. That's a general conclusion based on one experiment, but I've read that this is, in fact, a common thing, and my experience supports that. First one: let it sit for four hours or more, the wicks stopped absorbing (the level of liquid in tank stopped going down - a bit more than a third of a tank absorbed). Second one: vaped it before the wicks were fully saturated, and even though I let it sit again after only about 15 puffs or so, it never worked right later.
And it seems that the time it takes for full saturation varies from carto to carto. The second one wasn't (the juice hasn't gone down enough) after 8 hours - and i've read of them sitting for full 12.
