Ok, decided to give this another go! All of you success stories are posing a challenge to me not to give up
I *think* that I have figured out the problem.
It's me. I've been putting too much liquid in the cart with the PTB filler (suprise suprise). Also...I've been trying to power vape on my Janty Stick, so I've changed my methods a bit in hopes that a) I won't flood my atomizer out, b) I'll be able to keep the PTB from prematurely drying out, in hopes that c) I'll eventually dry out the PTB, or at least, come closer than I have with other fillers.
So, a couple of adjustments. I took 1 PTB, rolled it tightly to start, then looser as I roll, fold directly in half, then place the filler in the 801 cart, with the "carpet rolls" on the buldging portions of the 801 cart, and the fold is somewhere down near the resevoir at the bottom (not sure if it's tucked down in there or not, I suspect it's not, but I cant tell). Obviously with a full PTB, it's sticking out of the top of my cart, so I pull it about 1mm out of the cart and trim it flush with the top of the cart with scissors, then press the PTB filler back down into cart.
I put 4 drops in to start, rotating one drop into each of the "carpet rolls". I then tilt the cart upside down to look for excess fluid. I do this over and over until I get to 16 drops, then put 2 more drops in to see if I get any leakage, and it seems at about 18 drops, it's starting to flow from the cart. So, it seems I can get about 16 drops in.
Now, another change that I've made is, instead of power hitting my Janty Stick, I'll press the switch, pull the vapors into my cheeks for 5 seconds, release the button, then inhale the vapor. If I want a bigger hit of vapor, I do this a second time.
My old method was just to redline until I get blinks (yeah, I know, I used to drive a WRX, what can I say, it's fun to push the limits!). Not only was I drying out the top of the atomizer prematurely, but I was likely also flooding the bottom of the atomizer as well.
I've been trying to give each thing at least a full day, if not more, before I give in, but this may just be it. Will post back tomorrow, but this may be the solution to the 801 dilema. Combination of filler type, PV draw method, and number of drops to fill the cart.
