Welcome Steve!
Another consideration is to "fluff and thin" the tails of the wick. After I've cut my wicks to length, I will spread them out and maybe even pull the tiniest bits out so it's more of a "fan" than a "tail"
I SERIOUSLY struggled with my kayfuns and my first Kanger Subtank Mini until I started figuring that out.... I have been running the RBA on my Subtank for about 3 tankfuls, and I have yet to get a dry hit! (Yeah, I just jinxed myself

)
