Try organic cotton balls. Adding or removing fibers from the wick you can get a perfect fit every single time.They are really small 2.0 checked,am not sure coil size matters too much I've reviews were they used fused claptons from wotofo and they're bigger than mine,am using cotton bacon v 2.0,am sure it's a wicking issue of some sort,I've wicked it over 20 times since I've received it,am even ashamed to admit it lol.thanks again for all your help;-)
I do the same thing with Rayon.
Cotton you want the wicks tight but just loose enough to slide in the coil. When it is juiced the cotton will swell and fit the coils perfectly.
Rayon you have to have the Rayon so tight it squeaks.
Cotton swells when wicking
Rayon shrinks when wicking
