Well first off , welcome to Vu
And on to your issues , could yo post some pics of your wicking , and coils . On the griffin they always say less is more and all the good comments but I will try to explain what works for me .
I almost always use a 3mm I'd coil though 2.5 will do nicely as well here , go with 6 wraps and have them as high as you can go on the posts . Next pull your wick through , not.too tight though because it can choke off at the coil , I have the same issue sometimes , next tuck your wick to the juice wells and make sure your ring is on and there is a little wick protruding below the ring . After you have it tucked in , juice it up and gently pick up the wicks from the hole and set them back down , do this once or twice to get the ends kinda fluffed up . After this , with the wicks sitting down , get a needle or a paperclip and on the outside edge away from coil posts , insert the needle or paperclip into the juice well to open a small hole for venting . One this is all done , carefully put tank back together and you shouldn't have any issues . If you do try to loosen the top fill with juice flow control open and see if you get a bubble leaving the chimney , if so the vent hole needs to be opened a little more , repeat the lift and set. Method and open your vent hole a little bigger .
Hopefully this will help , there is a video here in one of the threads on wicking of this tank I believe @ray2mou has one of the better ones if you can search him . Once I get off work and around a computer I can search and post if you cannot.locat it.
