So, i cleaned my unused, prefilled, ry4juice go-go carts. I filled them with new juice, and when i go to vape, i feel nothing and produce a tiny tiny amount of smoke. What could cause this? There is a little hissing/bubbling noise when i hold down my button. Ive tried twice now, in 2 different ways, to no avail. Sorry about the repost but the model specific forums are dead....
