Hello guys. I have recently noticed some differences between my first KFM clone (Infinite) and the last one I got (Ivogo). Aside from trivial stuff like the transparent tank being a bit wider and the chimney harder to screw on, I'm having a real issue getting it to wick properly without having to constantly prime the wick to get air to exit the juice channels. It's like the air bubbles refuse to form inside the tank, and a big one just forms inside the chimney.
In contrast, my Infinite brand clone works and wicks perfectly, with air bubbles constantly forming and floating to the top. I'm thinking that perhaps one of the juice channels or air holes is a fraction off in the Ivogo. I guess I'll just buy another Infinite clone and use the Ivogo strictly in dripper mode.
Check the juice channels going up to the deck. Sometimes they are cut so shallow, that there's barely any clearance for juice to go up them, or air to come back down. Take a microfile to them, right at deck level and deepen those grooves.
