ok i am still a noob at all this just to let y'all know lol. so i rinsed my evods and kanger pro 2 with water to practice and i just keep getting gurling from each of them. it is getting frustrating. I let it air dry for a few hours, maybe at most 3 hours. i know for sure im not getting ejuice in the center hole because i fill it with a needle bottle. i even switched out the unused head that came with the protank 2 and its barely getting any vapor and still gurling. What is causing all this? Please help! Please bare with me if i don't reply back in time because i am really trying to see what the problem is. Thanks
