So I have an ego4 with a tank I can take apart and one that I can't take apart. The one I can take apart I have and cleaned it, did a dry burn and can now see a nice clean coil. It still feels clogged when I hit it. I blew out on the piece in the middle. The other tank is new but it seems to burn if I don't drag as hard as I can. What's going on with these?
