I have a Z-Atty Pro and I built my own coil and was very very happy with it. I attached it to my Natural mod and I think I over tightened it and the black delrin shaft moves up and down now? I put it on my pro Vari and it read OP so I took the cap off and pushed it down and it worked. So basically the pin on the bottom moves up and down and So does the centre shaft? They move easily!! did I break it and is it fixable???? Here are picks of what I mean. Help please??
