Just got a antique copper plated brass chi you clone from fasttech. None of my batteries fire this thing. Bottom cap ant top cap contacts are making connection to the battery for sure. The only thing i can think of is the 510 contact is too deep and won't make contact with my clearos. The pin can not be adjusted. Are there any solutions short of replacing ( you all know of fasttech shipping times ! ). I kinda like the look of the mod and would rather get it to work than return it.
