It' s all apart right now. It was shooting like crap and I took it apart and the upper axel is bent. I don' t know if someone dry fored it when I wasn' t around or what happend to it. Any way it' s not going to be shooting like it is. If it isn' t cost effective to do that then I' ll just get a new axel for the idler wheel and have it checked out to make sure the limbs are still ok.
