Okay, so ive got a problem that i dont understand at all.
My dna plays really well with stacks and the stacks are smooth. They make hardly any noise and are real nice. When i move those exact same stacks to my Grind Machine 2 and perform a pull start with them, i feel a real hard vibe and it slows the yoyo spin time down drastically. I wonder why that is? The stacks dont slow the gm2 down unless i hold them, to specify.
perhaps the stack post, which is the only thing that i can think of right now, is damaged?
