Well I think I found the problem. I must of shimmed one of the gears to much, causing them to hardly turn at all. Gears reshimmed, now the gearbox cycles just like it should. However another problem has arose. the bbs barely come out at all. On semi auto no bbs come out, on full auto they kind of just poop out randomly. Iv seen this before when my tappet plate broke, but the tappet plate is fine... *face palm*
