So my "NEW" Osprey shoots OK but not nearly as hard as my old one, I knew it was set lighter whe my son pulled it back. I love the smoothness and seems to be set at very little letoff cuz there is maybe 3inches after the wall in the draw. So to turn it up I just loosen the red timing screws and crank down the main limb bolts? Also can I replace those rusted out main bolts with the ones off my Screamer? is it going to blow up in my face if I try to tke those screws all the way out?:cf:
