I bought a Genesis in the classifieds here a while back. I was letting a buddy try it out one night this past summer and it blew up on him (i.e. the string derailed). I checked it over good and was able to get it put back together with no issues. After I got it put back together, I noticed there was SIGNIFICANT cam lean on the bottom limb. It was like this before the 'blow-up', but I would like to fix it before I let any other guests use it. I tried a couple searches and came up with varying instructions on how to fix this problem. Anyone have any insight for me?
