Recently I had some trouble tuning my bow. Several responses to my post about tuning suggested I look for cam lean. Since this topic came up from several different sources I figure it is not just an individuals pet peeve, so now I am curious. Cam lean is not a term I heard back in the olden days. From the name I assume it means that the cam is not parallel with the string at full draw. Correct? Also, how does one tell if their bow has cam lean? What are the symptoms? And finally, what does one do about it when it is detected?

Thanks....
