I would recommend getting the factory specs for string and cable length and measuring the ones on your bow. A string/cable that's close to specs, but not quite right, can be twisted/untwisted to get the correct length. Once the string and cable are the correct length, your cam SHOULD be in the proper position. The longer flat side of the cam should be almost parallel to the string on most bows.

If either one is stretched too far out of whack, it will need to be replaced as it is not recommended to put too much twist in them.
