New string installed today. My cam looks to be under rotated.(opposate direction the cam rotates when bow is drawn).How will this affect perfomance.Will it reduce let-off or draw weight, slow arrow speed down? Thanks, pahunter

I would think that you should have that fixed. I'm no expert, but the advantage of having a single cam is that it should be easy to get it tuned in properly. Also they don't require the hassle of timing two cams. I would think that would slow your arrow down by not using its potential energy efficiently. Also I think your let off will not be as much. It will not roll all the way over to the point of maximum let off. Just a few thoughts.

What type of bow is it?
