I was looking down the string and arrow and noticed that the top of the idler wheel was leaning to the left. Not sure what to do with the season coming I put some string twist in the cable to straighten it out. Did I do the right thing? Is the limb failing? I never noticed it till now. The thing is...after doing this the bow shoots bullet holes through paper again, but looking at the cable at the " Y" where the twists come together, I can see that the one half is shorter, thereby possibly tighter. The bow is an MQ32 about 4 yrs old. It shoots great, but I' m just curious if I should have it looked at.
