I broke a pull cord a few weeks ago. changing it out I noticed where the cord goes throught the body work the insert had a notch in the bottom and the cord was fraying on it. I hung a small pully in front of the hole and thought I had it. Just broke again. The lower insert in the recoil also had a notch. I managed to rotate it to a smooth spot and it is better but what's the fix for this. The inserts are not listed on parts diagrams. Any help would be great.
