I have a Murray 5.75 Quantum mower that I call Ol reliable. I have had my Murray for sometime, well the other day my rope broke so like an idiot I took it apart, put the rope back in and the durn thing did not want to retract, so after numerous tries I finally got it to retract now thin is before I put in back on , well once I got it back on I yanked on the rope and it locked on me, I could hear those little plastic swivel pieces not letting the rope retract. Does anybody have and suggestion on what I should do?
