Re: Help needed on 1971 6 HP
A broken rope (or one that comes out when pulled) damages the spring from backlash. No shortcuts, you have to take it apart and see what is wrong and fix it. That generally means a new spring. The new one must be pre-wound the correct number of turns or you will damage it too. I believe it is 16 turns, but verify that. And that rope should not be coming out if installed the way the picture shows, and you are using the correct rope. If you are using some kind of flimsy hardware store cord, you are on your own.
