How do you fix my 47cc pocket bike pull starter?

If the cord broke its acutally not that hard to fix. Take off the cover over the pull starter. Because when you take it off that you don't drop it because in some cases the assembly will just be sitting in there and if you drop it you could have a big mess! Remove all old pieces of the rope. Spin the part the pull rope gets tied to around about 6-10 times. Once you spun it hold on to it and feed in the pull rope. Be sure to only put it in where it will pop though the hole. Pull it thought the hole. Tie a knot it about 2-4 times over each other. Slowly let go and it will wind up. If it doesn't wind up you either have to long of a rope or didn't wind it up enough.
