"recoil starter"
The string broke? if that's all that broke, that can be repaired in 5 minutes. Go to lowes, they stock the pull cord. If you swing by the east broad Lowe's between 9-5 tomorrow i can even tell you what you'll need to do. if more than just the string broke, then you're in trouble and you'll have to order the parts from the engine manufacturer.
Magnetos are fairly easy to replace as well, just a bit more time consuming than the starter.
