Small Engines (Lawn Mowers, etc.): Pull sting broke on my 49cc pocket bike motor., 49cc pocket bike, recoils

Question
i have a 49cc motor on my pocket bike. I tried to start it up using the pull start and the string pulled completely out. How should i go about repairing it and what parts would i need to buy. I would really appreciate an answer. thanks alot for you time.

Answer
I recommend for everyone that asks about repairing recoils to take it in to a good shop.  It can be more expensive and dangerous if you are unfamiliar with repairing them.  If you ask, they may let you watch the technician do the repair and you will see how to do it if it happens again.  Hope this helps.
