Starter will not engage engine

[theape]

On my last riding trip the starter motor stopped turning the engine. When starting all you hear is the starter motor turning. I took the stater off to see if any thing was wrong with it but every thing was fine. The only way I can start my quad is to push start it. I was looking to buy a pull start for a temp fix. This winter I will have time to take the engine apart and fix the real problem. Does any one know ware I can buy a pull start and why is the starter not turning the engine?

The one way clutch (sprag) on the drive hub where the flywheel is went out.. .I'd be careful here as there are many parts in there that can fly appart and you will send all through out the engine and can cause major damage. http://yfm350.proboards31.com/index.cgi?board=tutorials&action=display&thread=1176069957
