More than likely the clutch is damaged. Check the spring.
Clutch Bell on the front of the engine, not the slipper.

The clutch bell should not turn at all when you pull the pull start so it is not your slipper. Something is going wrong with your clutch bell shoes/springs or possibly your clutch bell bearing.

These engines use centrifugal clutches. Same as on go karts and mini bikes. Under the clutch bell(little gear attached to the engine that meshes with the big gear that's attached to the tranny), there's 2 shoes with a spring wrapped around them. The shoes and/or the spring is the problem. Give the inside of the bell a few swipes with some fine grit sand paper to remove glazing before reassembling. Same for the shoes if you reuse them. Use blue locktite(removable) on any metal to metal screws/nuts as well when you reassemble.

You'll be able to see the problem right away once the bell is slid off. Be careful not to lose the e clip!!!
Pay attention to where the shims are as well. You want just a "tick" of play in the bell. Any slop or grit in the bearings means that they need replaced too.
