Easy repair
The part fit and works perfectly. Here is a trick for getting the clutch off the shaft. Take the spark plug out and with the piston down, shove part of a small rope into the cylinder through the spark plug hole. This will allow you to keep the shaft from turning so you can break the clutch free, spin it off so you can get to the pinion.
