You shouldn't need to open up the sprag clutch Figarow, just inspect and oil (1 drop) the end of the crankshaft where it extends into the starter. However if the recoil starter is showing any signs of slipping, or sticking in engagement, you will need to clean the clutch. Because it is a sealed one, it shouldn't need that unless the previous tenant sprayed the clutch with lubricant and thus messed it up.
Please come back and confirm when you have verified that it was the clutch, and there is no other problem.
And bigted, thanks for chipping in when I missed the clutch issue earlier in this thread.
