Exactly what is broken? If just the shift handle, you do not have to pull the powerhead. But if the shift shaft that goes through the exhaust housing, then you do have to remove the powerhead. Take a deep breath–it isn’t as difficult as you might think.
To make reassembly easier, remove the shifter interlock bar from one side of the powerhead, and remove the vertical throttle shaft from the other side. Disconnect the hoses.
There are several screws around the rear, below the pan. There are two hex nuts near the rubber mounts on the sides. There is another hex nut inside, below the carburetor. If I haven’t forgotten anything, the powerhead should now lift off.
No, you don’t have to remove the flywheel or carburetor.
