Be very gentle when tightening the screw in the side of the cylinder head that holds the decompression assy in place. The threads can be easily stripped.

You will need to re-thread the hole using a Heli-Coil.  The original bolt or a replacement must be used, as it has a pin on the nose of the bolt that retains the shaft.
