To add to the post by HarleyT : there are 2 white plastic jellybean shaped covers on the visible face of the flywheel once you remove the starter recoil assembly. each will have a slotted screw to loosen. The plastic clips on the underside of these covers are usually brittle from heat and age so be gentle. Remove one cover and rotate the open window over the points located around the 12 o'clock position.
