Thanks for the link BigEd. If not engaging should the G83 spin 360 degrees?
With the kickstart in the up position the G83 rests against the G116 which a flat strip spring that acts a shockabsorber when the return spring G87/1 returns the G83 to the up position after kicking.
when kick starting the G83 engages with the G46 to turn the engine. When the G83 moves fully past and out of engagement with G46 it hits G97 which is spring loaded by spring G92 that acts as a shock absorber. Sometimes the section of the casting can break around this shock absorber if it is not functioning correctly.
G46 gear is held in engagement with G97 by spring G48. As G83 moves back up the ratchet formed by G46/G97 comes out of engagement.
The angle that the G83 can move through is approximately twice the angle of the G83 which is the angle between the stops at each end of the swing. I've not measured the angle but it is probably a little over 90º.
