Re: part name and function

The part you are describing is the neutral interlock. When the engine is in gear and timing advanced, the switch rides off the bent metal cam and the starter can not be energised. This old system was later changed to have the switch below the carb and a cam on the shift lever. The reason is: Since with the ols system the engine can be shifted into gear without speeding up, it is still possible to start in gear. Since the new switch design has the cam on the shift lever, If the engine is not in neutral, it is not possible to start it---much safer.
