Can you tell me more? I replaced the cover with all of the starter mechanism, and it winds up and releases the crankshaft as it should. Besides that, there are no electrical components in the starter/transmission assembly. Is it a matter of installing at a particular phase in the 2-stroke cycle?

In the schematic shown in the shop manual, the yellow wire is attached to the lighting circuit (which doesn't care whether it's AC and DC current powering the head and tail lights), and the white wire goes to the rectifier, which I expect charges the battery by blocking the negative-going portion of the AC waveform.
