The white/brown wire is white/red. The white/light green goes on the terminal next to the heavy brown wires. The white/red goes on the terminal out on its own per the wiring diagram.

I presume it's from a 1979 B with a pre engaged starter in which case the pinion gear won't spin until the solenoid pulls it forward to engage the starter ring on the flywheel. It sounds like an inertia starter from your description and if the pinion doesn't spin forwards then the Bendix probably ne...

Is there a rev limiter on the electronic ignition system?

Why not get an electronic pump and do away with the points.!BFS in Salisbury sell them and they do tick and I can vouch for BFS as they rebuilt my HS6's and 4 Zenith Land Rover carburetors.
