Canadian Valiant with Direct Drive Starter

So here is the state I am in. There are three raised spiral tracks (for lack of a better term).
The spring loaded pin can ride on any of the three tracks.
Track one terminates in a hole. If the pin follows this raised track (retracts) it ultimately will fall into the hole.
Track two has a raised shoulder. After a ΒΌ turn or so the pin sits against this shoulder and won't travel (retract) any farther.
Track three will allow full range of travel with a shoulder (as indicated) that allows the bendix to remain retracted.
So how do I orient the pin? I can't find any diagrams anywhere showing how to re-assemble this bendix.
