I guess it is possible I'm missing something, but I only see two places for adjustment on/near the distributor. I see the bolt which is the octane selector, and I see the screw that clamps the distributor shaft. This is a stock 235, and the shop manual refers to loosening the "distributor clamp", so I'm pretty sure this un-accessible screw is what I need to get at. Anyone else have any ideas on getting a good angle on this screw?
