It uses a yoke to encircle the pivot pin, but why? And we all recognize the 45SS gearcase; fast, bullet proof, and parts are readily available.
As for ignition, the second set of ignition primaries are indeed spliced. But can you explain how it fires 4 plugs per cylinder? The next question is what benefit might 4 plugs (firing simultaneously) do for the engine and why?
Sam is concerned that there are four carbs instead of two. The parts list clearly shows that each two barrel is only one carb, and FE/850 rules clearly state two of "any OMC make/model carburetor" for this powerhead. These just happen to be vertical instead of horizontal shaft. But why choose these?
There are a few other mysteries yet to be identified. Keep thinking and see where the images take you. Good luck!
