Adjusting the valves - looks like a cover plate at the bottom of the V will let you get right at them, with the manifolds removed, right? And few inches to work with.The single carb is 'pressure fed' somehow,and has some sort of linkage for the optional clutch control.I'd like to ask the man who owns one.
Here a good picture of one.Lots of priming cups to fill.

I've added a pdf of the factory manual. Different era for sure.
I've added a photo of the engne, the intake manifols may not need to be removed to adjust valves.
