OK, this wiring diagram is more representative of what you have. Your engine does not have those micro switches on the horizontal throttle gear. Yours has the cut out/ground switch on top of the block on the right side.
So, the two M wires from your key switch get connected to the engine as shown in this diagram:
One is connected to one set of points (there should be a black wire coming down from the mag plate that has a “knife connector”. The other “M” terminal lead is connected to the vacuum switch threaded post.
It is super important to remember that these two “M” terminals/leads on your key switch are not to be used for ground leads for any other accessories. If you inadvertently use one of these leads as a ground lead, you will quickly melt one or both of the coils.
By the way, your wiring job looks well thought out and very neat, nice work!
