John Deere 140 No spark

Ive got an early i believe John Deere 140. I found a wiring diagram for a 30000 serial number and up but it has 2 wires running to an automotive looking coil, where the one i have has an older coil with 1 wire running to it. I would go get the serial number but its late and its out in the shop...

Ive got no power to the coil when i turn the key on, but when i crank the engine i do get power pulsing to that wire. Would that suggest a bad coil? or should the coil have more constant power.

That's the beakerless solid state ignition not the coil ignition
With solid state its a 69 I would trade you a coil ignition setup for your solid state if you go that way as previously suggested let me know if you go that route.
A rod goes in that hole to control the points. Above and below that hole are screw holes to mount the points. Above and below those holes there is 2 more holes where the points cover screws on.
The cover in the picture covers the cam gear not the points.

I couldn't find a mount for the points in arms reach but you get the idea.

The thing I dont knoe is if he should be changing the stator
Stator feeds to battery and straight to the coil on a solid state.
