Stephane I think you are learning all about a Cub. And I think you will be able to help your friend with his Cub.
Good luck with it.

The thickness of the oil pump gasket is critical in order to have oil pressure. It should be paper thin as shown on TM's site :

The one in your picture looks to be too thick.

I don't know if your metal protector acts as an electrical insulator or not. If it does, be sure you have good ground connections between the engine block and the magneto/ignition unit, the generator, the starter, the bell housing, etc.
 
Hi,
I would remove all paint from the metal where the engine touches the clutch housing, the front end bolts to the engine, and all large castings bolt together.
There should be no paint under the battery box, and on the right extension, around the battery box bolt holes, so there is bare metal for the battery box to ground, if you are connecting the ground cable the original way, to the side of the battery box.
Most of the metal under the battery box can be painted.
Another place to not paint is around the bolt holes under the dash, so it can ground to the clutch housing.

They need to be bare metal so the electrical system will ground.

Masking the parts when painting is one way to keep paint off. :)

Very nice, and reusable, too! Years ago, we had to make our own head gaskets for my brothers pulling tractor, it takes a lot of work and patience.
