Hi as I mentioned my M91 has not arrived yet so I don't know if it comes with any running instructions.
I am now a little unsure of how the engine is lubricated. I assume there is no sump with oil to splash about the insides. Is it intended that you just use an oil can here and there from the outside or are there holes to get oil into the piston bore ?. Obviously vale gear is external.
