See all pictures for the best description! The base of this magneto has cracks and in a few of the pictures I point to them with a screw driver. End plate has a chip. Mounting threads look good. This mag does turn over and produce a spark by giving it a quick spin by hand and scratching a test wire against my bench. I don’t believe it’s a strong enough spark to start or run a engine however. Please see pictures for the absolute best description.
