Springs are missing and the little rollers are stuck. This magneto will produce a weak spark by giving the armature a quick spin by hand and scratching the lead out wire against my steel bench. I don’t believe it’s enough spark to start or run an engine and it is not a consistent spark. 2″ x 2″ mounting. Armature has side to side wear and I imagine new bushings in the plates will be needed. I believe this is a good candidate for a rebuild. Mounting holes are solid. I do not see any cracks in the pot metal base. The back bearing plate has a chunk/piece missing next to the little Oiler hole which most likely is from the trip mechanism hitting it. See pictures for the absolute best description!
