Here is a Acme JR. Friction magneto made by the Tritt Electric Co. It is in great shape. I hooked it up to a 12 volt battery and it spun just as it should. Please check out the pictures and see if you need it. For questions 419 789 1159. SPECIAL NOTE: This is friction type generator. This mag is meant to be used with a coil. It is not meant to be able to start an engine but is meant to take the place of the batteries once the engine is running. It in itself will not produce a spark that will jump an air gap. 4-3/4 on center mounting. Only very minimal wear. See pics for dimensions. Weighs about 11.5 lbs before any box or packing materials. I think I list items very accurately but my opinion on condition may differ from yours. In my opinion this is a great magneto. If you have any questions about how to use it on your engine please ask. Don’t be a clown and tear it all apart and then try to return it when you can’t get it to work. Thanks for looking at this listing!
