Very hard to find original American Bosch FB2 two-cylinder rotary magneto. It is as found from an old collector’s estate and in usable condition for its age. It mounts on a 1 11/16 x 2 3/16 hole pattern and the threads are in great shape. It also has a larger mounting platform that one side has been removed by a previous owner. It is clockwise rotation and turns smoothly with no noticeable wear in the bearings. It has good magnetic pull and put out a nice, hot spark on both original leadouts that is sure to run an engine if set up properly. Everything inside the points cover looks to be in nice shape. It has a pinned coupler and the impulse seems to work as it should. These magnetos are pretty tough to find so if you need one don’t miss out on this one. The pictures tell the story. It would also make a great spare on the shelf.
