This is a Yamaha 2-cycle magneto flywheel / magnet wheel (still very strong and in good condition) and included the backing plate, points set and coil (that I would use for extra parts as I have no way of testing - so it's a parts-only bargain) I needed a CDI based set-up so this won't work for me and am selling this for what I paid. These vintage parts are getting hard to find so if you have a points based magneto, ou may want to have a spare.I have seen complete new ones costing many hundreds of dollars, nd I am selling this for $65!
