I found this in someone's trash. I got it running. Just took some sandpaper to the flywheel magnets, coil, and points. Started right up 2nd pull after that. I also took the rust off the handle with my die grinder, cleaned the air filter, changed the oil, and sharpened the blade. I am guessing by the Briggs model number it is a 1972. I haven't decided if I want to sell it or keep it. What would someone pay for this? Do people collect Jacobsen mowers? This thing is pretty neat.
