I had that same genset. My Kohler parts manual says that part number is A-241366.
Like many Wisconsin tractor and motorcycle manufacturers (Harley Davidson), Kohler used magnetos made by Fairbanks Morse in Beloit, Wisconsin.
Many of the internal parts are interchangeable. Rather than trying to find a used or rebuilt mag, you might want to try to
identify and replace the faulty subpart. These magnetos contain the coil, points, condenser, rotor and distributor cap.
Typically, the condenser will fail or the coil windings will burn out or the points will wear out. Replacing just a faulty
coil, points or condenser might be faster and a lot cheaper.
Try this site:
www.magnetoparts.comThere is a service guide posted there for a much earlier mag but it is similar or identical to the inner workings of the mag used on your Kohler.
Do you know what's wrong with the mag?
