Factory recommended .035 with the weak point ignitions of the time. If you have upgraded to an electronic ignition, you may find a small gain in drivability, mileage, and performance by opening up the plug gaps to .045-.060. Any difference will be very slight unless you were experencing alot of fouling and/or misfires with points. If you still have points, go with the factory setting.
