Here is a real nice original diecast magneto gear for a Sparta Economy hit and miss gas engine. It measures about 2 3/4 inches in diameter with a 1/2 inch face. It has a 3/8 inch keyed hole for the magneto armature shaft. It is about 7/8 inch thick through the bore. It has 20 teeth and they are in great shape. They have very little noticeable wear if any at all. This gear has no cracks, breaks, or repairs of any kind. It looks to have hardly been used and is ready to be put to work on an engine. These original gears are getting pretty tough to find. Don’t miss it.
