To decide what voltage the starter is remove it and measure the diameter of the main shaft, 6 volt will be 14 millimeter diameter, 12 volt will be 12 millimeter. Then count the number of teeth on your flywheel to see which starter you need to use. With a 139 tooth flywheel you can use a 6 volt. If you have 168 teeth you most us a 12 volt starter. You can add a starter switch with a side terminal for a resister to use with a 12 volt system to a 6 volt starter if necessary
