Randy, here is my two cents! If you are looking for marks on the flywheel you probably have a back ground with snowmobiles or motorcycles. These older outboards, the actual timing changes every time the tiller handle is twisted. Many members here go to great lengths to get the cylinders firing 180 degrees from each other. I have found if you are diligent with a feeler gauge you can make these motors run very well!
