This L-head engine is no longer made. The newer overhead valve engines have the same mounting, but the engines are about 2" wider and 2" longer than the flathead engines (non overhead valve). The muffler will be on the opposite side of the engine. You can check out our engines to see if one of these engines would work for you. However, since we do not have the unit here for testing, we cannot guarantee if this option would work for your application.
