Thanks. I'm not sure about this engine. It has a lot of differentiates from others I've seen. The platform is wood with metal sheet on top. But I sure it's not the original. I've noticed this one has crank guard that I haven't seen on other engines. The mount for the crank guard is cast into the base of the engine. So I'm sure it is original. The govner base is the same styling as the throttle valve base. So it would seem it's original to the engine.
