Hercules 6cyl engine - (Pembroke NY in Rochester, NY

I have a older Hercules engine. The engine was used as water pump or generator?? I don't know if it runs or not just for parts. I have the other piece of manifold attached to a muffler pipe. Just top of manifold broke a easy fix. These engines are very rare & hard to find parts for them. Model # JXB & Engine # [removed phone]. Call [removed phone] Thanks Pau
