I just bought two brand new single cylinder Wisconsin Diesel engines that were made by Ducati, anyone know anything about these? They look to be 9-11 horse power, cute hand crank models. They have a small taper output shaft about 1.5" long, and 3/4-1" diameter. I will be needing a coupler so I can use them on a small Diesel Motorbike. Any help or ideas?
