Oshkosh and Wiscona Pep Engines

Many of the best-known engines came from Wisconsin. So did many of the least known, including the Oshkosh and Wiscona Pep.

Allen doesn’t know the engine’s exact output, but pegs it at around 4 hp based on its bore and stroke of 4-3/4 inches by 6 inches. A closer view of the Oshkosh’s crank and flywheel-mounted governor assembly.
