Abstract: An internal combustion engine has a base. The base has exterior and interior faces. The exterior face has a starter. The starter initiates rotation about a fixed horizontal major axis of rotation. The interior face has a power output shaft. The power output shaft is adapted to be rotated about a fixed horizontal axis of rotation coextensive with the major axis of rotation. The power output shaft has a free end. The free end constitutes a power take off shaft. A driven device has a power input shaft. The power input shaft is mounted for rotation about a fixed horizontal major axis of rotation of rotation coextensive with the horizontal major axis of rotation of the power output shaft. A coupling member couples the power input shaft and power output shaft.
