Abstract: An internal combustion engine is provided. The internal combustion engine includes at least one cylinder head and at least one exhaust pipe having at least one flange, whereby the flange has at least two flange fastening holes that have at least two fastening screws for fastening the exhaust pipe to the cylinder head of the internal combustion engine, whereby the exhaust pipe can be arranged so as to be connected to the cylinder head by means of the fastening screws in such a way that it can be dismantled, whereby at least one centering device is provided essentially in the area of the flange holes.

Abstract: A manual starter crank has an integrated safety device providing protection against backfiring during starting of an internal combustion engine. The manual starter crank has a starter shaft which, when turning in a starting direction, engages the free end of a cam shaft of the internal combustion engine. The safety device is integrated into the casing of the manual starter crank and includes a ratchet with a pivot axis which is approximately parallel to the starter shaft. In the engaged position of the ratchet, a free end thereof engages an abutment surface on the starter shaft, whereby the manual starter crank is connected in torque transmitting relation with the engine cam shaft when the crank is turned in a starting direction. The safety device includes a disengaging bushing surrounding the starter shaft and which is mounted on a bearing support by a one-way clutch and presents a disengaging pin in the path of movement of the ratchet.
