The engine is of a type including a heat shroud for directing cooling air about cooling fins of the engine head, the shroud having a top wall provided with an air intake opening located above a blower or fan of the engine. The hood and opposite side panels cooperate to define air inlet openings at opposite sides of the enclosure, the openings being located at a level above the top wall of the shroud. A deflector or baffle member is provided for preventing hot air exiting from the shroud from recirculating through the intake opening of the shroud.
