A power generator unit incorporates an engine and a generator driven by the engine. The generator incorporates a multi piece sound insulation cover that allows for efficient cooling of the various internal components. A plurality of cooling paths are created within the cover and air is drawn into and through the cover by two separate fans. An engine cooling fan draws in cooling air through a generally dedicated cooling air vent(s) to cool an electronic control(unit, an engine cylinder, and a muffler. A generator cooling fan draws in cooling air through an additional cooling air vent(s) to cool an engine crankcase and the generator. The insulation cover provides quiet operation and efficient cooling of the power generator.
