A Compact blower is provided having a housing defining an engine compartment, cooling air compartment and a volute chamber all coaxially aligned along a vertical axis. An internal combustion engine is oriented within the engine compartment with a vertically aligned output shaft and a forwardly facing fin cylinder. The rotary impeller is affixed to the engine output shaft provided with a plurality of cooling air pump blades projecting upward from a circular disc and oriented within the cooling air pump compartment. The impeller is further provided with a plurality of blower fan blades which project outwardly into the volute chamber. The rotation of the impeller causes air to be drawn into the volute chamber and discharged through the blower air discharge port. Cooling air is drawn through the cooling air pump compartment and directed across the engine and cylinder and ultimately discharged through an upper front portion of the engine compartment in a direction away from the operator.

Engine arrangement for blowers and blower/vacuums

A first and second baffle formed of a thin sheet metal material are introduced into an engine induction system on the upstream side of air fuel metering device and interposed between the air fuel metering device and a tubular intake runner in order to prevent post engine shut down fuel boiling. The first and second baffles absorb heat from the induction system and dissipate heat to the surrounding atmosphere. The first and second baffles are sized sufficiently large to limit peak fuel temperature in the fuel metering device 130&deg; F. when a hot engine is shut down in a 70&deg; F. environment.
