Abstract: A compact portable electrical generator powered by a gas fueled internal combustion engine. A combined starter and generator is coupled to the engine for starting of the engine and for generating electrical power when the engine is running. The engine includes a lubricating system including lubricant that is supplied from a separately insertable lubricant cartridge and which is pumped by a hose compressing type of pump so as to insure adequate delivery of small amounts of lubricant regardless of the orientation of the unit and also so as to insure that lubricant cannot leak from the system when the unit is not being operated.

Abstract: A number of embodiments of air cooled compact power supplies having air inlet and air outlet openings in the lower portion of the housing of the power supply. The interior of the power supply is baffled so that the air flowing through it must follow a serpentine path to prevent air entrained foreign materials from impinging upon the engine.
