Four-stroke pull-start OHV gasoline engine Air-cooled gasoline engine 

OHV overhead valves reduce carbon buildup, simplify cylinder head inspections, and eliminate the need for electrical contact checks on the external transistorized ignition system. Simple equipment and high dust resistance further ease maintenance. The housing, crafted from advanced hard alloy, delivers high-efficiency mechanical sealing, rapid heat dissipation, and exceptional wear resistance for extended service life. The slim hand-crank recoil starter achieves a lightweight, compact design that maximizes equipment versatility. Equipped with a pressure-relief mechanism, the recoil starter enables effortless starting even for female users. One portion of fuel, twice the output. Advanced energy-saving technology automatically adjusts engine speed based on load size, controlling power output to significantly reduce fuel consumption.
