650 Watt Honda quiet generator. Used gently for work. Handles one tool well -- or two smaller tools like sanders. I did a grinder, skill-saw or small Bosch rock-drill with solar installs. Recent service by a marine mechanic -- full carb-clean, new gaskets and tuning (govenor, voltage & frequency), new air-filter and plug. Runs like new. 76cc motor, 48lbs http://cdn.powerequipment.honda.com/pe/pdf/manuals/31za8810.pdf
