Older Tecumseh generator. This is a real generator, not to be confused with many of the weenie ones on the market today. It is 4000 watts, outlets for 110 and 220. Very heavy construction. This generator built a mile of horse fence, running two saws and a router. Also ran our fridge, freezer, and lights during an ice storm. It is wired for electric start with a lawn mower battery or pull start.
