5000/6250 watt Coleman PowerMate generator. 10 HP Tecumseh pull start, 4 stroke gas. (Premium Unleaded...not AvGas) Has been stored indoors all its life. Tuned up and oil changed in February 2020 to ensure it's running fine. Has been run approx 1 hour per year since new, and gas stabilized. Bought in anticipation of power outages, but have decided to go with whole house LNG standby generator.
