Honda EM6500S Generator with electric starter and pull starter. Used for approx. 350 hours 2011-2015. Has been stored in my shed since 2015. To buy new today: $3500. Review: The 6.2-gallon gas tank isn't the biggest tank available, but the 389-cc engine is among the most efficient non-inverting gas generators. When only using 50 percent of the max wattage, the running time is 7 hours, which is the second longest running time available among the portable generators reviewed.
