Bought this as a backup power source for the house for low demand (it's not wired for 240V output on a single connector). Right out of the box added oil and gas, and then started on the first pull. The choke must be turned off quickly after starting--or it will run a bit rich and smoky. Put out 124VAC, and output seemed to work ok into a space heater, and 120V 20A breaker tested good.
