15hrs on generator. Manufacturer "break-in" procedure followed which is most of those 15 hours.
Fresh oil, only ran premium non ethenol gas in it, new battery fall of 23' that was hooked to a tender when not in use. Comes with everything that was in the box (30A adapter plug, tools, funnel, books)
Starts right up with push button or pull cord. Only thing changed from factory was a magnetic drain plug was added.
Used to run a 30A camper a few times and did so with 0 issues. It is as quiet as advertised could hardly tell it was running from inside the camper unless nothing else was on.
