Probably a poor choice of words.

Don’t have the tools to tell the rpm, however, outlets inside giving 112-115 volts pretty consistently.

Luke, that Onan should not idle. It should run at the governed speed that
produces 50-60 hertz and around 124-130 volts AC at no load. Somewhere
around 1750 rpm. Might sound like idle speed compared to a Honda or other
late model generators. DO NOT REV IT UP BY PULLING ON THE GOVERNOR LINKAGE
WHILE UNDER LOAD, IT WILL FRY WHATEVER IS PLUGGED INTO IT.
