ONAN Generator 4CCK-1RV 4kw 120/240 60 hz LNG Carb used takeout from Fire Station. Was running when removed.This version has a carburetor that accepts Natural Gas (LNG), or Propane, I'm not sure which fuel (probably LNG based upon the size of the fuel line). Converting to gasoline would require a modification. This is a used takeout from a city Fire Station. Running when removed. Complete. Rotates smooth and easily.Guaranteed to run, but probably is high time and could use rebuilding.This one is the exact 4CCK unit in the photos and totally enclosed in a clamshell case.
