PLEASE READ ENTIRE ADD. Used Kohler 25 hp command proengines. Shaftsize is 1 7/16. Shaftis 4.5 long. The keyswitch may or may not work they generally need to be cleaned out with electricmotor cleaner. Thestarter may work but need the brass bushing in the Bendix. If youwant an engine that is ready to bolt on looks new and is ready to run this isnot for you. I donot have exhaust for these. These engines have been retiredoff asphalt saws and have around 300 hours on the clock they need to be cleanedup this is going to take some work it is asphalt dust that has Been cooked onthe fins and exterior surface of the engine. The best way I have found is tobring it to someone with a JET CLEAN parts washer. The cylinder bores are generallyin great shape. Valves and valve guides are fine. The rings in these wear out tothe point where they have a 1/4 to 3/8 end gap and burn guite a bit of oil. If you need a engine like thisfor a good price and can do the work it is a great deal you can message me withany questions. The item “Kohler CH 730 Engine” is in sale since Wednesday, June 27, 2018.
