These are for sale by a friend of mine. They are basically "new" engines. They may have been run for testing purposes/factory checked, etc. May or may not have the original box. You can be assured that they have never been on a mower/tractor and been abused. If interested, contact me by e-mail or PM, and I will connect you with my friend. The rest is between you and him. I'm just listing these for him and making a heck of a deal available to some members here on LawnSite.
