Up for bid is a New/Used Saito 125 four stroke engine. I got this engine in a plane I bought but I already have a bigger engine for the plane. Engine is in new condition but was broke in by builder of the plane. I ran 1/4 tank of fuel through engine while still on the plane to make sure it ran. It runs great. Engine is for sale as is no returns. It does not have box or instruction manual but manuals can be downloaded for free on net. Good luck and thanks for looking.
