I have a couple of 21" Hondas with the hydrostatic drive that are over 11 years old. These engines have the side shaft that drives the hydro trans. These have been about the best trim mowers I've used. Really screwed up and let one of the engines run without oil until it seized. Positive it is ruined as I removed it and looked inside. I really hate to scrap the mower for lack of an engine. Yet you can't get one from most of the suppliers available on the internet. I just don't want to go to my dealer and pay their price for a new engine. Has anyone "rebuilt" on of these engines or does anyone know where I might get one at a reasonable prive? Thanks, Cleve.
