Well, I have always bragged about how good my Honda 21" wb mowers are. Finally had one of the engines (about 10 yrs.old) fail. Believe is something really bad inside (crankshaft, etc.). Seems that none of the major catalogs list an engine for this mower. All the Honda engines say "not for Honda mowers". Guess is because of the side shaft that drives the transmission. Has anyone else replaced one of these engines? Will I have to go to my local dealer for this? The way they charge for other parts I hate to ask about an engine. The rest of the mower seems to be in such good condition along with having the hydrostatic drive that I would like to replace the engine rather than junk it. Thanks in advance, Cleve.
