Hondas can be complicated, not having put one together personally I dont know what seals etc are used. If I were to buy a new mower I think I would go a kawasaki engine on a push mower these days, maybe kubota, some hondas are now made in china as well unfortunately.

One of my corollas is pushing 39 years of age and I wouldnt hesitate taking it anywhere in the world if it were one long highway, I wouldnt see any hyandai lasting that long, letalone any modern car, its currently being freshened up bodywise but the engine still remains unopened apart from a regular tappet adjustment. Doesnt even have a drop of oil on the outside of the engine lol
