Yep. the older Honda's are all Japan but for many years now, they have been made in China. The Mowers have a sticker on the rear of the motor stating such. Most carbs are chinese anyway. Things have certainly changed.... Workshops are overseen I'm sure from Japan. I have an old Pope (Chinese) Line trimmer. Starts every time. Never drained fuel Is 9 years old now & you cannot kill it! I believe it depends what chinese company are involved. There's much cheaper crap out there but also, pretty good also nowadays. The older Japanese made stuff is tuff....We've got three old Honda's, all of course say made in Japan. My Honda genset was definitely made in Japan, it even has an old Honda Car Land sticker on it from the 80's. My Kohler v2 24hp says made in China, load of crap, but it runs well. American companies need to wake up.
P.S. When the Honda carbs block, you cannot simply spray carb cleaner in them & be done, as you can get away with with B&S. That's why I don't hassle with them anymore & prefer to just replace with a cheap carb as most are getting old now & have been well used. Definitely would not pay for a genuine Honda carb as it's price would no way be an option for customers.
