Does Anyone Have a Keihin Carburetor Cross Reference?

Long shot, but I figured I'd ask... trying to track down a replacement carb for an old Honda single-cylinder, four-cycle, horizontal-shaft engine. Unfortunately, all I know about the engine is that it's a Honda; all the markings are gone, and I'm guessing it's around 8hp, but it could be anywhere from 5 to 11. The carburetor is a Keihin, but the markings (images below) don't come up in any search I've done, to tell me for sure what replacement carb I need.

It looks identical to this, but I don't have sizes to confirm this is the right one:


These are the only markings:






If anyone can point me to a definite replacement unit, rebuild kit, or cross-reference number, I would really appreciate it.

Thanks!

Thanks, found that, but it doesn't help me narrow down (That I could see) options for a replacement for this, or a rebuild kit.
