You probably know this Mark, but the rows of tiny holes in the emulsifier should be checked individually. My way to do that is, after treating with carb cleaner and blowing out with compressed air, I push the correct size of jet drill bit through every hole in turn. I do the same thing with the main jet of course, and the idle jet ("Pilot Jet" - black plastic item, directly under the idle speed screw). I don't necessarily remove the idle mixture screw ("Pilot Screw"), if carb cleaner squirts out from the tiny hole near the throttle butterfly.
If that set you have is the rings-and-gaskets kit from Thailand, I don't think the rings will be chromed. I've used the Thailand unchromed rings (which probably come from China) and they worked fine, but after 6 hours use I replaced them with chromed ones just so I'd feel better about the repair job. The unchromed ones should last about as long as they do in a side valve Briggs, which would satisfy nearly all private users. (Original Honda GX/GXV engines have chromed top rings, though only the late production ones had chromed, steel rail oil rings. The older ones have plain cast iron oil rings, which wear out after say, 3 years of contractor service. Chromed steel rail oil rings should last considerably longer.)
