Each time my 8HP Honda has had similar symptoms it was cleaning the low speed circuit that fixed it, sometimes just be removing the low speed jet and cleaning it.
At Honda school they tell us never to soak honda carbs in Carb cleaner because honda puts a clear coat on the aluminum and depending on how corrosive the cleaner is it can deteriorate the coating. The highly promote the use of an ultra sonic cleaner.
Now I don't know exactly what harm it does and know plenty of other techs that do it but just relaying what Honda said that one day in class

I can see Honda recommending that. Seems like once the clear coat is off everything will be OK. I'd be looking for a cleaner (most do) that removes paint.
Soaking disassembled carb in acrylic thinner for 15-30 minutes, then rinsing with generic carb spary works very well. Its a good practice to consume all fuel on carb(s) while engine is being flushed, specially 2 strokes engines.
