Mark, you are contributing at least as much as you are getting around here, and your cases go on record to help other people, so you are adding value to the site. No thanks are necessary.
For people who are used to pre-emissions Briggs engines, becoming accustomed to modern carburetors takes an effort. Fortunately the Keihin carburetors used on OHV Hondas, and even the Ruixing copies used on chondas, are decently designed and made, so once you make the mental adjustment it is all straightforward. Remember though, that main jet was drilled to 0.55 mm at the factory. My own GXV140 was a bit gummy when I bought it, and it took some work using the old elbow-grease methods to get a 0.45 mm torch tip cleaner through it. At that point it ran reasonably well - just about faultless except it required choke for about 20 seconds after cold start. (There was also an extremely slight stretchiness when the speed was increased, but you'd have to be an experienced car-evaluator to detect it.) So, I gave that main jet a single blast through its throat with carb cleaner, and it opened to 0.55 mm. Ever since then, the choke can be opened completely the moment the engine starts, even in mid-winter.
I think you'll find that some of your emulsifier holes are still blocked, and the remainder are well under-sized. One of the tricky things about carb cleaner is that it doesn't do much when sprayed on blocked holes - it has to flow through them to have its proper effect. Have you watched the video in my previous post yet? The guy isn't kidding - you need to follow that procedure to get a perfect result first try, with Keihin carburetors. It is quicker and easier just to clean the carburetor properly, than to mess about doing the job three times and curse everything and everybody in between tries.
When I started with the Hondas I resented the cost of carb cleaner. My first can cost $8 from a speed shop - but it took me a year and a half to empty it. Then I bought 12 cans for $53, and I'm pretty relaxed. 12 times a year and a half is 18 years. I'll be quite chuffed if I'm still above ground at that point. Managing the underside of daisy roots requires little or no carb cleaner.
I'll move this thread to Tech Talk.
