Thanks for that AVB. It certainly wasn't rambling, it was exactly to the point.
I normally recommend removing the main jet, emulsifier, idle jet if detachable, and idle air bleed (mixture adjustment screw) when cleaning carburetors, and do it that way myself. However there are two issues that arise with the emulsifier in particular. The first is that hard gum formation may make it difficult to it get out without damage. The Keihin, Ruixing and so forth carburetors used on Honda and chonda engines frequently have this problem. The second issue is that a few carburetors, including one that was used by Tecumseh, simply have pressed-in non-detachable emulsifiers, which foul up after a time and are quite difficult to deal with. It would be nice to find a simple, non-polluting, non-damaging way to deal with those problems.
Incidentally there are Chinese-sourced overhaul kits available for the Honda-type carburetors. Here is an example of one:
