Those are jets that are debris free and clean?
How did you "clean" them?
Did you clear fuel-circuits which delivers petrol to jets?
It's like garden hose with spray-nozzle at end. You can clean spray-nozzle all you want, but if there's something clogging along hose, you won't get proper spray volume.
There is absolutely zero fluid that you can soak that will dissolve dried petrol varnish. It's basically plastic. Only way to clear is mechanical reaming and flossing with appropriately sized strong wire. Cut guitar wire at 45-degree angle to make tool for clearing out holes. For example, every little bleed hole in emulsion tube and pilot jet needs to have matching-sized wire pushed through to shove out plastic plug of dried fuel. I'll even drip Kool-aid through end of those and verify that every bleed-hole "bleeds" out properly.
As shown in photos above in post#14, you also need to floss out holes that lead to venturi of carb as well (green dots). That's where fuel flows after it leaves jets.
Please see following links for more details and photos of what needs to be done.
