after looking at the teardown,can you confirm that
-
when you twist the throttle the 'cylinder'(slide) with the needle moves inside the carburetor? The throttle action is to lift the slide to allow more air in, and to lift the needle in unison with the slide to allow more fuel in (bigger opening = less pressure drop, so we need larger fuel opening etc).

You state that the moped engine idles, but dies on opening the throttle - I could only imagine the needle stays down when the slide opens, and -like on idle - only just the idle circuitry supplies the engine with fuel
