Zongshen RX3 carbureted version mods & repairs

How difficult would it be to convert the POS fuel injection system in the US models to work with a carburetor? Complete re-wire? Or can the ECU run the ignition while the carburetor actually properly meters the fuel? And the million dollar question of course is where to get the parts? There's not a lot on AliExpress for any Zongshen bike.

The carb for it is right here:

And here is a CDI:

I have no idea if the existing EFI ECU can run it though, I would be surprised if it does. Most likely you need the ECU and wiring harness for a carbed RX3.
