Honda mini melody carb parts

Hi all, I'm looking for some help finding parts for my scooter. Plz be gentle, as this is my first post

I bought a '86 Honda NT50G Melody mini from the local autojumble last year. It seemed like it wouldn't take much to get running as it turned over and had spark, however the carb needed a clean, which I did. Only problem was, the 'enricher valve' (small brass choke slide inside the carb) was stuck, and a previous owner had yanked too hard on the cable (it's a manual cable driven choke with a lever on the handlebars, rather than an electric one) and broken the cable mount off it.

I eventually managed to remove it by screwing a wood screw into it and pulling it out with a slide hammer, but Ive had no luck finding a replacement. If anyone has the correct enricher valve or a whole carb they'd like to sell, knows where I might find one, or even just knows the model of carb (it's a Keihin, but I don't know size or anything), t
