Manual chuke upgrade/what kind of carburetor is this?

Hi it is about a 4 T China scooter (znen) Will convert my e-choke to a manual chuke… but cih doesn’t even know which carburetor I have, there’s nothing on it, is a replica too.. but is that a dellorto ? have this carburetor:https://www.quad-company.de/…metal lid-forer-139qmb-qma-4-takt what is that? CVK? PWK? Dellorto? Keihin? and would one of these manual chokes fit on it? : two:https://www.racing-planet.de/…-dellorto-gasser-p-244848-1.h tml?…https://www.quad-company.de/…/choke-manuelle-umruest-kit-arreche has someone done something like this before? because I’m surprised that with all the manual chokes the needle is missing on taps…. that can’t fit…. love greetings
