Automatic to manual choke coversion

im looking to replace my automatic choke with a manual ( pull or flip) choke , ayone done this or got any info about this. The motr im using is a piaggio from a skipper st 4t . Would i be able to just change the carb or do 4t motors require a difrent carb from a 2 stroke ?
