1949 chevy 1/2 ton pickup with a 1954 235 engine. Not sure what make this carb is, it has an auto choke and I would like to restore back to manual choke and and add a hand throttle control. Can anyone identify the carb from my pictures, and how to revert back to manual choke, etc? Link to the pics is http://www.picturetrail.com/gallery/view?username=psy999&x=18&y=4

Thanks
