I tore down my List 4711 (Holley 4165) for a rebuild and found that there is a crack in the base plate at one of the mounting bosses. Its clean and hasn't gone through but it's obvious the base won't seal correctly unless it is fixed. Does anyone know if these base plates are cast aluminum or zinc? If aluminum I can TIG it, if zinc I'm going to have to go about it differently. I'd like to take a swing at fixing this carb because it is a period correct replacement for the TQ and was on the car when I bought it, but too gunked up to run.
