You fail to mention what kind of carburetor you had, if there is a speech shop in Albuquerque they will sell a profile Kit for your carburetor, which will come with a variety of jets and everything you need to set it up, if there is no shop you can either get online, or go to a real parts store and they will order the kit for you. It will come with the charts with specifications for your altitude.
