Carb Issues

Ok, the new to me 72 Dart I just bought has yet another problem.
The carb is a Holley R8448 4095918 3328 2 Barrel. Looks to be that the choke does not work, maybe missing a spring and the guy has a Lokar kick Down cable but it's not installed on the carb. Car runs but needs to warmed up for at least 10 min before it sorta idles. What should I do? Fix or replace. Buget build so if any one got something for sale let me know, Just want to ride my car. Any info will help.
