Looking closely at your pics I can see that the electric choke is still fastened on by the rivets so you'll have to chisel them off or drill them out and replace them with screws. That may involve tapping threads in the casting also. I also notice that the casting where the idle mixture screw is housed is chipped on top. Have a look in there with a flashlight and make sure you have a flat head screw slot showing and not just a small hole. If you don't have an idle mixture screw she'll idle at about 1500 rpm and will diesel when you turn off the ignition. You can get a choke conversion kit to change your choke over to a manual choke if you don't want to bother with the automatic one.
