Auto Temp servo unit help

[ImperialLeBaron1969]

Unfortunately, I can't really help you more with that since I abandoned my ATC system long time ago in favor for a modern Vintage Air system.

Your pics solved a lot of my problems. Now the unit runs and changes between AC and Heat. There was a big vacuum leak between the carb and the unit. And the vacuum hoses in the servo was not in the right place. There are some issues with the vacuum switch, but thats not a big problem.
