The diverter valve is installed and the cooling system is filled, so far with no leaks. This set up really makes me want to transition to triple webers...

The coupe has been running rough lately so I decided to adjust the valves (two were slightly loose), check the timing (just a hair off), and check the carburetors for vacuum leaks. The front carb had developed a significant leak and was causing the lean misfire.
I hooked up my O2 sensor and then pulled the front carb off. The bottom was no longer flat, so I trued that up and did the same to the phenolic spacer and put it all back together. Still leaking, so off it came again and I called Pierce Manifolds for teflon throttle shaft seals for both carbs. I just installed the seals and fired it up for the first time and the leak is fixed, idles better and O2 readings are back where I would expect them to be.
Tomorrow will synchronize the carbs...
