Thermoquad running rich

I love the TQ.
IMO, she is the most versatile factory street carb ever designed.
Ok lemmee qualify that;
IMO, the most versatile carb I have ever owned or worked on. Just two carb-sizes covers the entire engine line up from the 318 to the 440.
To do what just one TQ can do, I think you would need a fleet of PV-equipped Holleys.

Three sizes. 800, 850 and 1000.
