Thermoquad vs square bore

I had problems with my Thermoquad, when I first bought the car.
I really didn't like it, constantly bogging. This was mostly due to the car being rarely driven.
So I paid some good money to have a local speedshop rebuild it for me, then I really "Hated" it, so I took it off and took it apart, with the help of a manual I rebuilt it myself.
That's when I discovered how the vacuum secondaries worked, and how to adjust them.

Now I would have to say, it's the best carb I've ever had.
