Very clear and detailed video that really makes it easier to understand what is entailed with rebuilding the carbs. Thanks for sharing your work.

How did they wind up functioning after being installed on your vehicle? Thank you so much for posting this video!

The only part that needed further attention were the dust seals (shown at 1:47 in the video) I had to remove them and open up the hole because they were gripping the shaft and stopping the butterflies from closing quickly. I clamped them between pieces of wood and drilled through. You can hear the engine start up in this video kzbin.info/www/bejne/nnrPZ3-nlLVmn8U before and after tuning. We used an airflow measuring instrument to check and balance each carb and then set the idle mixture using a colour-tune spark plug having made sure the ignition timing was also set correctly. You'll hear a little bit of popping in the exhaust which was air leaking into the exhaust and was resolved by tightening the exhaust manifold. So far the car feels good.
