Not a bad video, but I was kinda suprised that he thought the accelerator discharge nozzle didn`t look right, but never noticed that it was upside down with the screw. But I have always liked the 3310-1 carbs, been using them since the 70s, including my FE Fairmont drag car,and several FE street strip cars, and will be freshening one for the 428CJ in my 59. Just good all around carbs.
