Thank you for all the suggestions. Have opened the idel mixture screws on the front carb, and idle and drivability have improved. But still not 100% satisfied. Will try to play with the idle screws on both carbs tomorrow, and see what happens. In the meantime, I am talking with Scott about rebuilding and calibrating the original carbs. Will keep the Newcomb setup until carbs will be ready.
