When you get the car to run, spray carb cleaner around where the manifold meets the block and carb to manifold. Try not to get any directly into the carb intake. If there is a vacuum leak in those areas the engine will stumble then recover. Where are you setting the GVA? How many turns out is the air needle adjustment? I set mine 1-1/2 turns out to start with. The idle circuit is fed from the well, are all the holes in the well clear? They are on the small side. Did you take the well out when you cleaned the carb? It could be plugged up.
