If the fuel line is very old, and was stored dry, there is a good chance they've collapsed and/or are feeding crap down into the carb. I suggest you consider replacing the rubber hoses asap, and before going much farther, either remove the carbs for a good cleaning, or walk through the in-situ carb cleaner process.

Also, although I have a set of 40ADDH carbs out in my shop, I've never really studied them. I suspect they use a diaphragm accelerator pump. It is quite likely that they have perished after being stored dry for so long, then asked to perform regular duty with gasoline. If they are similar to other Solex accelerator pump diaphragms, they should be easily accessed on the bottom of the carbs after removing same from the car. I'd say those were highly suspect on the DOA list.
