Its not a difficult job to see if the springs are broken. Checking does not alter the settings on the carbs….
To check, remove the fuel line by undoing the 14mm Banjo bolt (while its out see if there is a filter inside the banjo and check its clean) Then take off the central top cover held on with the wing nut, and remove the 5 screws that hold on the top cover of the carb
Lift the cover gently so as not to damage the joint/gasket. When its off you will see a single 10mm brass disc at the back of the carb with a couple of slots. This holds the spring in place. If you can lift it easily then the spring is broken as it’s the spring that holds it in place. If it comes out with the spring attached then the bottom eye is broken, if not then you have to try and fish the broken spring out with a bit of bent wire, its not too difficult. If the disk is held firmly in place, the spring is OK.
I would however always advise that the internal Weber springs are replaced by external ones. I have seen quite a few cars damaged over the years when the throttle sticks open at the wrong time! Mainly on rally escorts, but also a couple of sevens…
