W108 inlet manifold

[COLINMB]

Hi, I've just bought a 1969 280s W108 and working on some carb issues. I,m curious about the balance weights sticking out of the inlet manifold which I can see are linked to some sort of flap assembly. See bottom right of attached image. The weights seem to be solid or ceased. Should they be easy to move and will this affect the running of the engine? Any advice appreciated.

Just wondering did you ever find out what the weights where for.I have the same car imported from south Africa.Thanks

Pontons have same items, they are carburettor heaters for cold start and always rust solid. Unless you going to drive the car at something like -20deg just leave them alone.
