It's always trial & error with Campy older stuff most of the time.
Is the rear shifter in decent shape? cable & housing are well lubed?
Currently, the 9s chain is slipping on campy 8s cassette. The derailleurs and shifters are in great shape and everything is brand new and well lubed. I'm thinking of trying out an 8s chain but there are no campagnolo 8 speed chains available.
