Hi

How new is the mech ?

Have you checked of the hanger is not bent ?

This may help

very good video thanks for link.I think my problem is the fact that all my bits are old and worn.There is a tensioner is at the mech end on my bike

A worn mech and cables can make indexing difficult

Your tension-er works the same way as the newer mechs that have them on the shifter

change the cable first and see if that helps, before shelling out on a new mech
