Are you sure the tach is reading low ? Reading high is the usual malady ...
and AFAIK replacement (either of the whole head or of the flying magnets
inside) is the only cure for reading low.

One possibility is that it was installed backwards ...

Actually, excess motion at the slave without fully releasing is exactly what
you would expect with a broken pin. Other possibilities include a pilot
bearing that was damaged on installation, and the friction plate not sliding
easily on the splines due to rust or a burr somewhere.
On a related note, has anyone tried fitting a smaller i.d. slave cylinder to
a TR6 ?
