What's the biting point like? If that's fine then leave it alone.
I don't know the MGA master but on the MGB the master piston comes back
to the circlip in the bore and positions the resting position of the
pedal, and that determines how much 'throw' you have at the pedal, the
slave cylinder and hence the release bearing. Slop in the linkage at
the pedal puts it closer to the floor and results in less slave piston
movement and hence a lower biting point. The same is not true of the
linkage at the clutch end as a spring inside the slave cylinder pushes
the piston out to take up all the play at that end, and more importantly
to compensate for the graphite release bearing wearing down. The more
that wears the further the piston moves out, drawing fluid down from the
master reservoir, so you continue to get a full stroke of the release
arm. That makes the MGB clutch system self-adjusting, and there is no
scope for threaded adjustment anywhere in the system. But as I say that
is the MGB not the MGA.
