Not a WD I'm afraid, but does anyone know where I might find valve guides and valves for a 1933 W33-6? Also, a the clutch adjuster scree that goes in the clutch actuator arm would be good.
If the screw you are referring to is what BSA call the Control lever Thrust Pin, 25-4251, which screws into the clutch arm and sits against the ball bearing in the arm, you might find that Russell Motors have stock.
Otherwise, maybe you could make one out of Silver Steel and flame harden it?
