wolseley goveners

can any one tell me how these work , its just looked in the valve viewing area and it just looks like a threaded bar, with a bent piece of metal on the end, is this right or has something dropped off

It,s hard to Explain there should be a brass shaped rocker thing in there, when you took the plate off with all the Wolsley writing on in frount of you there should have been a nut and bolt for ajusting the govner weights.
This is hanging on a bar at the top.
the scew in knurald bolt is connected to that and when you turn it clock wise it should speed the engine up,it opens the govners up.
