Mine is the same except the crosshair moves at the slightest touch. You can see where the freeplay occurs, partly in the lower cup that supports the spring and where the shaft enters the yoke. Yours should be sensitive to the slightest movement too.
When I get time I will have a look at the construction and see if the freeplay can be reduced or eliminated.
