Early Porsche 911 trip odometer reset cable

Early Porsche 911 trip odometer reset cable.
There is a small torsion spring that facilitates the return
on the knob.
The spring on mine is broken, however will the reset still function ?

Someone must know the answer ,come on guys

I can’t see that it would not reset, gravity will (should) hold it down but if anything may not allow the trip odometer to calculate fully?
Don’t know until you try it.

I thought the spring was to there to prevent turning the knurled knob in the wrong direction.
