Spring-loaded Float needles, why?
 
Some bikes have them, some dont. What is the purpose of the little spring loaded tangs, pins, and balls on the end of some float needle valves? Why do some carbs feature them, and some don't? What do the exactly do?

Bumpy roads or terrain cause the float to bounce. The spring-needles keep the
bowl from overfilling due to the float bounce....

The springs also keep the needle tip from pounding itself senseless against the seat.
