ATV fuel switch protocol
I
think it's possible I may have caused some carburetor damage by not
shutting off the fuel switch when we stable her.
Someone once told me you only
needed to do that when transporting, but several comments on an ATV
forum says shutting it off can avoid needle damage.

Usually a fuel switch is there to prevent the tank from draining. E.g. if you're maintaining the carburetor, or if there is a leak somewhere downstrem from the tank.
AFAIK, needles and jets are more often damaged by incorrect maintenance that by normal use. I don't see how leaving the fuel on could damage the needle? Mind you, if there is a malfunction in the float (which stops the fuel flow when the carburetor bowl if full), storing the quad with the fuel valve open could possibly cause the engine to fill up with fuel.
