[T3] '72 FI won't idle down

[Max Welton]

" When warm - I can put my finger inside the throat of the IAD and totally
plug the inlet "port" for the idle speed screw. This 100% plugging will
result in a 850 or so idle speed (with the idle speed screw still all the
way in and throttle plate still closed)."

Isn't the IAD supposed to close completely when warm? Is it adjustable?
