There could be a couple of things wrong. First, how is your N2 pressure
to the 430? If it's too low (below 60 psi), then the ejector arm could
malfunction. Second, there is a part called the "positive ejector" that
is pushed up by the ejector arm when it is ejecting. It's a little
black-colored piece of metal. If it's sides are notched or rough, the
ejector arm could be hanging up on it. Take a piece of sandpaper and
smooth it out. Good luck!
