You can check the operation by working the air cylender
manually. With no pin the shutter should open when you push
the cylinder up and close again when you push it back down.
When the pin is in there is a toggle effect. Pushing the
cylinder up will cause the shutter to open and close
quickly. Pushing it back down will reset the shutter. It may
be that you are not squeezing hard enough to operate the
toggle or perhaps there is some leakage at the hose fitting.
Make sure you cover the hole in the bulb while squeezing it.
Its possible there may be something out of place in the
shutter. The mechanism is pretty simple. I've gotten into
Packard shutters a few times to clean them but they are
usually pretty trouble free.
