Check to see if the plunger is mushroomed, for the idol trapdoor, if
it is it can stay down and let two balls out like you described.
Obviously the whole mechanism, too, but those plungers I've seen
mushroomed on several Indys.
You can often replicate the fault in coil test.
Filing a chamfer on the ends is enough.
Hope this helps.
