Gottlieb Outer Space the thousands reel gets to the 8 and 9 digits and doesn't move beyond that for several "clacks". I see how to remove the assembly to inspect it and clean a few bits of it that I can reach, but how do I get to the plunger and take that apart to clean it? The plunger clicks fine on every other digit but it gets spongy/lazy at the 8 and 9 digits and only plunges about 80% of the way into the coil unless I apply extra pressure to finish its full range of travel. The pinrepair site is fine for an overview, but those old 640 x 480 pictures are hard to see much detail.
