Plunger springs ?
I thought new ones were N/A ...

Does it matter? The plunger is locked except during tensioning and that can always be aided with the screwdriver-down-the-hole technique.

The chain cuts into the horse shoe near the pivot and burs over the edges. These burrs stop the pivot from moving. There is an article in this months VJMC magazine on the subject.

I found this book useful.
