The ball barely bounces off the round rubber bumper at the upper left of the top arch.
Dead bounce off the top-arch rebound rubber
Cause: The 1-1/2 in rebound rubber wheel has hardened with age.
Checks
- Press the rubber; it should be soft and springy, not hard.
Fix
- Fit a replacement rebound rubber (the original may be riveted, so you may need to re-rivet or use a bolt).
- Or stretch a mini-flipper ring around the old rubber to restore its spring.
