clutch question

The washer idea is great that spring is solid.
My question is why remove it I don't understand how removing that spring will get the pedal to return to correct position.
I was able to use a longer adjustment rod and it helped some but when pedal is pressed to floor you can gear a grinding sound at a loss here.

You didn't read above? It's because if the DECREASED pedal effort IE completely different design between the 2 finger and diaphragm clutch covers. None of these cars ever came from the factory with a diaphragm cover so there was never a provision "for" the linkage.

When you increased rod length you caused the pedal, when at the floor, to depress the fingers far enough to hit the clutch disk. This by the way can damage a diaphragm clutch.
