1966 289 Clutch Pedal does not return.

Just installed a new clutch and brake pedal assembly and when I push the clutch in the pedal does not return. New return spring as well. It is a strong spring like the one that came off. Any tips on how to set up the new pedal. The top clutch rod that attaches to the pedal and the z bar bracket have no adjustment just the lower rod going to the clutch fork has an adjustment.Thanks.
