The clutch return spring should hold the clutch pedal up against the rubber bumper on the pedal support (Assembly Manual, UPC 7, sheet C2, item #9), then adjust the lower fork pushrod to get 1" to 1-1/2" of pedal free play between the full-up position (against the bumper) and the point where you feel resistance when depressing the pedal (throwout bearing contacting the clutch fingers).
