where am I going wrong?

OK , wow thanks for all the great responses first of all I didn't know anyone was using any clutch other than a diaphragm that's the only one I found ? That being said it IS a diaphragm clutch and it DOSE have the heavy duty spring in the pedals but I had a spare set of pedals with the same spring so I didn't know if I could remove it but it did cross my mind so...if that's what every one us doing I will take it out hopefully I can do this with out removing the pedals from the car?
