Clutch pedal spring removal?

[stickk]

New to me '01 F350 CCSB ZF6. Previous owner said he had the clutch replaced with a stronger one but didn't know what brand. About a month after purchasing the truck the clutch pedal stuck to the floor and I couldn't shift gears, luckily I was close to home and got it back. Fooled around with the pedal and thought I could hear air leaking in the master. Bought a full assembly and installed and all is well.

Well I don't care for the action of the pedal, it just doesn't feel smooth. Would removing the pedal helper spring help? Also, if I shoot some WD40 on the rod that holds the pedal to the bracket it seems to help but is short lived.

Well I took of the spring to test it out and to me it is a lot better feel to the pedal and clutch engagement.
