Check these points because you may just be physically using one or two coils from the spring and not the whole thing!
I learned the hard way during my experimentation of the clutch on the 705. I used to use the super hard silver spring from *spit* on my 705 clutch. Like you mention, it binds and it's like 1 or 2 mm longer than the stock (can't recall, getting older
). The performance was very hard to predict. Sometimes it worked good but other times not. So best would be to stick to Serpent Centax springs in Serpent Centax clutches. The 1.8mm Centax II spring does wonders on the Centax 3.
