You're not adjusting something right.
Loosen the cable all the way. Loosen the throwout adjustment lock nut and turn the throw out adjustment screw all the way out. Now set your springs according to the manual and try to make sure to keep them even, wherever you choose to set them. Use a ruler or calipers to verify they are set so the pressure plate is parallel to the clutch plates. Now turn the throw out adjustment screw in until you feel contact give it another 1/4 turn and lock the throw out adjustment nut. Now adjust your cable to take most of the slack out of it.
You want a bit of free play in the lever to preserve throwout bearing life.
If it slips, give each stud another half turn on the spring retainer plate
You may have to add a clutch tamer if it wants to JUMP on release.
sorry for the edit, been at the track all day, high on nitro and burnt rubber
