clutch problems

I got a 66cc 2 stroke engine. Something is wrong with my clutch. When I tighten up the cable with pliers at the arm, the clutch feels stiff but slips. So
I tighten the flower nut where the clutch pads are all the way and it stops the slipping but now my cable is loose and my clutch feels soft.

And then If I tighten the cable again it will feel good again but slips once again? The only way its working is if I tighten the flower nut all the way and leave it soft but it seems to be getting softer and sometimes I can stop my bike? I

I tried to tighten the main spring inside the engine and that didn't seem to help but it was loose if you ask me. I don't know what's causing the problem.

all the pads fit good.

Tomorrow I will try and leave plenty of stack in the cable just to see what happens.

The clutch is working much better now.

I loosened the cable to the point where it didn't engage at all. I know you told me not to do that but after playing with the flower nut I manged to tighten up the cable. For some reason when I loosen the nut, the cable gets stiffer and the clutch lever feels nice and hard. But to hard and it slips. So this time I tighten the flower nut to the point where it doesn't slip. My lever is a lot tighter now. Not super tight but at least it doesn't slip. So go figure ?
