Clutch Adjustment Issues

[markw 1]

I am having issues adjusting the clutch on my sprint car, it has a steel flywheel and a 71/4" helix clutch,

I have changed the plate and the cable this week and it is a bit better than before, but still to get the clutch to work it's very stiff and very low to the floor

When you slacken the cable off to get a nice "springy" pedal you simply can't engage gears at all.

 

Any ideas what the issue is, or what to try to improve it, is it a cover assembly diaphragm issue or is something wrong with the clutch arm or fork?

It's an AB motorsport hybrid gearbox thingy, and is freshly rebuilt somi don't think its a box problem..

Thanks
