THINK MY CLUTCH IS DIEING

[dogfather]

hi guys just wondering how to diagnose a dieing clutch, it is very high i only need to press down about 1"- 2" and it will start to disengage and i do get a slight smell of what i think is clutch burn and even more so when i turn the heater on. Does this sound like it needs replacing? thanx agen..neale..
