I have exactly the same problem, I bought the car 3 days ago and the bite is right at the top, and when I change gear I can smell the clutch burning, it is definately, as "T" and "Colin" said, time to buy a new clutch, you can get them from salvage yards a lot of the time though, so its not always that expensive, make sure you dont buy another naff one though!!
