Are you setting the timing 'by ear' with the car stationary? I suggest you drive the car on the flat and up a hill, see how it goes. Then change the timing and drive it again. You should be able to 'home-in' on a position that goes fastest but also smoothest. I have done this with my seven, but there are others on here with much more seven experience than me.
As for the mixture, what colour are the spark plugs after a good run?
