Hi Darren . Before you go and buy a cable , check the pedal bracket . It's a bit of a back breaking , neck twisting job to remove it but , you may find the problem lies in where the pedal pivots through two plastic bushes . I had this very issue with my accelerator , as did another forum member . He did a very good " How to " but I'm buggered if I can find it now . Anyway, just check out where the pedal pivots before buying a cable .
