Throttle stuck open

I think this is probably the best place to add this note as it appears to be a tech issue.
During the strip down of my Roadster, following my off at Snetterton, I have idendified the true cause of my stuck throttle.
I wanted to test my original theory that my extinguisher cables caught in the throttle return spring but found that I couldn't hold the throttle return gubbins open this way. I then pushed the accelerator peddle flat to the bulkhead, to see if the mechanism was faulty in some way, and the peddle failed to return - throttle almost wide open!
A closer look revealed that the linkage on the back of the peddle assembly, which holds the cable, had caught on the edge of the cable access hole in the bulkhead. Also, the cable itself was fraying badly where it has been rubbing against the edge of this access hole and is about to give out completely (shame it didn't do that first!).
I suggest, as a matter of urgency, everybody checks this aspect of the peddle assembly.
Anyway, back to the garage....
