Somehow when getting out of the car in a confined space (my garage) I managed to get my right foot somewhat stuck and dislodged the throttle cable at the pedal end. Bcensoreder!

By wedging the throttle open at the engine end, removing the steering wheel, and contorting my ageing frame into the footwell, I had enough slack to get the cable back in place. Surely this must be the worst god-awful bit of design ever? I’ve checked in The Bible and searched on PH, but most threads deal with snapped cables.

I'm a worse artist than I am mechanic, so on my "exploded" drawing am I missing something that should sort of pop over the top of the pedal end cutout, to stop the cable just pinging out?

Thanks chaps for your replies. So I’ll work on the basis that the pedal end is OK. But that raises a slight issue as to the other end. As assembled (before I started taking stuff apart), there was an apparently random bolt with locknuts that was just screwed all the way down, so it did nothing. I have reassembled it on the basis it’s some kind of limit stop to make sure the throttle can’t be opened up to the point where the engine thrashes itself to pieces? But since I don’t know what it’s called, I don’t know what to Google. That would also mean the throttle cable could in the extreme case of heavy-foot-itis be put under massive tension and lead to it snapping? Or is my reasoning completely rubbish, and as they used to say of my school homework about 60 years ago, “See me”…..

Thanks all for the very helpful suggestions. It's all back together again, and I'm sure the neighbours will thank me for not starting her up until the morning.

It's still a pretty horrifying thought that (just like those 4 little envelope-sized patches of rubber that keep us glued to the road), it's a rubbishy old bit of cable that transfers the thoughts from our brain, through our right foot, and to the engine.

Mind you I wouldn't fancy trying to fix any of the above on a rainy winter's night somewhere in the countryside -- don't smirk, in the (rather distant) past I have used TVR's as my daily drive.smile

Mine had evidently been dismantled in the past and tinkered with, and there's no sign of that drilled bolt (which would be my expected way to make the connection). Good point about the pivot point, "mechanical advantage" and all that O-Level stuff. I recently refurbed some cleverly-designed folding garden chairs for my daughter, and just like TVR's, there seemed to be at least a dozen ways to put them back together, but just like TVR's only one of them was correct !
