SX throttle cable a bit sticky
Discussion
Could also be a bit of fraying (happend to my throttle cable) and wrecked the full cable. Worth checking for this as in the end mine snapped being into 2 weeks of wedge ownership!
Outer was ok, and replaced with a push bike cable as original replacement was expensive for what it was. After 7 years the cable is still fine, and carry a spare in the boot.

Ahh - I think I see the problem now:
As you can see, only one bit of the wire was holding the nipple on! Plus all the fraying was stopping the cable getting back in the 'ole.
After a bit or re-plaiting the cable - luckily it all went back together perfectly - and soldered the nipple back on, almost all was well:
however the cable didn't like the silicone oil I had sprayed down the middle and was sticking really badly, so badly in fact that I though it was frayed in the middle too. So I took it all apart, it was fine, so I put Moly grease all over the inner and put it back together. This time it worked perfectly. It mut be that the silicone oil was too thin.
THe cause of the original end snapping off after a mere 26,000 miles seems to be sloppy engineering - no wonder TVR's got a bit of a bad rep for being unreliable. Firstly the end of the accellerator lever with the cable in wasn't very well aligned with the cable end in the bulkhead, causing it to pull to one side, and secondly the lever was really sharp at the back end - cutting into the cable. So I bent the lever slightly and deburred the hole that it engages in, should last much longer this time. If only they spent 10 minutes in the factory on a little quality.

I'm not sure that solder is a good long term solution though. Proper crimping or silver solder would be better IMHO.
Just a thought... If the cable didn't run smooth with silicone oil could the outer be damaged?
Also make sure the return spring/s is/are 100% operational just in case you loose your nipple(s) again (pun intended).

Interesting about the dodgy engineering.
My bugbear in the 280 is the truly TERRIBLE design bodge they did on the cable clutch, made EVEN WORSE by poor finishing and quality control.
This pushes the outer of the cable, but also has a big bend on the inner, and [original setup] rubs against inner, making it's life very short.
Quick fix takes about 20 minutes in total in your garage, with a bit of cutting and filing. TVR could have done this in 2 minutes whilst building it in the first place. It's just sloppy.
I've managed to improve mine, and it already makes quite a difference, but to do it properly either requires a setup like the 'M' series, or change it to hydraulic like the 'S'.

Hi Andy...The 280i clutch cable was something i used to dread...Without the mod that you suggested it would snap every year without fail so i always carried a spare and a tin to drain off the oil from the filter as that needs to come out to get to the adjuster...ARPITA.....Chhers...Ziga
With a but of imagination I managed to fit the new TVR parts accelerator cable. Works great!
