I'm a bit stumped. My throttle cable sleeve broke in the middle, causing the cable to catch sometimes, and jam the throttle on, and never returns to idle properly. I have made a temp splint, to tie me over, but need a new one. So, I ordered one of ebay. Add said fits all Australian minis, and the photo looked like the one I have.

It turned up, and the black sleeve tube is onle about 40cm long! This won't reach from the firewall to the carb at all, let alone in a nice arc so it operates nicely. The old one was at least a meter long. It comes straight out of the fire wall, loops past the brake booster, almost touches the grill, then over the engine and into the carb end holder thingy.

Where is the best place to get one? I'm in Sydney.

Go to a deadly treadly bicycle shop of some repute and ask for a brake cable (not to be confused with gear changer cable, this is smaller in diameter). Bike brake cables are heavy duty and are of better construction than the POS Chinese cables, especially is name brand like Shimano or recommended by the shop. They will have self lubricating Teflon lined outers, and the inner cable will not rust unlike the shitty cables from the parts shops and is the same strength at a minimum, but almost certainly better.
They will also have the lead block end identical to the one on your current cable fitted to your car for the peddle end. All you need to do is cut the outer to length and then the inner once you have it all fitted to the carb.

The red hot part is that you won't pay more than 10 bucks for a meter of the stuff.

Pull the brass ends off the old cable you have, these will come straight across onto the new one.

What a fantastic idea.

From bmx experience odyssey linear cables are the go. Extremely long lasting, and super smooth.
Plus come in heaps of colours to match your engine bays.
Normally 15$.

I have been using bicycle brake cables for accelerator cables in Minis for years. They are good and cheap and at four bucks a pop you can afford to keep a spare one under the Mat like I do. They also come in different colours even Pink if you need one ! I usually cut them to the length I want and tin the end of the inner cable with a bit of solder so it stays together and does not fray when you feed it through the anchor bolt on the carby.

They should also be able to give you the little metal cap to keep the end of the shroud from getting munted where it rests against the carb bracket. Basically a cylinder closed at one end with a hole in the end for the wire.

Thanks heaps guys. Will head to a bike shop this weekend.

When fitting a new cable make sure that the pedal is on the floor at 99% throttle opening and not 101%.

Or in other words make sure the cable is not being stretched when the foot is flat.

If you make it to tight it will break very quickly.
If you make it too loose you will not get full throttle.
Only one of these two options will leave you stuck on the side of the road.

The good Shimano ones (and the even better ones are stainless) come with the end already soldered, so you just fed 'em through then cut the excess off once you're done.

Fitted the new cable today. Cost $10 from my local cycle shop. It was a perfect fit. I didn't realize how buggered the old one was. The throttle response is way better now.

Thanks again for the tip guys.
