Citroen DS wouldn’t idle

admin — Sat, 27 Dec 2014 12:08:41 +0000

I came to start the DS the other day, and it started fine, but would not idle properly. Once the revs dropped below 1200 or so the engine died. The car had been running fine before so it was quite perplexing. I had some advice from the forum to try a few things, one was to check the float in the carburettor which was fine, and the other was to check the idle jet. I wasn’t sure which was the idle jet and I didn’t want to mess with the settings, so when Jason who looks after the car for me offered to come over and show me, I was very happy to take him up on that.

Turns out it was the problem and I didn’t even need to take the top of the carby, the idle jets can be removed and cleaned from the sides. One of the two jets can be seen on the side of the carby in the picture.

After suffering the humiliation of a ham fisted owner the DS is back on the road thanks to Jason Hantos. It’s also all ready for another year of rego, success! Quite a hassle to have it towed

The DS is going to need a tow

But at least it won’t get dust in the gear selector.

I obviously stuffed up in my repair of the carby fuel inlet as I noticed fuel leaking from there, and in trying to tighten it a little, broke it off. It’s a good lesson as amateurs will make mistakes from time to time and they can cost money.

Broken Carby – stuffup

As luck would have it, the car is already booked into the shop for later this week for its rego, it just won’t get there under its own power.

Given the car won’t run, I took the time to finally get the gear mechanism rubber to fit properly. This was quite time consuming and it needed soap and water to finally get it on.

Preventing a DS Flambé

While the Citroen DS can be a rather hot car due to the engine being right next to the drivers knee, it is generally not a good idea to let it get even hotter through an engine fire. The weber carburettor that is used on the DS has the fuel inlet fitting press fit into the top housing of the carby, which as these cars age means that it can work its way out and have fuel spraying all over the hot engine. Not a great idea.

However, on a recent thread on the AussieFrogs forum, a well respected member had made up some kits to reduce this risk by tapping a thread into the carby, to allow the inlet to be screwed in. I was able to grab one from the last batch and I fitted it today.

Luckily, my car wasn’t as much of a driving time bomb as some, as I needed to use penetrating fluid to get out the old inlet, but I’m still glad I made this change, as this new fitting is not going anywhere! I removed the top of the carby to use the tap, which made it much easier, and found a dentists tool was a good way of making sure the threads were clean before I screwed in the new fitting. (using grease on the tap got most of it). There is also a small filter in the carby which I cleaned at the time.
