A rare and vicious Citroлn disorder carburettor 2CV.
very unstable at low engine speed, when the acelerator pedal is slightly down.
perfect high speed operation of state engine when the accelerator pedal is quite low.
And some random stroke engine is back to perfectly normal idle OK, OK at low speed until everything goes wrong again.
It looks like a dirty idling jet but if you check the jet, his own and if you open the carb there's nothing wrong.
It took me a while to see where the problem was that he was here.
First we will see how the carburetor in this area when there is no problem, it will allow us to understand the problem and fix it.
On a single barrel the problem studied here can not happen, so if you plan to change a single barrel for a double, don t First, the throttle control does not work the same way while pushing, Barel on the single; pulling the double barrel, so you'd have to do more work on the pedal; Second, you add a condition to your potential 2CV, which is a good idea and finally, the extra power from the double barrel is not so much and not worth the trouble of changing.
Basically, a double barrel carburetor has two carburetors in one, you can see clearly if you look at the entries Carburetor or you see the two inputs and outputs outputs here, the first barrel, the smallest, is left.
The first barrel works to a certain power, and the second barrel works to go over the power that can be delivered by the first only they do not work exactly that way, in fact, the second barrel starts to act before the first is at its maximum power when the engine is cold, the choke closing the first body to the second is already closed the first is not opened by the accelerator air and gasoline engine goes through bypass holes is how it works on the carburator 2CV a traction rigid cable for closing and opening to push.
The problem studied is not of the throttle system.
The position of the accelerator Note that the spiral spring by a hook.
Control of the second cylinder closed Note the hook.
first barrel barrel almost entirely starting to open second opening.
Control of the second cylinder fully opening the second cylinder.
The spiral hook is used to close the second body, it acts only when the throttle is released Suppose now that the spiral spring is broken, what will happen the hook will no longer act and we therefore have that.
Trouble second barrel remain fully open regardless of the position of the first barrel.
No more idle, the engine is stopped, because there is too much fuel and air from the second barrel.
very unstable at low engine speed when the accelerator pedal is slightly down because there is too much gasoline and air from the second barrel.
perfect high speed motor operating status when the acelerator pedal is quite low because the second body must be open and open, it affects his usual way.
And some random stroke engine is back to normal perfectly OK to idle at low speed OK until everything goes wrong again because there is the friction and inertia of the parts mainly if some soil around quite some time to move all the parts and close the second cylinder when all sudden release accelerator.
If you can remove the carburetor, its not too difficult to fix the spiral spring with a strong, thin grip, but if you like mechanical challenge 2CV guilty, your honor you can fix it with the carburetor on the 2CV I spent several hours on it and then use the other spring than had done the hook, this additional spring has not acted on anything carburetor used for images also that the additional spring does not act on what whether what was the original work of this mystery spring.
The following people have nothing to do with the previous one, but as I had the carburetor on his stand and the camera is ready, I took the picture Sometimes, depending on the thickness of your key, you might have hard to unscrew the idle jet one solution is to cut a portion of the carburetor, under the entry of gasoline in the tube, there is a lot of empty space, the more metal carb is quite mild and you can cut easily with a small piece of metal saw blade cutting off the metal is presented as yellow on the images below.

Your advice on problems in slow motion in the 2CV is linked to dirty sources was extremely helpful I drove for 3 days long Taos in New Mexico in Louisville, Kentucky having to pump gas until it got up to speed coming all the way, he refused to go until I fixed worked for two days until I your site and was immediately set again, many think for sharing your gratious your time and knowledge Best wishes, Jim.
