Solex 34CIC

Here is some collected information about the Solex 34CIC carburettor in the Matra Murena 2.2. Unlike what some people tend to think, I find that the Solex 34CIC is well worth maintaining. Some choose to substitute with a Weber, and while I don't doubt that the quality of the Weber carburettors is generally better than the Solex's, the 34CIC is not bad at all and works very well, even on my Holbay Fast Road Cam, which is even a bit more aggressive than the standard S-cam.

On the pages below, I've described what I know about the 34CIC in order to help others.
