Way back when I bought my 2.2 the car came with a new carburator from a Citroen CX 2400.
It was sold by the Matra dealers as a original replacement.
I never liked it.
I laways had to drive the car with a bit choke and acceleration was way off  specs and with hiccups.

A while ago I found a used carb for the Murena.


This is the Talbot carb.


Ordered a kit.
This is a kit for the CX.
Most things can be used except top cover gasket.
It looks different and I didn't want the gasket to mess up so I ordered a seperate one.



The small o-ring for sealing the acceleration channel is not included.
I found that size OD 6mm; Thick 2mm (tight fit);  or OD 5mm;  thick 2mm; do the trick.


Axles in good shape so I cleaned it and placed the kit.
Note...This membrane needs the little rod from the old carb mounted.
I punched it in.





I heared that solexes are sometimes bend.


I conroled it and  found 0.15 mm.


Flatten it .



Floater tested in hot water.


Finding info about this Solex is difficult.
Nowhere is described how to adjust float hight.
Pictures found tell me it has to lay parallel with top and then has to shut off the needle.


I locked the floater with some paper. in a parallel line with the top.




measured the float stop cut off from the top.


And the float lift point with gasket on.


Brought the 2 parts together en tested leaking.

Aceleration jet had a lot of play,somebody tought it was adjustable and damaged the house there.

Solved with a o-ring.


Mixture screw new rubber. and sit tight.



ready for some action.


Mounted the thing in the car and after some fidling with idle. mixture screw and float height (2mm lower) the car runned like never before.

It is clear to me that the original carb is best thing.
The Citroen carb is way of specs and a bad replacement.
Here the specs from Tabot and Citroen carb.

Aux;;4.0,  Venturis ,25 primair 26, secondair
Air correctiion 190 primair 180 secondair Lower jets: 127.5 primair 135 secondair.

34 CICF 161.
Auxi; 3.0  24 primary 27 secondary.
Air correction 180 primair 200 secondair. Lower jets: 130 primair 122.5 secondair.

Hiere a picture where they placed.

That's great - thanks for sharing, and congratulations on your new original carburettor Smiley

Yes, and it should never have been sold for the Murena 2.2 as it is completely the wrong specification!  It shows how these people selling alternative carburettors really don't have a clue or understand carburettors.  The carb. on the CX2400 is the 34 CICF 161 as you point out Herman whilst the carb. on a Murena is the 34 CICF 141.  The venturis are cast in and are different for a start, and much of the other jetting is different too.

One mistake though is you have put '25' and '26' on the Auxiliary venturis which is incorrect.  The Venturis are below the Axuiliaries and are cast in with the body.  The Auxiliaries are removable.  '4' and '7' at the top of the emulsion tubes are the air correction jets (190 and 180).

This information has been on my website (in the FAQ section) for any owner to find, for many years.

Yes the drawing I made is not logical.
The auxi are both the same I measured.
The lower part I measured 25  and 26.
I will try to  find a better picture an put the numbers  on the right place.

Found a drawing that is more like the CIC.
I filled in some info.
For some reason I couldn't change te drawing anymore so I put it here.
If something is not right just tell me.
