The least disturbance in the balance of the air and petrol combination made by the carburettor thus leads to its malfunction, and interferes, in a more or less significant manner, in the proper working of the engine which generally leads to the need of sometimes replacing this part or the elements constituting it. How to select your model? Nothing resembles a 2 CV carburettor more than another 2 CV carburettor but different models have however been fitted in the legendary Citroën in the course of its history. The 2CV type A of 1949 and then the 2CV AU received an inverted body single carbu provided by Solex and named 22 ZACI. The 2 CV AZ and AZU are sold equipped with a 425 cm3 engine since 1954. Then emerged a new model, the Solex 26 BCI that greatly evolved in October 1955 and April 1958 to also be fitted in the 2CV AZL and AZLP. Then came the 26 IBC carbu in the 2CV engines whose engine size was now 425cm3, carburettor whose nozzles would widen with time as the power increased, going from 15.5 mm to 17 mm and then 19 mm. February 1963 saw a new 425 cm3 engine on the 2 CV sedan (AZL and AZLP). It received new cylinder heads and a new 18ch nozzle with a Solex 28 CBI carburettor if the clutch was centrifugal and Solex 28 IBC if it was mechanical. The AZAM model would be either fitted with this reference or with the Zenith 28 IN reference, first 2CV carburettor not belonging to the Solex brand from the creation of the legendary Citroën. When the first light van came out in 1963, it was fitted with a 602 cm3 engine and a Solex 30 PICS. In 1967, the 2CV AZU switched to the 32 PICS carburettor. Then came various models in the 2CV 4 and 6 depending on the presence of a mechanical clutch (Solex 34 PICS 4, 34 PICS 5, 34 PICS 6, 34 PICS 10) or a centrifugal clutch (34 PCIS 4, 34 PCIS 6, 34 PCIS 10). There was a change of course in July 1978 with the switch from single-body carburettor to double-body. Named 34 PICS 10 (mechanical clutch) and 34 PCIS 10 (centrifugal clutch), this 2CV carburettor had an idle adjusting screw that was not accessible without destroying its plastic cap that prohibited the access to the same. Finally, in July 1978, the 2 CV 6 adopted a double body Solex, i.e. the 26/35 CSIC (mechanical clutch) and the 26/35 SCIC (centrifugal clutch). With the centrifugal clutch being definitively removed in July 1983, only Solex 26/35 CSIC was fitted in the 2 CV 6 till the end of its production. Our company sells a certain number of these models among which the single body ones are 28CBI, 28BCI or the 34 PICS 6. There also are the renovated Solex 26/35 CSIC 2CV carburettors or the double body 2CV carburettors from its production. What is the difference between a single body and a double body? The “single body” carburettors take in air in the air filter and spray the petrol in a single chamber before letting the mixture go to the pistons. The “double body” carburettors have two chambers where the air/fuel mixture can be made. The beginning of the stroke of the accelerator pedal uses the first chamber; the carburettor then acts as a single body.
If we continue to accelerate, the mixture will then be made in addition in the second chamber thus enabling an increase in power as well as increasing the consumption.
Our catalogue also includes numerous accessories of the 2CV carburettor: throttle cables, centering punches, membranes, fastenings, jets, gaskets, floats, struts. Go for the MEHARI CLUB CASSIS, an expert for 30 years, for the carburation of your 2 CV.
