Carburetor — Maintenance (Peugeot 305)

1. Keep in mind that the carburetor itself rarely needs adjustment, and the need for it usually arises when, by changing the parameters of the carburetor, they are trying to compensate for the drop in the efficiency of the old engine. In countries where emission levels are regulated by law, carburetor adjustment should be done in parallel with emission control (using special equipment).

2. The main cause of carburetor problems is wear on moving parts or clogged jets. The Solex carburetor has no constantly moving parts except for the float and throttle shaft, making it extremely reliable (unless it gets dirty). If from time to time to lubricate the carburetor linkages and the throttle shaft with engine oil, the carburetor can last for years and its bulkhead will be required no earlier than the bulkhead of the entire engine.

3. The current maintenance of the carburetor consists only in periodic cleaning of the float chamber and jets and inspecting the strainers located at the carburetor inlet and the accelerator pump inlet. All these operations can be performed without removing the carburetor from the engine.

4. Before disconnecting the upper part of the carburetor from the lower one, it is necessary to clean it well from the outside with kerosene or branded cleaner and a stiff brush, and then wipe it dry with a clean cloth. All this is necessary in order not to bring dirt into the carburetor.

5. Remove jets, wash them in clean gasoline and blow with compressed air. It is forbidden to clean the jets with wire, because. this may throw off their calibration.

6. Pull out the float shaft and remove the float. Unscrew the needle valve and wash it in gasoline. Remove sediment from the float chamber by flushing it with gasoline (do not wipe the camera with rags). The mesh filters at the carburetor inlet and the accelerator pump inlet must be washed with clean gasoline and dried with compressed air (it is forbidden to wipe them with rags). After installing the float, check and, if necessary, adjust the upper position of the float (see section 8). Check the stroke of the accelerator pump and adjust it if necessary (see section 9).
