Description: Rough starting behavior of the engine can be the result of an incorrect idle mixture. This can be adjusted using regulating screws, which should be replaced if wear occurs. Here you will receive a new idle adjustment screw with the associated compression spring for a Solex carburettor type 40 PII-4. There are two of these screws per carburettor so that the fuel-air mixture can be specified for the respective cylinder when idling. As a result, the idle speed of the engine can be adjusted. You can also find other carburettor components in our shop.
