Note. Carburetor screws, with which the composition of exhaust gases can be changed, must be protected by seals by law. If the carburetor has seals, they can be removed with pliers or a screwdriver. It is advisable to screw a suitable screw into the seal and remove it together with the seal. In this case, they are destroyed. After adjustment, the screws must be protected with new seals.
Caution! When working on the carburetor and fuel supply system, certain cleanliness rules must be observed, see Chapter Power supply system, carburetor, fuel injection system, Chapter Cleanliness rules when working with the power supply system.
