Instruction. According to the established rules, the exhaust gas composition adjustment screws must be closed (sealed) to prevent self-adjustment. The location and number of screws depend on the type of carburetor.
The seals on the adjusting screws can be removed with pliers or a screwdriver. In some cases, you can use the following method of removing seals. A screw with a diameter of 2 mm is screwed into the plastic seal and it is pulled out together with the screw. After appropriate adjustment, the screw must be sealed with a new seal, available in the spare parts kit. Until those mountains, until the composition of the exhaust gases meets the established standards, the operation of the car is not allowed.
