Carburetor engines
Attention! The mixture adjustment screw is covered with a plug, which should only be broken off in the event of carburetor repair.
1. Remove the carburetor. The mixture adjustment screw is located at the base of the carburetor, next to the crankcase ventilation hose. Install the carburetor with the base facing up.
2. Drill a 2mm diameter hole in the carburetor base boss. This hole should go under the plug and intersect the internal well of the screw.
Ream the hole with a 3.2mm drill.
3. Use a punch to knock out the plug. Install the carburetor, connecting all hoses.
4. Start the engine and warm it up at idle speed. Turn off all on-board consumers. Place the transmission in neutral. Turn off the ignition, disconnect the battery from ground for 5 seconds. Disconnect the oxygen sensor wire.
5. Increase the speed to 2000–3000 rpm, after 5 seconds switch the engine to idle for 2 minutes.
6. Connect the tachometer. With the engine idling, check the CO content with an analyzer, it should be 0.1-0.3%. Adjust if necessary by turning the screw. If the speed changes by 100 rpm during adjustment, then adjust the speed and mixture composition so that both indicators correspond to the norm. Stop the engine, connect the oxygen sensor wire and install the plug.
