Attention. If the engine runs unintentionally after switching off the ignition, although the carburetor and ignition are set correctly, a solenoid shut-off valve can be installed instead of the screw plug -Q-. Electrical connections: Disconnect the plug of the positive connector of the ignition coil (terminal 15) and connect with the connecting wire of the solenoid shutoff valve. Connect the second plug of the connecting wire to the ignition coil. Turn the ignition key to position II and check if the (clicks) valve. Check CO content and idle speed.
