[Julia]

Car carburetors do need cleaning. Below is an introduction to relevant information: 1. Function: The carburetor's role is to utilize the kinetic energy of the incoming air stream to atomize gasoline. 2. Carburetor: The carburetor automatically adjusts the mixture ratio according to the engine's different operational states, delivering the corresponding concentration and quantity of the air-fuel mixture. To ensure the mixture is uniformly blended, the carburetor also has the effect of atomizing the fuel for proper machine operation. Below are extended details on carburetor mixture ratio adjustment methods: 1. Air intake obstruction: First, check the tightness of connections related to the carburetor to ensure normal air intake without leaks or obstructions. 2. Fuel mixture: Turn the carburetor mixture screw clockwise until it stops, then turn it counterclockwise 1.5 turns. Start the engine and let it warm up for 10 minutes to reach normal operating temperature. Adjust the carburetor's idle speed screw to set the engine at the lowest possible speed without stalling. 3. Engine speed: Repeatedly adjust the carburetor mixture screw left and right to achieve the highest engine speed.
