The adjustment and repair methods of motorcycle carburetor are as follows:

1. Open the valve cover of the motorcycle carburetor and turn the burning timing "t" upward;

2. Adjust the valve screws to reserve the expansion interval;

3. Cover the valve cover and start the engine for heating for 3 minutes;

4. Screw the motorcycle screw and the broken saw blade together, and turn to the high speed direction of the engine. After turning to the speed, reduce the idle speed and repeat this action until the engine runs smoothly.

The carburetor is a relatively fine motorcycle part. It can mix gasoline and air in proportion, and then use the kinetic energy of the intake air flow to complete the atomization of gasoline. The carburetor is actually a pipe with an adjustable plate in the middle, called the saving plate, to control the air flow through the pipe. The tube has a shortened part called Venturi tube, where a vacuum is formed. The shortened part has a metering hole through which fuel can be sucked in vacuum.

Motorcycle carburetors look very messy, but in fact, as long as we grasp some principles, we can adjust the motorcycle to a good state. All carburetors work under the basic principle of atmospheric pressure. When the piston moves to TDC, the spark plug burns accurately to complete the gasoline burning and work. The color of the center electrode of the spark plug can roughly distinguish whether the carburetor is too thin or too viscous.

Under normal conditions, the center of electrode shall be brick red. If the spark plug is white, it indicates that the mixture is thin; If it is black, it means the mixture is thick.
