Why does Haojue Yue Xing strike a light to cover the carburetor?

Fuel injection is too thin. Carburetor is a mechanical device that mixes a certain proportion of gasoline with air under the vacuum generated by engine work. Haojue Yuehang's fuel injection is too thin and easy to catch fire. Cover the carburetor when you need to catch fire. Carburetors can be divided into simple carburetors and complex carburetors. Carburetors can also be divided into downward suction type and horizontal suction type. According to the type of throttle valve, carburetor can also be divided into rotary type and lifting type. The rotary throttle valve is a disc-shaped throttle valve, which rotates around the axis between the throat of the carburetor and the intake pipe to change the flow area of the intake passage.
