The Engine Is Flooded With Too Much Fuel, And The Starting Is Poor

The common failure of excessive fuel in vehicle starting, that is, a large amount of fuel is sucked into the engine cylinder and then loses the ability to start, commonly known as the "drowning" phenomenon. Especially in low temperature in winter, when the engine is started for the first time, it is often willing to calibrate more fuel to increase the amount of gasoline in the cylinder, so that the car can be started at low temperature. However, when the amount of gasoline in the cylinder is too much, the normal combustion and explosion of the spark plug is blocked, resulting in failure to start or knocking on the cylinder. It is the so-called "flooded tank". The solution is to remove the spark plug and clean it up. If there is too much oil in the cylinder, suck it out.
When there is too much fuel, the ignition system works normally, and the oil supply system does not fail to supply oil. When the starter is used to drive the engine to run, it cannot be started, or there are occasional symptoms. Sudden, sudden" sound, even "blasting" phenomenon, and there is a pungent smell of raw oil. Observe the appearance of the carburetor. Gasoline flows out continuously along the throttle shaft, and oil leaks from the liner of the float chamber. Remove the spark plug and you can see that there is wet gasoline around the electrode; there is carbon deposit in the combustion chamber. This kind of phenomenon is that there is too much fuel and the mixture is too rich.
