Is it difficult for Lingjun to start at Chai during the National Five-Year Plan?

It is difficult to start the engine if the starting time exceeds 30 seconds each time or the starting lever is continuously pressed for more than 10 times. This kind of fault should be eliminated in time, otherwise it will lead to the damage of other components. It is difficult to start the engine, which is usually divided into the following two categories: 1, and the starting method is incorrect, such as the choke valve is not closed when the cold car is started, or the float sinker is not pressed, so that the combustible mixture entering the cylinder is too thin; When the heat engine is started, the choke valve is closed, or the float sinker is pressed for many times, so that the combustible mixture entering the cylinder is too rich, and the spark plug is "submerged", resulting in that the engine cannot be started. At this time, the choke valve and pressure reducing valve should be opened, or the spark plug should be removed, the engine should be rotated, and the fuel in the cylinder should be drained before restarting. 2. If the starting method is correct, but it still cannot be started smoothly, there are usually the following reasons: (1) The fuel mixing ratio is wrong; (2) The combustible mixture is too thick; (3) The spark plug has no fire or weak fire; (4) The battery power is insufficient; (5) The ignition time is wrong; (6) Insufficient cylinder compression pressure; (7) Excessive carbon deposition or blockage in the exhaust port and muffler. If the engine is difficult to start, it can be checked and eliminated in the following order: 1. Press the horn once and judge whether the battery is full according to the sound of the horn. If it is not enough, check whether the electrolyte is sufficient and whether the battery case and plate are damaged. 2, check the spark plug, according to the spark intensity of the spark plug, judge whether the ignition system failure or oil supply system failure. Ignition system failure or oil supply system failure. The faults of ignition system generally include: dirty spark plug, broken high-voltage line, damaged capacitor, diode and transistor circuit, ignition switch and main switch not turned on or off, wrong gap of breakpoint contact or unequal surface. 3. Remove the spark plug, turn the engine, and judge whether it is an oil supply system problem or an ignition time problem according to the dryness and smell of the exhaust gas. If the spark plug is dry, the smell emitted from the spark plug by the rotating engine is dry and tasteless, indicating that the mixture has not entered the cylinder. Check whether the fuel tank switch, oil circuit and carburetor are blocked. If the gas discharged from the spark plug hole smells of gasoline and there is no obvious oil bead discharged when the white paper is near the spark plug screw hole, it is that the mixture is too thin. If the spark plug is wet, the mixture is too rich. 4. Remove the magneto cover and check the ignition time. If the ignition time is wrong, adjust the circuit breaker. If the ignition time is correct, clean the circuit breaker. 5. Install the cylinder pressure gauge for inspection. If the compression pressure is not less than 6. 10 Pascal, it is an internal mechanical failure of the engine, such as the gasket at the joint between the cylinder and the crankcase is damaged, the crankcase oil seal leaks, or the fastening bolt is loose. If the compression pressure is greater than 6. 10 Pascal, check whether the exhaust system is blocked. When there is no cylinder pressure gauge, you can remove the spark plug, plug the spark plug hole with your fingers, and then turn the engine. If your fingers feel a violent impact and the cylinder makes a "poop-poop" sound, it means that the compression pressure is high and the crankcase is well sealed. If the fingers can't feel the impact, the engine is difficult to turn, which means that the crankcase leaks or the piston ring and the cylinder leak together. 6. Remove the muffler. If there is too much carbon deposit, the exhaust system will be blocked.
