1) Theory guides practice. It is necessary to fully grasp the basic principles and basic structure of small gasoline engines to be able to analyze and deal with faults, especially for specific models of different types of diesel engines;
2) When a fault occurs, a comprehensive and scientific analysis and judgment must be carried out on the spot to ensure that the fault is handled accurately, and the problem cannot be handled based on imagination or the so-called past experience. Gasoline engines often have oil circuits, circuits, and other parts that fail at the same time, resulting in more complicated failure phenomena. Sometimes different failure points will have similar phenomena, which will cause certain difficulties in troubleshooting. Through the analysis and thinking of the failure phenomena observed on the spot, the various possible causes of the failure can be conceived and analyzed and compared, and the scope and location of the failure can be determined. Then from simple to complex, from the outside to the inside, first analyze the circuit and then the oil circuit, then adjust the ignition time, check the order of the gas timing, and compress the fault to a certain point;
3) Develop good habits, do the necessary inspections before starting up, and make regular inspections during the operation of the machine to avoid sudden failures as much as possible;
4) Strictly carry out technical maintenance at all levels of the oil machine at ordinary times to ensure that the oil machine is in good working condition and avoid sudden failures and major accidents.
