Causes of engine failure and cut off work

There are a number of reasons that lead to engine failure, the most important of which are:
First: When an inappropriate quality of spark plugs is used, especially non-original ones, and often causes interruptions in the engine’s work, for example, the spark plug cable should be checked, as well as the generator or charger. 

Second: The presence of dirt or blockages in the fuel corridors and a weakness in the fuel pump, as well as problems in the feeder due to dirt, whether it is in the carburetor or atomizers.
The rotating engine is mostly caused by the fuel system or the ignition system.
