What are the reasons why the Jade one-button start fails to ignite?

[MaddoxAnn]

The main reasons for the failure to ignite lie in the engine's oil circuit, electrical circuit, and mechanical faults. The following are the specific reasons why the Jade fails to ignite: Oil circuit and electrical circuit aspects: From the oil circuit perspective, the main fault is low gasoline pressure and poor atomization; from the electrical circuit perspective, it is due to excessive spark plug electrode gap, decreased ignition coil energy, and short circuit or open circuit in the cylinder line. Excessive carbon deposits and dirt: Excessive carbon deposits and dirt in the intake tract change the cross-sectional area of the air passage, making it impossible for the control unit to precisely control the idle intake volume, resulting in an overly rich or lean mixture, causing abnormal combustion or engine shaking after starting, or even failure to start.
