Key hints: the cause analysis and treatment measures of the unstable engine work: the reason: the sequence insertion error of the high pressure line of the cylinder, the phenomenon: it is very difficult to start, the serious instability after starting, accompanied by the backfire and the sound of the exhaust pipe, and the measures are to rearrange the high pressure line of the cylinder in the order of ignition.
Reason: the sequence of the high pressure line of the cylinder is inserted in the wrong order. It is very difficult to start. It is seriously unstable after starting. It is accompanied by the echo and the sound of the exhaust pipe. The measures are to insert the high pressure line of the cylinder again according to the order of ignition.
Reason: the contact gap between the broken electrical apparatus is too large, the phenomenon is unstable, there is a lack of fire stop phenomenon, the more the speed is more serious with the exhaust gun sound, the measures: the contact clearance is adjusted to 0.35~0.45mm reason: the gap of the broken electrical contact is too small, the phenomenon is that there is a fire stop sound, the high speed is also not improved, the ignition coil is easy to heat, and the ignition coil is prone to fever, measures Shi: the same measure.
Cause: spark plug charcoal, phenomenon: in all circumstances, there is a fire phenomenon, only after the big coax oil or high speed exercise for a period of time after a significant improvement, measures: remove the spark plug clearance of carbon or the heat type spark plug.
Reason: the fire head leakage, phenomenon: starting difficult, starting after the operation is unstable, the sound discontinuous and exhaust emission phenomenon, do the cylinder high pressure line jump fire inspection of all cylinders have broken fire phenomenon, measures: check the fire head leakage, replace the fire head.
Reason: voltage cover leakage, phenomenon: Engine instability, fire and temper phenomenon, can see the distributor cover "creeping" phenomenon, measures: replace the new distributor cap.
