(1) it may be that the oil in the oil tank has not been drained for the first year, so check whether the fuel is qualified fresh oil.
(2) its function is to send the pulse high-voltage electric discharge of the high-voltage conductor (the nozzle line), break through the air between the spark plug and the two electrodes, and generate electric spark to ignite the mixed gas in the cylinder.
Many idling unstable, jitter, poor acceleration, lack of power, frequent idling self-extinguishing phenomenon, oil and gas consumption increased.
This is due to damage to the spark plug.
If the spark plug dirty, can clean, serious damage, need to replace the same model accessories.
If ignition is not possible, the gap between spark plug electrodes can be adjusted, with 0.6-0.9mm in winter and 0.9-1.0mm in other seasons.
