Unstable idle speed as follows: idling, launched shaking speed is not an average. The reason: the idle air jet infarction, idle poor installation work, the individual cylinder spark plug spark is too weak, individual valve Mifengbuyan, intake manifold leak, too early or too late ignition timing, idle speed and adjust properly.

Launched the machine unstable idle, you should first adjust the idle speed, such as idle speed adjustment problems still can not eliminate, you should check the pilot jet and idle air jet Can infarction, infarct, such as the amount of holes available gasoline or acetone cleaning and tightening of the air blowing pass; such as the amount of holes not infarction, should be initiated by machine speed stabilized at a certain speed, the police listen to the intake manifold or carburetor in the lower part of the liner, whether the leak, such as rendering the leakage phenomenon, the available fastening screws or additions to, minus the gasket way to wipe out. Such as unstable idle while accompanied by the phenomenon of initiated the machine power landing, you should check the spark plugs working conditions, whether the proper valve sealing performance and ignition time if necessary to stop the overhaul, adjust.
