【When should I replace it?】
Problems with the generator "stuttering" and not firing properly. An intermittent or continuous shuddering of the engine with an abnormal "clunking" sound indicates a possible problem with one of the spark plugs. If the color of the spark plug is stained oil, it indicates that the spark plug gap is out of adjustment or too much oil supply, and the high pressure wire is short-circuited or disconnected. If it is smoky black, indicating that the spark plug hot and cold type selection error or thick mixture, oil upward. If the spark plug is seriously eroded, the top of the scar, black lines, rupture, electrode melting and other phenomena, which indicates that the spark plug has been damaged, must be replaced immediately.
