MAINTENANCE Spark plug The spark plug condition is influenced by: S Incorrect carburetor adjustment. S An incorrect fuel mixture (too much or in- correct type of oil). S Poor quality gasoline and/or oil S A dirty air filter. These factors cause deposits on the spark plug electrodes, which may result in operating problems and starting difficulties. If the machine is low on power, difficult to start or runs poorly at idle speed: always check the spark plug first before taking any further action. If the spark plug is dirty, clean it and check that the electrode gap is 0.024″ (0.6 mm). The spark plug should be replaced after about a month in operation or earlier if necessary. 0.024″ (0.6 mm) CAUTION! Always use the recommended spark plug type! Use of the wrong spark plug can damage the piston/cylinder. Maintenance schedule Below you will find some general maintenance instructions.
