What to do if there is no spark in the Zenoah G240RC Engine spark plug?
- D
  Danny SharpAug 29, 2025
  If there's no spark in the spark plug of your Zenoah Engine, several issues could be the cause. The spark plug electrodes might be wet (make them dry), or have carbon deposits (clean them). The insulator may be damaged (exchange it), the spark gap might be improper (adjust to 0.6~0.7mm), or the electrodes may be burnt out (exchange them). Other potential causes include a failure of the ignition coil (exchange it), a damaged or disconnected cable (exchange or repair), the switch being OFF (turn it ON), switch failure (exchange it), or the primary wiring being earthed (repair).

  Michael Davis DDSSep 5, 2025
  If your Zenoah Engine is overheating, it could be due to several reasons. The fuel might be too lean (adjust carburetor), the cylinder fin might be clogged with dust (cleaning), or the fuel quality might be poor (exchange with proper fuel). Overheating may also be caused by carbon deposits in the combustion chamber (cleaning) or a red hot spark plug electrode (thoroughly clean, adjust spark gap [ 0.6~0.7(0.023~0.028in) ]).
