For causes and remedies refer to high lub oil consumption section.
  1. It is normal
  1. Clean spark plug electrode tips. Set gap. Connect it to HT lead. Earth its body. Turn ignition switch 'ON'. Ensure 'Kill' switch is in 'RUN' Position. Crank the engine. How is the spark?
  1. No Spark
  • Defective spark plug.
  • Defective plug cap.
  • Open primary circuit.
  • Defective H.T Coil
  • Change the plug.
  • Change the cap.
  • Check and correct.
  • Change the H.T. Coil
  1. Red/Yellow Spark

  2. Right compression heats up the air petrol mixture. Light blue spark at the right time ignites it and the engine starts.
  3. Right compression pressure for bullet 6.5 kg/cm2 to 8.5 kg/cm2
  4. Check ignition coil as follows : Remove spark plug cap from H.T lead. Turn ignition switch 'ON'. Hold the lead end abouy 8mm away from cylinder head. Crank the engine. Continuous light blue spark jumping from the lead indicates the primary circuit and the HT coil are OK.
