Roary the Repair Lion says:

Reasons for Failure:

1. Engine Overheating - Check engine fan is not damaged (behind the recoil) and be sure there is sufficient airflow around the engine
2. Flywheel hitting the Ignition Coil - Check crankcase bearing and Crankshaft Oil Seal
3. Rusting - Rusting due to the metal components required for the production of a spark

Testing Procedure:

How to test your ignition coil:

1. Remove the ignition coil and spark plug.
2. Using a multimeter, set it to Ohms, and test across with the negative touching the Metal coil end, and the positive to the spark plug cap connection inside (without spark plug fitted.) Write down the results. Ideally, you should get 6 K-ohms, to indicate all is well.
3. Now test from the Metal part of the ignition coil to the spade terminal at the end of the thin wire. Ideally, you should get 2.7 ohms, to indicate all is well.

If either of the above results is lower or higher, you need to replace the Ignition Coil.

How to test the Oil Alert Unit CDI Controller:  Be sure the oil is filled to the top, unplug the wire protruding from the engine just above the oil filler that connects to the "Oil Alert Unit CDI Controller" and try to start the engine again.

 Oil Alert Unit CDI Controller

• If it starts, you need to replace the Oil Alert Unit CDI Controller and do not need to replace Ignition Coil. Do not run the engine without the Oil Alert Unit CDI Controller. You must replace this part to protect your engine.
  
• If it does not start, then we suggest you replace the Ignition Coil and the Oil Alert Unit CDI Controller as this often degrades and can be damaged by a failing Ignition Coil.

How to test the Spark Plug, we suggest having a look at this video.

Repair Tips:

It is very hard to fit the Ignition Coil without the magnetism on the flywheel pulling on the part. A great way to work around this is to use a standard paper business card.

1. Place the business card over the flywheel (NOT where the magnet sits)
2. Fit the ignition Coil so the curve faces towards the Flywheel and sits on the business card
3. Tighten the bolts
4. Turn the flywheel to remove the business card
5. The Ignition Coil should now be set in the correct place. Turn flywheel to be sure the magnet does not connect with the ignition coil. If it does touch, repeat the process until it is set correctly and clears the flywheel. You might need to use additional business cards if the card was very thin.
