A: Spark Plug:

Check the H.T. lead (1 in the diagram) is correctly fitted to the

spark plug.

To check the state of the plug, unscrew the spark plug with a

genuine spark plug spanner. Oil can be cleaned from it (the

result of the machine having been overfilled with oil or tipped

incorrectly) with a clean rag.

A wire brush or emery paper can be used to clean any carbon

deposit from the plug.

Whilst the plug is removed, prime the engine 10 times and pull

the recoil rope 6 times. This will rinse and eject any residue of

oil from within the cylinder head.

Now it would be prudent to check the

air filter:

The filter is located on the left hand side

(viewed from the front). The cover (4)

has a screw to release it at the top.

Remove the cover and then the inner

paper filter. If contaminated with oil or

fuel, it will need to replaced. Clean the

cover and housing from any excess oil.

Replace the filter.

If you wish to test for a spark (2 people required):

1. Stand the machine on a firm surface and set the height adjusters to the lowest

setting for added safety.

2. Remove the H.T. lead – a push fit.

3. Unscrew the spark plug with a genuine spark plug spanner.

4. Fit the plug back into the end of the H.T. lead and rest it against the engine block

(hold only the black insulation lead).

5. The second person can now hold in the Operators Presence Control and pull the

engine cord. You should see a spark jump across the end of the plug.

The spark plug gap should be 0.76mm or 0.03” (

1000

Replace the plug and ensure the H.T. lead is correctly fitted to the spark plug.

NOTE: If there is no spark, change the plug. If there is still no spark

refer to a service dealer because the coil may be faulty.
