The engine will not shut down:
Turn off the fuel – and let the engine stop by running out of fuel.
The ignition switch is not earthed:
Test the circuit or take to your service agent
The engine stops suddenly:
Check to see if the fuel tank is empty.
Check the fuel is flowing, if not, clean the fuel filter.
Ensure the breather hole in the fuel cap is not clogged.
Check that water, dirt or gum hasn’t contaminated the fuel.
(In certain conditions condensation can occur inside the fuel tank causing droplets of
water that can accumulate at the bottom of the Fuel Tank.)
Check the spark plug lead is undamaged and in place on the plug.
Check the spark plug isn’t oiled or carboned up, check spark by removing
the plug from the engine, reattach the lead and, while resting the spark
plug thread against the engine body, turn over the engine by pulling on
the starter cord. If a spark isn’t seen, try a new plug. If this fails see your
service agent.
(NOTE: DO NOT hold the plug in the hand as the high voltage will cause a painful electrical shock.)
The engine is hard to start:
Weak spark, faulty Spark plug or Spark plug lead Choke has not been set
correctly – must be closed on initial start-up.
Using old fuel that has been stored too long, or poor quality fuel.
Blade impact on a solid object may have bent the crank shaft or snapped
the Woodruff Key.
