Usually when the engine won’t start, the problem is in the fuel supply or the spark plug.
Check that the plug lead is making good contact with the spark plug. Also check that the shut-off switch is in the on position, and that fuel is reaching the spark plug. If the fuel is being delivered and the spark plug is working, the engine may be flooded.
If the problem persists, we recommend you contact your local dealer. A list of dealers is available under Service locator above.
