Why won't my Hayter 455E engine start?

If your Hayter Lawn Mower engine won't start, several factors could be the cause. First, check if the fuel tank is empty or contains stale fuel; if so, drain and refill it with fresh petrol. If that doesn't work, make sure the throttle lever is in the Choke position. Also, verify that the wire is securely connected to the spark plug. Finally, inspect the spark plug for pitting, fouling, or incorrect gap; adjust the gap if needed, or replace the spark plug if it's damaged.
