Why Hayter Lawn Mower engine will not start?
- D
  Daniel MckeeAug 17, 2025
  There are several reasons why your Hayter Lawn Mower engine might not start. It could be due to the engine being under load, so try raising the height of cut. Check if the fuel tank is empty and fill it if necessary. If the engine is cold, set the throttle to the ‘choke’ position. Ensure you are using the correct, uncontaminated fuel; if not, drain the tank and refill. Make sure the spark plug lead is connected and the throttle is set to the ‘fast’ position. Check that the engine brake is released by operating the engine brake lever. A faulty spark plug could also be the culprit, so clean and adjust the gap or replace it. Finally, inspect the wiring for any faults.
