  Emily FosterAug 19, 2025
  If your Hyundai Lawn and Garden Equipment engine is running poorly, several factors could be responsible. A bad spark plug could be the cause, so replace it. A dirty air filter can also lead to poor performance, so replace it. The carburettor might be out of adjustment; in this case, you can try to adjust it, or take the unit to an authorised service centre. Lastly, stale petrol can cause issues, so drain the old petrol and replace it with fresh fuel.
