This small component is responsible for creating the spark that ignites the air-fuel mixture, and if it fails, the engine will not turn over properly. A low compression reading usually indicates worn piston rings or damaged cylinder walls, but more commonly on a mower, it is caused by a loose or misadjusted connecting rod, or a broken recoil starter spring.
Common Causes and Fixes for a Husqvarna Mower That Won't Start
Fuel System: The Most Common Culprit More often than not, a Husqvarna mower won't start because of a problem with the fuel going to the engine. A clogged filter restricts airflow, causing the engine to run rich and potentially flood the spark plug, making starting difficult or impossible.
Equally important is ensuring the fuel cap's vent hole is not obstructed; a vacuum can form inside the tank as you run the engine, preventing any more fuel from flowing to the carburetor and causing the engine to sputter and die. Before you consider the expense and hassle of a service call, a systematic check of the machine's basic systems will often get you back to mowing in minutes.
