Most Frequent Causes for Lawn mower won't start

Cause 1Old or Bad Gasoline

There may be old or bad fuel in the carburetor float bowl. Over time, some of the ingredients in the fuel may evaporate, leaving behind a thicker, stickier substance. This sticky fuel can clog up the carburetor and prevent the engine from starting. If the carburetor is clogged, try cleaning it with carburetor cleaner. If cleaning the carburetor isn’t effective, rebuild or replace the entire carburetor.

Cause 2Safety Switch

To determine if the safety switch is defective, use a multimeter to test it for continuity.
