If you need a new mower, come shop with us in Sherman, TX! We welcome our neighbors from Plano and McKinney.
Checking the Fuel
First, check the fuel. An empty gas tank is the most likely culprit when your lawn mower engine won't start. If there's still plenty of fuel in the tank, consider when you last filled it. If it was over a month ago, drain the tank and add fresh fuel. Gasoline breaks down faster than you might expect, and old fuel can affect the performance of your lawn mower engine. To make your fuel last longer, you can treat it with a fuel stabilizer.
Checking the Oil
Next, check the oil. Your lawn mower's oil should be replaced every season or after about 25 hours of operation, whichever comes first. Wait for the engine to cool down before checking the oil to get the most accurate reading. If the oil has a lot of contaminants, it may indicate a serious problem with the engine that will require a mechanic's attention.
Checking the Spark Plug
If the fuel and oil seem fine, check the spark plug. Spark plugs need occasional adjustment, as they can loosen over time and cause the engine to fail. They should also be replaced every season, so be sure to tighten or replace the spark plug as necessary.
Still Not Starting?
For other issues that may cause your lawn mower engine to fail, such as problems with the ignition system, compression system, or valves, it's best to seek the expertise of a technician.
