The Basics: Fuel, Spark, and Air
The most common reason for a lawn mower failing to start is a lack of one or more of the essential elements for combustion: fuel, spark, or air. Let’s delve into each of these aspects.
Fuel: Is It Fresh and Flowing?
1. Check the Fuel:
A stale fuel supply can cause starting issues. Old gasoline can gum up the carburetor and prevent proper fuel flow. Always use fresh, high-octane gasoline, and consider adding a fuel stabilizer to prevent fuel degradation.
2. Inspect the Fuel Line:
Cracks or kinks in the fuel line can impede fuel delivery to the carburetor. Carefully examine the fuel line for any damage.
3. Check the Fuel Filter:
A clogged fuel filter can restrict fuel flow. Inspect the filter and replace it if necessary.
Spark: Does Your Engine Have a Spark?
1. Test the Spark Plug:
A faulty spark plug can prevent the engine from igniting the fuel-air mixture. Remove the spark plug, attach it to the spark plug wire, and ground the metal part of the spark plug to a metal component of the engine. Turn the engine over and check for a bright blue spark.
2. Inspect the Spark Plug Wire:
Cracks or damage to the spark plug wire can interrupt the flow of electricity to the spark plug. Examine the wire for any signs of wear or deterioration.
Air: Is the Air Filter Clean?
1. Clean or Replace the Air Filter:
A dirty air filter restricts airflow to the engine, affecting combustion. Remove the air filter and clean it with compressed air or replace it with a new one.
Beyond the Basics: Exploring Further Potential Issues
Once you’ve ruled out the basic fuel, spark, and air issues, there are several other factors that could be preventing your Toro lawn mower from starting.
Carburetor Problems: A Common Culprit
1. Dirty Carburetor:
Over time, debris and varnish can accumulate in the carburetor, obstructing fuel flow. You can try cleaning the carburetor yourself or consult a professional for more extensive cleaning or rebuilding.
2. Incorrect Fuel-Air Mixture:
An incorrect fuel-air mixture, often due to a worn-out or misadjusted carburetor, can cause starting problems. Adjusting the carburetor settings can sometimes resolve this issue, but seeking professional assistance is often recommended.
Starting Issues: Understanding the Different Types
The way your Toro lawn mower won’t start can offer valuable clues about the underlying issue.
1. Engine Won’t Turn Over:
If the engine doesn’t even try to turn over, the issue likely lies with the starting system.
1. Check the Battery:
For electric start mowers, a dead battery is the most common culprit. Check the battery terminals for corrosion and try jump-starting the mower.
2. Examine the Starter Motor:
Inspect the starter motor for any signs of damage or malfunction.
2. Engine Turns Over but Won’t Start:
If the engine turns over but doesn’t fire up, the problem likely lies with the fuel, spark, or air systems. Refer to the sections above for troubleshooting steps.
3. Engine Starts but Dies Immediately:
This is often a sign of a fuel delivery problem, a malfunctioning carburetor, or an air leak in the intake system.
Taking Care of Your Toro Lawn Mower for Longevity
Preventing starting issues is crucial for maintaining a reliable Toro lawn mower.
Regular Maintenance is Key
1. Perform Routine Maintenance:
Follow the manufacturer’s recommended maintenance schedule, including oil changes, spark plug replacement, and air filter cleaning.
2. Store Properly:
During the off-season, store your Toro lawn mower in a dry, clean area. Ensure the fuel tank is empty or filled with fresh fuel containing stabilizer.
Seek Expert Assistance When Needed
If you’re unable to identify or resolve the starting issue on your own, it’s always best to seek professional assistance. A qualified lawn mower mechanic can diagnose the problem and provide the necessary repairs.

Regular maintenance and proper storage are crucial in preventing future starting problems. If you’re still facing difficulties, don’t hesitate to consult a professional for expert assistance. With a little effort and troubleshooting, you’ll be back to enjoying the satisfaction of a well-maintained lawn, powered by your trusty Toro lawn mower.
Frequently Asked Questions
Why Won’t My Toro Lawn Mower Start?
This is a common issue that can be caused by a variety of factors, such as a dead battery, a clogged carburetor, or a faulty spark plug. To troubleshoot the problem, start by checking the basics, such as the fuel level and the spark plug condition. If these are in order, you may need to clean the carburetor or replace the spark plug.
If you’re still having trouble, consult your owner’s manual or contact a Toro service center for assistance.
How Do I Check If My Toro Lawn Mower Battery is Dead?
To check if your lawnmower battery is dead, simply turn the key to the “on” position and listen for a clicking sound. If you hear clicking, the battery is probably dead. If you don’t hear clicking, the battery might be fine, but there might be another problem with the starter. You can also use a voltmeter to check the battery’s voltage.
A fully charged battery should have a voltage of around 12.6 volts. If the voltage is below 12 volts, the battery is probably dead and needs to be replaced.
What Do I Do If My Toro Lawn Mower Won’t Start After Changing the Spark Plug?
If your Toro lawn mower won’t start after changing the spark plug, there are a few things you can check. First, make sure that the spark plug is installed correctly. The spark plug should be screwed in all the way, but not too tight. If the spark plug is not installed correctly, it may not be making a good connection.
Second, check the spark plug wire to make sure it is connected to the spark plug. If the wire is loose or disconnected, the spark plug will not be able to fire. Finally, check the gap between the spark plug electrodes. The gap should be set according to the manufacturer’s specifications.
How Do I Clean the Carburetor on My Toro Lawn Mower?
Cleaning the carburetor on your Toro lawn mower can be a bit tricky, but it’s not too difficult if you follow the right steps. First, you’ll need to disconnect the fuel line and remove the carburetor from the lawn mower.
Then, you’ll need to disassemble the carburetor and clean all of the parts with a carburetor cleaner. Be sure to pay attention to the small jets and passages. Once all of the parts are clean, reassemble the carburetor and reinstall it on the lawn mower.
What If My Toro Lawn Mower Starts But Then Dies?
If your Toro lawn mower starts but then dies, the problem is likely with the fuel system. The most common culprits are a clogged carburetor or a faulty fuel pump. To troubleshoot the problem, start by checking the fuel level in the tank. If the tank is empty, simply refill it and try to start the mower again.
If the tank is full, the problem may be with the carburetor. You can try cleaning the carburetor, or you may need to replace it. If you’re not sure how to clean or replace the carburetor, it’s best to take your lawn mower to a qualified repair technician.
My Toro Lawn Mower Is Making a Clicking Sound But Won’t Start. What’s Wrong?
A clicking sound but no start is often a sign of a dead battery. The starter motor is trying to engage but doesn’t have enough power to turn the engine over. First, try jump-starting the battery from another vehicle. If it starts, you have a weak battery that needs replacing. If jump-starting doesn’t work, the problem could be with the starter motor, the battery cables, or the starter solenoid.
For these issues, professional assistance might be needed.
