So if you’re ready to tackle the problem, read on and let’s get started!
Short Answer
There could be a few different reasons why a Toro lawn mower won’t start.
It could be that the spark plug has become dirty or disconnected, the fuel could be old or contaminated, or the air filter could be clogged.
Before attempting to troubleshoot the problem, it’s important to make sure the mower is getting enough gas and oil, and that the spark plug is connected properly.
Common Causes of a Non-Starting Toro Lawn Mower
A Toro lawn mower that won’t start can be a frustrating problem.
Luckily, there are a few common causes that can help you narrow down the potential culprits.
A dirty air filter, old or bad fuel, a faulty spark plug, or a clogged carburetor are all common problems that can prevent your Toro lawn mower from starting up.
Dirty air filters can block the flow of air to the engine, preventing it from receiving the oxygen it needs to run.
To check if this is the issue, remove the air filter and inspect it.
If it is filled with dirt and debris, replace it with a new one.
Another common issue is old or bad fuel.
Old fuel can become clogged or stale, preventing it from igniting and allowing the engine to start.
To check if this is the issue, drain the fuel tank and refill it with fresh fuel.
The spark plug is another important component in getting your Toro lawn mower to start.
This small component creates the spark that ignites the fuel in the engine.
If it is worn or corroded, it won’t be able to do its job.
To check if this is the issue, remove the spark plug and inspect it.
If it appears to be in bad condition, replace it with a new one.
The last common issue is a clogged carburetor.
The carburetor mixes the air and fuel together, which the engine needs to run.
If the carburetor is clogged, the engine won’t be able to receive the fuel it needs to run.
To check if this is the issue, use a carburetor cleaner to remove any clogs.
Once all of these components have been checked and adjusted, your Toro lawn mower should start up again.
If you are still having trouble, it may be a good idea to take it to a professional repair shop to have it looked at.
Troubleshooting the Air Filter
When it comes to troubleshooting why your Toro lawn mower wont start, the first thing to check is the air filter.
A dirty air filter can block the flow of air needed to keep the engine running, resulting in a mower that wont start.
To check the air filter, remove the cover and inspect it.
If the air filter is covered in dirt and debris, it needs to be replaced.
If the air filter looks clean, you can try cleaning it with compressed air to remove any debris that might be clogging it.
Once the air filter has been replaced or cleaned, its time to move on to the next step in troubleshooting your mower.
Checking and Replacing the Fuel
If your Toro lawn mower won’t start, checking and replacing the fuel is an important step.
Fuel can go bad quickly, and if it is too old or bad, it can prevent your mower from starting.
To check the fuel, start by looking for signs of contamination such as water or debris.
If the fuel appears to be contaminated, it should be drained from the tank and replaced with fresh fuel.
You should also check the fuel filter as it can become clogged with dirt or debris.
If the filter is blocked, it can prevent fuel from reaching the engine, which can result in a no-start situation.
Clean or replace the fuel filter as needed.
If the fuel is old, it may need to be replaced.
Gasoline should be replaced every two to three months, while diesel fuel should be replaced every three to six months.
To be sure the fuel is fresh, use a fuel stabilizer to extend its shelf life.
This will help ensure that the fuel will not go bad while in storage.
Once you have ensured that the fuel is fresh and not contaminated, it should be added to the tank of your Toro lawn mower.
Make sure to use the proper fuel type for your mower, such as regular unleaded gasoline for most models.
If you are using diesel fuel, you should also add a fuel additive for improved performance and protection from corrosion.
Testing and Replacing the Spark Plug
If your Toro lawn mower wont start, one of the first things you should do is test and replace the spark plug.
The spark plug is responsible for igniting the fuel, so it must be in good working condition for the mower to start.
To test the spark plug, first remove it from the engine and inspect it for signs of wear or corrosion.
If it appears worn, replace it with a new spark plug.
When replacing the spark plug, make sure to use the correct size and type for your mower.
You can find this information in the mowers owners manual.
Before installing the new spark plug, check the gap between the electrodes.
This should be set to the manufacturers recommended gap setting.
If it is not, adjust it using a gap gauge.
Once the spark plug is installed, start the mower again and test for spark.
If the spark plug is working properly, the mower should start up.
However, if the spark plug is still not working, you may need to replace it again or try a different spark plug.
It is also possible that the spark plug is not the cause of the problem and you may need to look at other components, such as the air filter, fuel, or carburetor.
Cleaning the Carburetor
When troubleshooting your Toro lawn mower, one of the areas you should check is the carburetor.
If the carburetor is clogged, it can prevent the engine from starting.
Fortunately, cleaning the carburetor is a relatively simple process that can be done with some basic tools.
Before you begin, you should make sure you have the right tools for the job.
Youll need a carburetor cleaner, a can of compressed air, and a few screwdrivers.
Youll also need a pair of safety goggles and gloves to protect yourself from any debris that might be blown out of the carburetor during the cleaning process.
Once you have the necessary tools, youll need to locate the carburetor on your Toro lawn mower.
On most models, the carburetor is located on the side of the engine and is protected by a plastic cover.
Once you have located the carburetor, you can begin the cleaning process.
Start by removing the plastic cover and the screws that hold it in place.
Once the cover is removed, you can begin to clean the carburetor.
Start by spraying the carburetor with carburetor cleaner.
This will help to loosen and remove any dirt or debris that might be clogging the carburetor.
You can also use compressed air to help remove any stubborn dirt or debris.
Once the carburetor has been cleaned, youll want to reassemble the parts and make sure all of the screws are tight.
Once the carburetor is reassembled, you should be able to start your Toro lawn mower again.
If the problem persists, you may need to take your lawn mower to a professional for further troubleshooting.
Adjusting Other Components
Once you have checked and adjusted the air filter, fuel, and spark plug, there are a few other components that could be causing your Toro lawn mower to not start.
These include the carburetor, the ignition system, and the battery.
The carburetor is responsible for regulating the air and fuel mixture that is supplied to the engine.
If the carburetor is clogged, it can prevent the fuel from entering the engine and cause the mower to not start.
To determine if the carburetor is clogged, remove it from the engine and use a carburetor cleaner to clear any dirt or debris.
The ignition system is responsible for delivering the spark to the spark plug.
If the ignition system is not functioning properly, the spark plug will not be able to ignite the fuel and the engine will not start.
Check the ignition system for any signs of wear or damage and replace any components that appear to be faulty.
Finally, check the battery to make sure it is not dead.
If the battery is dead, the mower will not start.
Use a multimeter to test the batterys voltage and make sure it is above 12 volts.
If it is not, replace the battery with a new one.
Once all of these components have been checked and adjusted, your Toro lawn mower should start up again.
If you are still having difficulty starting the mower, it may be best to take it to a professional for further diagnosis.
