If you’re a professional landscaper or a homeowner who takes pride in maintaining a well-manicured lawn, you likely understand the value of a reliable backpack blower. However, there’s nothing more frustrating than experiencing issues with starting your backpack blower when it’s hot outside.
This is a common issue with Ryobi backpack blowers, and if left unresolved, it can lead to lost time and frustration. In this blog, we’ll explain why Ryobi backpack blowers might not start when hot and provide tips on how to address this issue.
Causes of the Issue
There are several possible causes that can lead to a Ryobi backpack blower not starting when hot. Some of the most common causes include issues with the carburetor, spark plug, ignition coil, fuel line, air filter, or heat soak.
One of the most common causes of this issue is a problem with the carburetor. Over time, the carburetor can become clogged with dirt, debris, or other contaminants. This can cause the fuel to flow poorly or not at all, which can lead to the engine not starting when hot.
Another possible cause is a faulty spark plug. When the spark plug is dirty, damaged, or worn, it can lead to an incomplete combustion cycle, which can cause the engine to stall or not start when hot. The ignition coil, which is responsible for producing the electrical charge that ignites the fuel in the engine, can also become damaged or worn over time, leading to similar issues.
The fuel line is another potential culprit. If the fuel line is clogged or blocked, fuel may not flow properly, which can cause the engine to stall or not start when hot. Additionally, the air filter can become dirty or clogged, which can cause a reduction in airflow to the engine, resulting in poor performance or stalling.
Heat soak is another common cause of this issue. When the engine heats up, the fuel can become vaporized, leading to poor fuel flow and difficulty starting the engine. This can be exacerbated in hot weather conditions, which can make it difficult to start the engine even when it has cooled down.
It is important to address this issue as soon as possible, as it can lead to poor performance and increased wear and tear on the engine. Regular maintenance, including cleaning and replacing components as needed, can help prevent this issue from occurring. If the issue persists, it may be necessary to seek professional assistance to diagnose and repair the problem.
If your Ryobi backpack blower won’t start when hot, there are several steps you can take to troubleshoot and diagnose the issue. Here is a step-by-step guide for identifying the root cause of the problem:
Check the Air Filter
A dirty air filter can restrict airflow to the engine, causing it to overheat and stall. Remove the air filter and inspect it for dirt, debris, or damage. If it appears dirty or clogged, clean or replace it.
Check the Spark Plug
A faulty spark plug can cause the engine to misfire and prevent it from starting. Remove the spark plug and inspect it for wear or damage. If it appears worn or fouled, replace it with a new one.
Check the Carburetor
A dirty or clogged carburetor can cause the engine to run rich or lean, making it difficult to start or causing it to stall when hot. Remove the carburetor and clean it with carburetor cleaner. If the carburetor is damaged or worn, replace it.
Check the Ignition Coil
A faulty ignition coil can cause weak or intermittent spark, making it difficult to start the engine when hot. Use a multimeter to test the ignition coil for continuity and resistance. If it appears faulty, replace it with a new one.
Check the Fuel Line
A clogged or damaged fuel line can restrict fuel flow to the engine, causing it to stall when hot. Remove the fuel line and inspect it for cracks, leaks, or clogs. If it appears damaged or clogged, replace it with a new one.
Check for Heat Soak
Heat soak occurs when the engine and its components become too hot to function properly. To prevent heat soak, avoid running the blower for extended periods, and allow it to cool down before restarting. If you suspect heat soak is the issue, you can try insulating the carburetor, replacing the fuel lines with ones that have better insulation, or installing a heat shield.
It’s important to identify the root cause of the issue to prevent it from recurring in the future. By following these troubleshooting steps, you can diagnose the problem and take the necessary steps to fix it.
Solutions to the Issue
Once the root cause of the issue has been identified, there are several potential solutions to the problem of a Ryobi backpack blower not starting when hot. Some of the solutions include:
Over time, the carburetor in a Ryobi backpack blower can become clogged with dirt and debris, leading to a rich fuel mixture that can make it difficult for the engine to start when hot. Cleaning the carburetor with a carburetor cleaner can help to remove any debris and improve its performance.
Replacing Spark Plugs
Worn-out spark plugs can cause issues with starting a Ryobi backpack blower, especially when hot. Replacing old or fouled spark plugs with new ones can improve the performance of the engine and help to prevent starting issues.
Replacing Ignition Coils
If the ignition coil is damaged or not working correctly, it can cause a Ryobi backpack blower to not start when hot. Replacing the ignition coil with a new one can help to resolve this issue.
Replacing Fuel Lines
Old or damaged fuel lines can prevent fuel from reaching the carburetor, leading to starting issues when the engine is hot. Replacing the fuel lines can help to ensure that fuel is flowing correctly and reduce starting problems.
Proper Maintenance Techniques
In addition to these solutions, following proper maintenance techniques can help to prevent starting issues with a Ryobi backpack blower. This includes regular maintenance such as checking and replacing the air filter, changing the oil, and inspecting the fuel lines and carburetor.
It is essential to emphasize the importance of following proper maintenance practices to prevent starting issues with a Ryobi backpack blower. Regular maintenance can help to keep the engine running smoothly and prevent issues that can lead to starting problems. By taking care of the equipment, you can extend its life and ensure it continues to work correctly.
To avoid the problem of the Ryobi backpack blower not starting when hot, there are several preventative measures you can take. Proper maintenance and care are crucial to keeping your equipment functioning correctly and extending its lifespan. Here are some tips to help prevent this issue from occurring:
Follow the Manufacturer’s Instructions

Keep the Air Filter Clean
A dirty air filter can cause the blower to overheat and stop functioning correctly. Regularly cleaning or replacing the air filter can help prevent this issue.
Use Clean Fuel
Dirty or old fuel can cause the carburetor to become clogged, leading to starting problems. Always use fresh fuel and store it in a clean, dry place.
Keep the Fuel System Clean
Regularly clean the fuel tank and fuel lines to prevent clogs and other problems. This can help to ensure that fuel flows smoothly to the carburetor.
Use High-quality Oil
Using high-quality oil can help reduce carbon build-up in the engine, which can contribute to starting problems. Follow the manufacturer’s recommendations for oil type and change intervals.
Allow the Engine to Cool Down
If you need to shut off the blower while it’s hot, allow it to cool down before starting it up again. This can help prevent the heat soak issue.
By following these preventative measures, you can help ensure that your Ryobi backpack blower continues to function correctly and avoid the issue of it not starting when hot. Proper maintenance and care are essential for keeping your equipment in good condition and extending its lifespan.
Additional Tips to Help Address the Issue of a Ryobi Backpack Blower
Here are some additional tips to help address the issue of a Ryobi backpack blower not starting when hot:
Use the Correct Fuel Mixture
Ryobi backpack blowers require a specific fuel mixture of gasoline and oil. Using the wrong fuel mixture can cause the engine to run poorly, which can lead to starting issues, especially when the blower is hot. Make sure to use the correct fuel mixture and follow the manufacturer’s recommendations.
Store the Blower Properly
When not in use, it’s important to store the blower properly. This means storing it in a cool, dry place and using a cover to protect it from the elements. Moisture and extreme temperatures can cause damage to the blower, which can contribute to starting issues.
