This is Why Your ECHO Leaf Blower Has No Power (SOLVED)

When your ECHO blower isn’t giving you the same amount of power it once did, you need to figure out the problem. Your blower doesn’t just help pick up leaves in the fall. It’s a great tool to use year round for blowing off the patio, drying your outdoor equipment, blowing light snow and so much more.

An Echo leaf blower has no power when the engine isn’t getting sufficient fuel, air or spark. This can be caused by a plugged filter, clogged fuel line, faulty fuel tank vent, bad spark plug, plugged spark arrestor or dirty carburetor.

Before working on your ECHO blower, make sure the engine is not hot and you follow all safety precautions to prevent injury. You can find these safety precautions listed in your operators manual.

Reasons an ECHO leaf blower has no power:

  • Old gasoline
  • Plugged air filter
  • Dirty spark plug
  • Plugged fuel filter
  • Clogged fuel line

8 Reasons Your Echo Leaf Blower Has No Power

Old Gas Will Cause Your ECHO Blower to Have No Power

The fluids you put in your ECHO leaf blower are extremely important to keep it in operating at it’s best. Spending a little time to understand the right fuel to use in your ECHO blower and the negative effects using the wrong fuel can have on your blower will help you make the best decision for your fuel needs.

Negative effects of gasoline on your ECHO blower:

First, let me start off with explaining some of the negative effects gas can have on your ECHO blower. Most gas contains ethanol which is an alternative fuel added to gasoline to make it a little environmentally friendly.

Ethanol attracts moisture from the air. When this moisture collects in the fuel system, it can cause corrosion. Ethanol and water will leave behind a varnish and gummy deposits that restrict fuel flow by clogging of the fuel lines and carburetor.

The ethanol and water mixture will also separate from the gas over time and run very hot through the engine potentially causing problems. Most people don’t realize that gas can go bad pretty quick. It’s best to consume the amount of fuel you purchase within 30 days.

If you add a fuel stabilizer to your gas, your tank of fuel will last longer before breaking down. Many types of 2-cycle premium oil that is mixed with gas for your 2-cycle ECHO blower includes a fuel stabilizer. However, you need to read the label to determine how long the fuel will be stable when using oils that contain a stabilizer.

ECHO premium oils sold as ECHO Power Blend and ECHO Red Armor include fuel stabilizers. ECHO Power Blend will keep fuel stable for up to a month while ECHO Red Armor will stabilize fuel up to 2 years.

Right Fuel to Use in Your ECHO Blower:

The lineup of blowers ECHO currently sells use 2-cycle engines which require a gas and oil mix at a ratio of 50:1. This means you need to mix 50 parts of gas to 1 part oil.

Because of the harmful effects of ethanol, you must use an unleaded gasoline with a minimum octane-rating of 89 and a maximum ethanol content of 10% (E10) in your ECHO blower. Never use gasolines with higher ethanol contents like those sold as E15, E30 and E85 fuels which contain up to 15%, 30% and 85% ethanol respectively.

Add a premium 2-cycle oil from ECHO or a 2-cycle oil that is ISO-L-EGD and JASO M345 FD certified. Read more about the right fuel for your ECHO leaf blower in “This is the Type of Gas Echo Leaf Blowers Use.

Solution: Drain the old fuel remaining in your leaf blower and fill with fresh fuel. Add a fuel stabilizer like Sea Foam Motor Treatment to stabilize the fuel, reduce moisture and clean the fuel system.

Plugged Air Filter Will Cause Your ECHO Blower to Have No Power

When the air filter becomes plugged with the dirt and debris that gets tossed in the air from running a leaf blower, it will restrict airflow. It may have so much dirt buildup that air isn’t able to pass through the filter at a sufficient rate causing your ECHO to lose power.

To prevent running into this problem, replace your air filter once a year and clean it several times throughout the lawn care season.

Solution: If you find your ECHO air filter is plugged, I recommend replacing the filter. A filter is usually not very expensive. It is an important component when it comes to protecting the engine.

ECHO uses many different types and sizes of air filters depending on the model and type of leaf blower you use. An excessively dirty or damaged filter should be replaced. If you choose to clean your filter, follow these tips:

A foam, fabric or felt style filter can be cleaned using a mild dish soap and water. Wash the filter to remove as much dirt as possible. Rinse until clear and allow it to air dry.

A paper filter can be cleaned by knocking it against a solid surface to remove as much dirt as possible. Hold it up to a light source to see if you can see light through the element. Reuse the filter if you can still see light. Replace the filter if you cannot see light, your filter remains very dirty or it is covered in oil.

Dirty Spark Plug Will Cause Your ECHO Blower to Have No Power

A fouled spark plug can cause your ECHO blower to lose power. A damaged spark plug or one that is dark in color due to being excessively dirty must be replaced. If your spark is in good condition and a little dirty, remove the dirt using a wire brush.

I recommend replacing your spark plug annually to help minimize spark plug issues through the season. A spark plug is an inexpensive maintenance part. Without a good spark plug, you can run into power loss problems with your ECHO.

Solution: Remove the spark plug and replace the plug when you find it is dirty or damaged. Make sure the new spark plug is gapped to the manufacturer’s specification.

Securely attach the spark plug wire (boot) so it makes a good connection. A loose wire can cause your blower to fail to start, stop running or lose power.

Plugged Fuel Filter Will Cause Your ECHO Blower to Have No Power

The purpose of the fuel filter on your ECHO blower is to screen the fuel as it enters the fuel line to prevent dirt and other debris from being introduced into the fuel system. When the fuel filter isn’t changed out regularly, the filter can become plugged.

This will restrict the amount of fuel that is able to pass through the filter which can be the reason you begin to experience a loss of power when operating the blower. When the engine doesn’t get enough fuel, it will bog down.

Solution: Replace a fuel filter that isn’t allowing gas to pass through it and into the fuel line. The fuel filter is located in the fuel tank. To get to the filter, first wipe the area around the fuel cap to remove dirt and debris to prevent it from falling inside the tank.

Pull the fuel filter out of the tank. A clean bent wire works well for this. Remove the filter from the fuel line. Do not allow the retaining ring to come off the fuel line.

Insert the new fuel filter into the fuel line and secure the fuel line to the filter using the retaining ring. Place the filter inside the fuel tank and install the fuel cap.

Clogged Fuel Line Will Cause Your ECHO Blower to Have No Power

The fuel line can become restricted with gummy deposits left behind from using old fuel through your leaf blower. Dirt could have also gotten into the fuel system causing blockages. This can prevent a good flow of fuel to the engine resulting in a power loss.

Solution: Inspect the fuel line looking for any clogs preventing fuel flow. Replace a fuel line that is clogged, kinked or has developed cracks from age.

Plugged Fuel Tank Vent Will Cause Your ECHO Blower to Have No Power

The fuel tank must be vented to equalize the air pressure in the tank. When the vent is clogged on your ECHO, a vacuum will form and fuel will not be able to flow out of the tank. You will find the tank vent connected to the fuel line coming out of the fuel tank.

Solution: If your ECHO blower begins to bog down and lose power, place it on a level surface. Loosen the fuel cap and allow your blower to run. If your blower no longer runs sluggish and loses power once air is introduced to the fuel tank, you most likely have a plugged fuel tank vent. Replace the fuel tank vent.

Plugged Spark Arrestor Will Cause Your ECHO Blower to Have No Power

The spark arrestor is a small metal screen that prevents hot exhaust material from leaving the muffler and starting a fire. When this small screen becomes plugged on your ECHO blower you may experience a loss of power where it won’t run at full RPMs.

Solution: Disconnect the spark plug wire. Make sure your engine is not hot. Remove the engine cover and the engine exhaust cover. Carefully remove the spark arrestor screen. You can either clean it with a metal brush or a torch.

If you choose to use a torch, protect your hands and eyes. Hold the screen away from your body using needle nose pliers. Torch the screen to burn off soot buildup. Do not torch it for too long or you can damage it.

Wait for the screen to cool and reinstall it. Reattach the engine exhaust cover and engine cover. Reattach the spark plug wire.

If the screen isn’t able to be sufficiently cleaned or you find it is damaged or has a hole in it, replace it with a new spark arrestor screen.

Carbon Buildup on the Exhaust Port Will Cause ECHO Blower to Lose Power

The exhaust port located behind the muffler can develop carbon deposits that can cause your leaf blower running problem. This area should be checked and cleaned.

Solution: Start by disconnecting the spark plug wire. Once this is done proceed with removing the engine cover, the muffler and the heat shield. Adjust the piston until it covers the port opening. This will keep carbon from falling into the cylinder.

Use a plastic scraper to remove the carbon buildup around the exhaust port. DO NOT use a metal tool. Do not scratch the piston or the cylinder during this process.

Dirty Carburetor Will Cause Your ECHO Blower to Lose Power

The carburetor regulates the amount of fuel that is mixed with air to create a combustion in the cylinder. Old fuel will gum up and clog the carburetor so it no longer functions properly.

Solution: If you are a little mechanical you should be able to handle cleaning your carburetor. Clean the carburetor by taking it apart and using carburetor cleaner to clean it. If the carburetor does not function after being cleaned, you may need to rebuild it or replace it with a new carburetor.

Depending on the model leaf blower you own, the age of the blower and the price of the carburetor, it may be best to invest in a new leaf blower rather than put money towards replacing a carburetor on an old blower.

When to Have a Mechanic Repair Your ECHO Leaf Blower?

If you have checked the items listed above for your lack of power problem and this didn’t solve your problem, it is time to have a professional mechanic diagnose and repair your ECHO leaf blower.

You may also not feel comfortable performing repairs on your blower. That is okay. That’s why there are small engine mechanics at your local ECHO dealership to assist you.

Keep in mind the labor rate for the mechanic to diagnose your problem. There is typically a flat rate charge to diagnose the problem and then additional labor and parts fees in addition to the fee to make the repairs.

This may not make sense if you are running an old inexpensive leaf blower that’s on its last leg. Keep this in mind so you don’t get surprised when you get a diagnostics bill for a leaf blower that may not be worth repairing.

Having your ECHO leaf blower repaired by a mechanic is a personal decision that only you can make. You have the weigh the reliability, quality and age of your current leaf blower against the cost to repair it and the cost to purchase a new leaf blower.
