Common ECHO String Trimmer Issues & Answers
The string trimmer will not turn on.
While troubleshooting a starting issue with your string trimmer, be on the lookout for anything that can impede the air, gasoline, or spark that is necessary to start the engine.
Make sure the fuel is not stale, and that the ratio of gas to oil in the fuel combination is exactly 50 to 1. Since it does not contain any lubrication, running the engine on straight gas will cause it to freeze up.
ECHO string trimmers call for unleaded petrol with an octane rating of at least 89 and an ethanol concentration of no more than 10%, along with a premium 2-cycle engine oil such as Echo Power Blend or Echo Red Armor.

Reasons Your Echo String Trimmer will not turn on.
| Cause | Reason for the Problem | Solution |
| Poor or old gasoline | As time passes, gasoline degrades, which makes the fuel less effective and increases the risk that it may block the fuel system. | The fuel tank should be drained before being refilled with new gas and 2-cycle oil. combine in a proportion of 50 to 1. To prevent the gasoline from deteriorating and to aid in cleaning the fuel system, you should use a fuel additive such as Sea Foam. Use the appropriate fuel. |
| Improper 2-cycle oil mix | If the ingredients are not combined properly, the engine could not get the lubrication it needs. | 50 parts gas to 1 part 2-cycle oil should be mixed together. Use fuel with an octane value of at least 89 and an ethanol percentage of no more than 10%. |
| Defective spark plug | It may not be possible to start the engine if the spark plug is filthy or broken, the spark plug wire is loose, or the gap is improper. | Spark plug should be replaced with new one, connections should be secured, and it should be gapped according to the manufacturer’s recommendations. |
| Plugged air filter | The air filter might get clogged with dirt, restricting airflow. | Take out the filter and give it a good cleaning. If the filter is in poor condition, you should replace it. |
| Blocked fuel filter | If the fuel filter is unclean, the flow of gasoline will be restricted. | It’s time to change the gasoline filter. |
| Blocked gasoline lines | The deposits left behind by old gasoline, along with dirt, have the potential to choke the fuel lines, preventing fuel from reaching the engine. | To remove the blockage from the gasoline line, you may use a carburetor cleaner in conjunction with compressed air. If required, the line should be replaced. |
| Blocked gasoline tank vent | If the vent on a gasoline tank is stopped, the tank will no longer be able to vent. A vacuum will develop, which will prevent gasoline from leaking out of the tank. | Remove and replace any obstructions in the fuel tank vent. |
| Plugged spark arrestor | If the spark arrestor is clogged with soot, then the string trimmer will not be able to release any of its hot air. | It is important to keep the spark arrestor screen clean. |
| An unclean carburetor | As a result of ethanol deposits and contaminated gasoline, the carburetor might get blocked and unclean, which restricts the flow of fuel. | It is important to clean all of the components that make up the carburetor. If it’s broken, replace it. |
| Poor primer bulb | A primer bulb that has been fractured will prevent gasoline from being transported to the carburetor. | It’s time to change the priming bulb. |
| Engine submerged in water | The ratio of fuel to air is excessively high, and as a result, the combination cannot be ignited. This may happen if the priming bulb is pressed an excessive number of times, or if the starting rope is pulled an excessive number of times while the choke is closed. | To start the engine, move the switch to the “run” position. The choke lever has to be moved to the run position. When you are drawing the starting rope repeatedly, you should press the trigger for the throttle. |
| Broken starter recoil | If your recoil is broken or damaged in any way, it won’t be able to turn over and start your engine. | Examine the rebound to see whether or not it can be restrung. It is necessary to repair any damaged components. In the event that it is necessary, replace the recoil assembly. |
The string trimmer begins its operation and suddenly stops.
It’s important to note that many of the same factors that keep an ECHO string trimmer from starting are also among the factors that might cause it to stall out and stop working after it’s already been running.
If you start the trimmer and it immediately stops working, you need to check that you are beginning it properly. Before starting a cold engine, the choke lever has to be moved into the “on” position so that it can limit airflow.
When the engine has reached operating temperature, the key must be turned to the “off” position before the engine may be used again.

| Incorrect adjustment of the choke | Before the engine may be restarted after it has been preheated, the choke lever needs to be shifted to the open position. Only then can the engine be started. | Before starting a cold engine, the throttle should be closed to restrict the flow of air. You are free to open it after the engine has reached operating temperature. |
| Poor gasoline | As time passes, gasoline degrades, making it less effective and increasing the risk that it can block the fuel system or cause harm to the engine. | The fuel tank should be drained and then refilled with a mixture of new gasoline and 2-cycle engine oil in the proportions of 50:1. To prevent the gasoline from deteriorating and to aid in cleaning the fuel system, you should use a fuel additive such as Sea Foam. |
| Plugged air filter | The air filter might get clogged with dirt, which can limit airflow. | Take out the filter and give it a good cleaning. If the filter is in poor condition, you should replace it. |
| Blocked fuel filter | A gasoline filter that is clogged will not enable an adequate amount of gas to flow through it. | It’s time to change the gasoline filter. |
| Clogged gasoline lines | Deposits of contaminated gasoline and dirt may accumulate and block the fuel lines, which prevents the engine from receiving the necessary amount of fuel. | To remove the blockage from the gasoline line, you may use a carb cleaner in conjunction with compressed air. |
| An unclean carburetor | Due to poor gasoline quality and ethanol deposits, the carburetor might get dusty and blocked, which prevents fuel from flowing properly. | It is important to clean each of the components that make up the carburetor. If necessary, either rebuild or replace it. |
| Blocked gasoline tank vent | If the vent on a gasoline tank is stopped, the tank will no longer be able to vent. A vacuum will develop, which will prevent gasoline from leaking out of the tank. | Remove and replace any obstructions in the fuel tank vent. |
| Plugged spark arrestor | It is possible for the spark arrestor to get clogged with soot, preventing the exhaust of hot air. | Take off the spark arrestor screen and give it a good scrub with the metal brush. Replace a screen that has been damaged. |
The string trimmer makes a grinding and stuttering sound.
If the engine of an ECHO string trimmer isn’t receiving enough gasoline, the spark plug is filthy, or there is a blockage in the trimmer’s exhaust system, the trimmer will have a jerky and stuttering performance.

| Old fuel | Deposits of sticky residue are left behind by stale gasoline, which may limit fuel flow and lead to component failure. | Take out the old fuel and put in a mixture of new gas and 2-cycle engine oil in the proportion of 50:1 in its stead. To prevent the gas from deteriorating and to keep the fuel system clean, you should use a fuel additive such as Sea Foam Motor Treatment. |
| Filthy spark plug | It may be running slowly because the spark plug is filthy, which causes the spark to be sporadic. | It’s time to change the spark plug. |
| Blocked fuel filter | If the gasoline filter is clogged, then a normal flow of fuel will not be able to pass through it. | It’s time to change the gasoline filter. |
| Clog gasoline lines | When dirt or old gasoline clogs the fuel line, the amount of fuel that can pass through it is reduced. | The gasoline line should either be cleaned or replaced. |
| Blocked gasoline tank vent | A vacuum is created inside of the gasoline tank whenever it is unable to vent, which prevents fuel from escaping the tank. | Changing out the vent on the fuel tank. |
| obstructed air filtering system | It is possible for the air filter to get clogged with so much dirt that it prevents the necessary amount of air from passing through it. | It’s time to change the air filter. |
| An unclean carburetor | The fuel channels in the carburetor eventually get clogged with old gas deposits, which prevents an adequate amount of fuel from reaching the engine. | Take out the carburetor so it may be cleaned, then replace it. If necessary, either rebuild it or replace it. |
| Plugged spark arrestor | When the spark arrestor is clogged with soot, the trimmer will not allow any of the hot exhaust air to leave the device. | Take out the spark arrestor screen and give it a good cleaning. |
Only with the choke engaged can the string trimmer operate.
If your ECHO string trimmer will only operate with the choke engaged, you need to investigate the possibility that there is anything in the way of the fuel flow or that the air intake is too large. It is possible that the choke on the trimmer has to be engaged in order to fix the fuel-to-air ratio before the mixture can be ignited.
In addition to this, you will need to search for components that are letting an excessive amount of air into the system. If you take in too much air, you will have to utilize the choke to reduce the amount of air that you take in.
