Echo weed eater won't start

It mainly happens due to the following 4 reasons:

  • Bad fuel.
  • Clogged fuel filter
  • Faulty spark plug
  • Clogged carburetor

Before we move onto further details, let us give you a brief idea about the Echo weed eater and its various features to better understand its problems.

ECHO is a quite well-regarded brand specializing in garden equipment like weed trimmers. It is known for its efficiency and speed as it can chop through weeds at a good speed.

They also add great value taking into account both price and performance.

While they are generally very durable, problems may still happen. This article will gloss over some of the reasons why it’s not working along with fixes.

Most of these are very simple and straightforward issues that can be solved in moments.

Bad Fuel Quality

Like any machine, the quality of fuel used plays a crucial role in the performance of the Echo Weed Eater. Ideally, you should use ethanol-free fuel for an engine this compact, to minimize any damages.

However, gradually using lower quality fuel will bog the engine down and one day, the engine may not start at all.


Give your machine a fresh start by draining all the oil present within the tank. After you have done that, put back fresh oil in the tank.

You should look for an ethanol-free oil mixture. You can either buy any name-brand pre-mixed fuel or mix your own fuel.

Clogged Up Fuel Filter

The fuel filter plays a vital role in trapping the impurities and keeping them away from the engine. This lets clean oil pass through.

However, along the process, the filter itself may get clogged up by impurities or debris. That will hamper the flow of oil and potentially cause starting issues.

A common mistake people make is creating a different route for the fuel bypassing the fuel filter altogether. Unfortunately, this causes even more damage to the engine itself.


The first thing you must do is remove the fuel filter. Grab the right tools and remove it from its place. In some cases, you can clean the debris, while in others, you have to buy a replacement oil filter.

They are relatively inexpensive and easy to replace.

Issues with Spark Plug

The spark plug, like the name, clearly suggests, is a plug that ignites or sparks a flame needed for the engine to start.

These small plugs create a passage for electricity in the engine.

Sometimes the spark plugs can be blown due to a number of reasons. You can quite easily check if that’s the case, but it requires some caution.

First, remove the insulated boot from the terminal of the spark plug. Next, you’ll need to use a special wrench to remove the spark plug.

Finally, once you have replaced and reinstalled the spark plug, place it by the metal part of the engine without touching it.

There should be a visible blue spark on the end of the plug if the placement is correct.

Make sure to check the spark plugs every once in a while, as they are crucial to ensure that the engine turns on properly.

Clogged Up Carburetor

Sometimes, due to the inefficiency of the fuel filter, the carburetor itself can get clogged up with dirt and debris.

This will most certainly cause performance issues, and in that case, the Echo Weed Eater may start but will be unable to hold power.

Sometimes, the fuel to air mixture in the engine could be messed up. You can adjust the level using the adjustment screws in the carburetor.

However, it is more common that the carburetor is clogged up, which might be causing starting issues. Therefore, your next step should be to clean it thoroughly.


To clean the carburetor, you will need ideas on what to do as well as the right tools. First, get a good dilute cleaner and a brush that will fit within the carburetor.

Next, remove the carburetor float and use the cleaning apparatus to thoroughly clean out any dust and debris.

Once you have cleaned it properly, rinse it and let it dry. After you are done, reattach the carburetor back in the engine.

Few Extra Things

The issues we mentioned above are considered a few of the most common reasons why the weed eater won’t turn on. Of course, these are not the only reasons, but these are a few of the more probable causes behind the issue.

The fixes mentioned here can be applied by almost anyone, as they require a minimal level of expertise or additional tools.

By knowing the how-to, you can possibly save a lot of money that would otherwise be spent buying a new weed trimmer.
