Husqvarna Weed Eater Won’t Stay Running: What Are The Common Causes?

Husqvarna Weed Eater seems to have become too familiar to many families in the process of gardening or pruning.

And perhaps you encountered problems while using the machine, especially stopping during machine operation.

So, we believe you are also interested in Husqvarna weed eater troubleshooting. Let’s read on to know more details!

Husqvarna Weed Eater Overview

First and foremost, when it comes to the cause or fix for a malfunction, we always recommend that users first learn about the product.

Of course, the Husqvarna will be no exception. We will provide basic information about this machine. The essential thing we think you should know about the engines of the Weed Eaters on the market today.

Usually, Weed Eater engines have two main types, engine 2 and engine 4. If engine 2 uses gasoline mixed with viscous fuel, engine 4 is with an independent oil and fuel tank.

About the Husqvarna Weed Eater, it runs on an internal combustion engine, as we mentioned above.

The brand also offers available alkylate fuel with good quality and low in harmful chemicals. It is one of the significant advantages that we would like to introduce to you.

Working Mechanism Of The Machine

Once you have mastered the basics of this Weed Eater, it is essential to understand more about the machine's operating mechanism.

The device works on the principle of giving the nylon line a strong enough rotation through centrifugal force to act on the motor and the zipper.

Then the operator's task is to rotate the trimmer to the position of the tree to be pruned.

In addition, as we mentioned earlier, the Husqvarna has a two-stroke engine operating principle. So the machine will work similarly to many other Weed Eaters on the market.

To ensure that a full cycle of operation can be completed, the device will be divided into two stages during the process and depends mainly on the movement of the piston.

We have provided the necessary operating information of the machine. Of course, we won't waste too much of your time. Let's find out more about why the engine stops running and how to solve it.

Causes Of Husqvarna Weed Eater Not Running

Here are some common causes for this condition that you should be aware of. With each, you will have different treatment directions.

Fuel usage problem

We think that fuel usage is one of the most common causes.

Do you know that using the wrong fuel can cause engine damage and make them unable to run? In addition, we believe that the use of weed eaters is not too frequent.

Therefore, the fuel left behind from the previous use will no longer be of good quality, so it will significantly affect your subsequent use, especially if you choose a terrible fuel.

So, the first solution you should consider is to choose an excellent and quality material for your machine. We suggest that when choosing gasoline, select the one that contains the maximum 10% ethanol content and is unleaded.

However, to increase the time of use of the machine, you should consider using Husqvarna two-stroke oil.

Spark plug problem

Spark plug problem

Next, we want to mention the spark plug, an essential part of the machine's engine operation. The spark plug is responsible for providing the spark and igniting the fuel in the combustion chamber.

So what could be the problem you have with the spark plug? As you guessed, it's your spark plug that becomes depleted and stops providing sparks.

The most helpful advice we would like to give you is to choose a resistor plug instead of an ignition plug.

There are also three possible malfunctions you will encounter with spark plugs:

  • Your spark plugs may get dirty or wet at first: always make sure to keep your spark plugs clean.
  • Next is the possibility that the electrode gap of the spark plug is misaligned: what you need to do is still make sure the spark plug is clean.
  • Your spark plugs may eventually come loose, so make sure you tighten the spark plug.

Air filter problem

When the machine is too long, the air filter is one of the most easily affected parts. It is easy to see that dust and garbage will stick around the air filter.

Air filter problem

You probably already know that the filter is cylindrical, quite small, so, understandably, it will clog.

But don't worry too much, what we need to do is clean it up. You can use alcohol or kerosene, or even water to clean them. Also, make sure the filter is dry and check it thoroughly before reinstalling it in its original position.

In addition, you should also consider replacing a new air filter when your filter has been available long enough.

Gas tank vent

Any Weed Eater has a small vent hole in the fuel tank. It has the critical job of helping to prevent the formation of a vacuum in your gas tank.

However, sometimes the air vent becomes clogged, and you need to know how to check it. Simply, when the trimmer is running, you need to loosen the air cap.

If you find that the machine is running better, then the vent is probably stuck, and you need to replace the cover with a new one.

In addition, a small tip you should know is that you should not pour more fuel than the required line because there will be no space for the air vents to work. So use good energy while providing just enough gas for your engine.

Malfunction due to seals and washers

The main job of seals and washers is to prevent your engine from leaking by fuels like gasoline or oil.

It has a significant effect on whether the engine is working or not. So although these two parts are quite small, you need to pay more attention to them. Replace it if you want.

Problems from engine cover and cylinder

Malfunctioning engine cover and cylinder will cause your engine to stall. One of the problems you have is that the cap mounted on the engine is not secure.

Problems from engine cover

It easily comes off the machine. Plus, a loose cylinder causes your engine to start but then stop suddenly.

Usually, this problem does not have a significant impact on the operation of the machine. So you just need to pay more attention to the device only.

In addition, this Husqvarna Weed Eater has a pretty good muffler, but you also need to remove and clean it regularly.

Carburetor fault

Last and not least affecting the sudden stop is the carburetor. The carburetor is responsible for dividing the amount of gasoline into the combustion chambers, which must be an essential task, right?

So if your Weed Eater has a faulty carburetor, it will stop delivering fuel to the combustion chambers, which means stopping the functions of other essential components such as spark plugs, combustion chambers, etc. And that's why your engine can stop working.

So what is the best fix for this case? The first thing you need to do is take out the carburetor and clean it, then use a specific cleaner to spray it.

Make sure you have cleaned every nook and cranny of this carburetor. Like the air filter, you need to dry it to prevent leaks before putting it back in the machine.

Notes For Safe Use Of Weed Eaters

For safe use and long-term maintenance of the machine, we think you should know these notes when operating the machine:

  • Make sure the product is fully assembled and safe before you start using it.
  • After the engine stops, the bevel gear is still hot and may cause injury. So give it 15 to 20 minutes until the engine cools down.
  • Do not operate the machine in bad weather (rain, strong wind, storm) or unbalanced, slippery positions.
  • Next, you probably already know that you won't use the machine often when the winter starts, so it needs to be carefully cleaned and dried before storing it in your storage.
  • If you regularly use the device, use hearing protection because of the risk of permanent hearing loss. Similarly, for the eyes, you should choose a device to ensure the safety of your eyes.
  • Always carry first aid equipment with you in case of emergency and necessity.
