Getting quality weed wacker is vital if you want a meticulously trimmed lawn.
However, you should also be ready to face the challenges that come with using a weed wacker.
Regardless of whether the weed wacker is of high-quality or not, it may bog down because of different reasons.
Hence, as you use your weed eater to cut grass, make sure that you know some of the signs of a bogged down weed wacker.
If your weed wacker stops working abruptly, you should not rush it to a mechanic.
Instead, you should examine it and find out what the problem is. Most weed wacker problems are DIY and straightforward to fix.
For instance, your machine might stall because it is switched off, lack of fuel, disconnected extension cord, or damaged gasket.
In this post, we’re going to highlight some of the causes of a weed wacker bogging down and how to fix them. Let’s get started!
1. Fuel Problems
One of the common problems that might cause your string trimmer to bog down is insufficient fuel. This applies to gasoline-powered weed wacker and not electric-powered weed wacker.
To find out whether it’s the lack of fuel causing your machine to bog down, check the level of fuel in the tank.
It is essential always to check and ensure that you have enough fuel before cutting grass.
Apart from having insufficient fuel, using old fuel can cause the machine to bog down as well.
This is because such fuel moves unstably via the engine’s carburetor and prevents it from starting.
Another scenario where the weed eater may fail to run is when the engine is over-flooded with fuel. In such a case, you will have to get rid of the excess fuel for the weed wacker to run smoothly.
If you check and find that you’ve enough fuel, the next step is to inspect the fuel tubes.
At times, the fuel tubes may be damaged or disconnected, which may prohibit the engine from getting the much-needed energy for smooth operation.
When filling fuel in your machine, ensure that gasoline and oil are properly mixed as this can also cause the weed whacker to bog down.
As we’ve explained, all of the fuel problems that cause the machine to bog down can be handled with a lot of ease.
So, you don’t need to acquire the services of a professional to get your machine running again.
2. Electrical Problems
If you have an electrical-powered weed eater, you may face one of these problems. However, electrical issues don’t apply to gasoline-powered weed whackers.
The most usual electrical problem is a poorly connected extension cord.
If your weed wacker is not running or stops abruptly, then you should check whether it is plugged in properly.
To prevent frequent disconnection, it is recommended that you purchase a quality extension cord.
Another problem maybe with the fuse or circuit breaker where the machine is connected.
Check this before you make any other conclusion.
Additionally, you need to select a weed wacker with a slightly long extension cord.
This will prevent you from stretching it and changing it from one electrical outlet to another.
3. Engine Problems
The engine is the central part of the weed wacker. For this reason, there are a variety of issues that can cause the engine to fail.
Some of them include the spoiled electrical system, low fuel level, and a dirty filter.
Finding out which part of the engine has a problem is quite challenging.
Therefore, you may need a professional, or you can turn on the engine and try to figure out the problem.
If your engine has low fuel, then you can add fuel.
But if it has a spoiled electrical system, then you will need a professional to handle it. Don’t take the risk as you may cause further damage.
4. Spark Plugs Problems
It is easier to detect a spark plug problem, unlike other weed wacker problems that we’ve looked at.
If you’ve got a spark plug issue, the engine won’t respond at all or even produce a sound.
This is usually caused by a dirty spark plug.
A dirty spark plug will fail to fire and start the air/fuel mixture that starts the engine. This is also known as misfiring.
Additionally, you can know if your weed eater spark plug is bad when it starts hard.
At first, you may think that it is because of the low fuel, but even after adding fuel, the issue may persist.
If you have a dirty or fouled spark plug, you should clean it and see if it works.
If it doesn’t work, simply replace it with a brand new spark plug.
5. Carb Problems
A dirty carburetor can also cause issues for your weed wacker.
Since fuel lines, gasket, and air filters are connected to the carburetor, you need to ensure that it is clean and functioning well.
Also, if the string trimmer is not used for long, it is bound to fail to start.
If that’s the case, then you should buy a new carburetor and replace the old or outdated one.
A damaged carburetor may also cause the engine to choke or run rough. To get your carburetor working again, you should repair or replace it with a new one.
6. Damaged Gasket
A weed wacker’s gasket helps to seal parts; thus, sealing off air and fluids from going into places they are not allowed to.
As a result, if the gasket is damaged, it will pull excess air into the engine, which will lead to an improper fuel/air mixture.
When this happens, there will be a loss in power, and the weed wacker will bog down.
To know if the string trimmer’ gasket is damaged, you will have to disassemble the air filter and fuel line.
Afterward, you can check the state of the gasket.
If there is a leakage or tear, you will have to clean it and replace it with a new one.
Unlike other parts that can be repaired, a gasket can only be used once. So, if it tears or gets damaged, then your only option is to buy a new one.
7. Air Filter Problems
The air filter can also cause your string trimmer to bog down. However, this part is easier to fix, and you don’t need professional help.
The weed wacker’s air filter may make the machine to bog down due to excessive air being let into the engine or due to dirt.
Excessive air usually enters the engine if the air filter is left wide open. At first, it will make the engine to choke and then stall.
On the other hand, a dirty air filter may become clogged and hinder the flow of air to the engine.
If you face one of the above challenges, then you will have to install the air filter properly. But if the problem persists, then you will have to replace the old air filter with a new one.
8. Improperly Set Screws
If you have inspected all the other parts that we have discussed and your weed wacker isn’t starting, then you should check the screws.
The weed wacker comes typically with low and high screws.
When these screws are poorly installed, your machine is bound to have issues such as bogging down.
Therefore, you have to examine them and ensure that they are in the right position.
The best way to install the screws in position is by adjusting them in opposite directions.
After setting them, you can try turning on the weed eater and see if it works properly.
It is important to follow the manufacturer’s manual to avoid such issues. And if you’re not sure of how to install the screws, get professional assistance.
9. Wrong Gas/Oil Mixture
For those using a gasoline weed wacker, it is essential to mix the right gas and oil ratios.
Some people mix a lot of gas with little oil. That’s wrong and may cause the weed wacker to stall.
Instead, you should ensure that you follow the manufacturer’s recommended ratios.
Most manuals recommend mixing 50:1, while others 32:1. If you mix the gas and oil well, there you will have nothing to worry about.
A weed wacker is a vital tool for those individuals who want to keep their lawns lush and beautiful.
However, like any other tool, it develops problems after some time of use. For this reason, it is crucial always to ensure your weed wacker is in top form.
That’s why you need to go for the best weed wacker with a proven track record.
