Overheating is a common issue with almost any machine that uses gas. Weed eaters are no different. They also have issues with overheating. In this section, we’ll discuss common reasons for a weed eater overheating.
Why Is My Weed Eater Overheating?
There are many reasons why your weed eater could be overheating. The most common reason is that the cooling system is clogged. This system allows the motor to cool down, but if it’s blocked, the motor will overheat.
Another reason could be a dirty air passage. If you don’t clean and maintain your weed eater regularly, you can expect some overheating issues to occur over time. So don’t continue to use an overheating weed eater.
How Hot Can My Weed Eater Run?
Every manufacturer has different temperature parameters for their weed eaters. But, in most cases, you would be able to feel it as soon as your weed eater starts to overheat because it’s a lot warmer than what you’re used to.
The most important thing is immediately to switch off your weed eater when you notice an overheating problem. Overheating can cause permanent and irreparable damage to your weed eater.
Why Did My Weed Eater Stop Working?
In most cases, a weed eater stops working due to an improper cleaning or maintenance routine. For example, if your air passage has a build-up of dirt, or if your cooling fins have weeds clogged inside, it could break the weed eater.
Many other reasons could explain why your weed eater stopped working, most of which could be resolved with frequent cleaning. For example, if you have a 2-stroke gas engine, you might have used the wrong ratio to mix oil and gas.

Why Does My Weed Eater Only Run On Half Choke?
A weed eater only runs on half choke when the airflow is restricted. In most cases, this happens when dirt or debris is clogged in the carburettor. Additionally, the motor on a weed eater is not very big, so any small clog could be a problem.
Before scraping the weed eater in frustration, recheck your whole engine and focus on the air filters. If you notice clogged air filters or clumps of weed in the carburetor, it is relatively easy to clean it out and restart your weed eater.
What Happens if a Two-Stroke Weed Eater Overheats?
When a two-stroke weed eater overheats, it will only run on half choke. The most common reasons for overheating two-stroke weed eaters are insufficient air intake, poor lubrication, or a clogged cooling system.
Sometimes you can fix the problem yourself, but other times you would need a professional, like a mechanic, to look at your weed eater. The first step would be to identify what is causing your two-stroke weed eater to overheat and assess whether it is something that you can solve.

What you should check first when your weed eater overheats:
- Check the cooling fins for clumps of weeds or grass. Clear the clumps and clean the cooling system with water and soap. Make sure to rinse out the soap when finished.
- Your carburettor needs to be adjusted. If you use a gas weed eater, your carburettor may need to be adjusted at some point to prevent too much fuel from being fed to the engine.
- If you have a 2-stroke weed eater, use the right ratio for the gas and oil mixture. This will be indicated in your user manual.
- You also need to make sure that the air filter of a gas weed eater is clean. This is where cold air flows into the engine. It is crucial they’re not blocked.
- Battery-operated weed eaters are not designed to work on large and tough terrain. In addition, they are quite weak and will easily overheat from overworking them.
- Using an electric weed eater, you should check the voltage supply. Using a voltage supply that is too high will cause your weed eater to overheat.

Are Gas or Battery Weed Eaters Better?
A gas weed eater would be better for a large property or commercial use. Although for a small property, a battery weed eater would be better. Even though both do the same job, gas weed eaters are generally more powerful.
