If your Husqvarna weed eater won’t stay running, it has a problem with either carb kit or coil of the engine. There are several other minors yet important factors/parts that may cause your weed eater to shut down. To provide the utmost service in your outdoor activities, Husqvarna has been contributing remarkably. But, sometimes their products produce unwanted discrepancies that don’t go with their name.
A weed eater is a handy tool that helps you cut through and maintain your backyard like a pro. But, the tool can be frustrating if it produces operational hazards or denies to operate at all. To get the optimum output from your weed eater, make sure that you are taking enough care of your trimmer.
Unfortunately, even after following all the maintenance rules, your weed eater may die within seconds of start-ups. The same issue may come out even from a new/intake machine. Anyway, whatever be the state of your machine, let’s find out some probable reasons along with their solutions.
Troubleshooting: Husqvarna Weed Eater Won’t Stay Running
Before you move on to troubleshoot your weed eater, let us ask you a few simple questions. How long have you been using your weed eater? What was the price of the string trimmer? You don’t want to waste your money and time something that doesn’t worth it, do you? Why these questions when you are here to learn the troubleshooting process? Well:
- If your weed wacker is 5 years or older, why should you invest money on this lad that won’t produce the expected output anymore? Consider replacing it with a new one.
- We have been experiencing that, some string trimmer owners invest $70 in repairing a trimmer that cost them below $100 at the time of buying!! So? Make sure that you are not doing the same mistakes here. Even if you replace more than 90% parts of your weed wacker, it won’t be powerful and young anymore!
Note: We have enlisted the probable reasons along with their troubleshooting in an easy to difficult sequence. We recommend you to just try the basic level troubleshooting that won’t cost that much money and time. If you fail to fix following the steps, go to a local expert or buy a new trimmer.
Problem with Fuel & Oil-mixing
Generally, we don’t use our trimmer frequently as the grass doesn’t grow overnight. So, there remains the scope that the fuel in the engine is 2 to 3 months old. Here, the fuel will cause the engine stall or shut down as the fuel becomes worse with time. Any fuel that is beyond an 8-week old is normally bad. So, first of all, make sure that you are not using any bad fuel.
Again, the fuel issue comes into play once you try to use the trimmer for the first time after unpacking from winter storage. During the winter, the fuel got sticky and now making trouble to run the engine smoothly. The gum/lubricating quality of the fuel becomes problematic after expiry!
Now, come to the oil-fuel mixture issue. The manufacturer recommends an initial 32-1 fuel-oil mixture ratio for up to 3-4 tanks. But, if you do not read the user manual or neglect to abide by it, you may get the output. Moreover, if your weed eater is an older one but produces the problem, you should try using the 32-1 ratio mixture for a few minutes to observe.
Problem with the Spark Plug
The spark plug has a very crucial role to run your engine. It supplies the required spark to burn the fuel in the combustion chamber. When the spark plug becomes exhausted or fails to supply sufficient spark, your weed eater has no way to stay alive. So, you need to inspect, clean, and if required replace it to make it serviceable. Otherwise, you cannot be able to run your string trimmer irrespective of the rectifications you made. It would be better if you change your current spark plug with a resistor plug. Resistor plug works better than a spark plug in every sense.
Problem with Gas/Air Filter
The gas filter of a weed eater ensures that the engine gets the purest gas to run. On the other hand, the air filter ensures, the combustion chamber gets sufficient and cleaned air to burn the gas/fuel. So, see the great roles they are to paly to run your weed wacker. So, you have to inspect and make sure that these filters are in working condition.
Take out the gas and air filter. At first clean them applying air blow and then applying alcohol/kerosene. Check the fuel priming bulb to identify any crack or leak. The bulb may be letting air into the fuel that’s causing the engine to shut down. Change the faulty priming bulb with a new one. Moreover, If you think one or both of these filters need to be replaced, do it.
Problem with Gas Tank Vent
Gasoline fluctuates with the pressure that results from temperature. It expands in volume during warming up and shrinks as it cools down. To, supply the workable gasoline to the engine, the gas vent has a significant role to play. It works as the ventilator of the gas tank. It steadies the pressure of the gas tank and offers sound quality gas to the engine.
When the gas vent becomes damaged/clogged/ deteriorated, it cannot perform its assigned task. As a result, your engine doesn’t get the workable fuel and doesn’t stay running. So, you need to take out the gas vent and look for any discrepancy that needs to be corrected. Consider replacing the gas vent if required.
Problem with Seals and Gaskets
The Husqvarna weed eater has several seals and gaskets inside and outside the engine. The purpose of using them is to prevent the engine from leaking oil/fuel/pressure and many more. When these seals and gaskets go out of order or become unserviceable with time, your engine may face trouble to run. Watch out for seals and gaskets as many as you can and observe their conditions. If required, consider replacing them with new ones.
Problem with Engine cover, Carb plumbing, and Cylinder
Every part of the trimmer engine has to stick with it at a fixed torque. If, by any means, your engine cover gets loosen or the carb plumbing with small holes, the outcome could be engine stall. Many string trimmers come with a plastic cover attached to the engine. This plastic covers loosen with time and causes the engine to shut down.
Furthermore, the loose cylinder may produce the same result. Sometimes, the loose cylinder head causes the engine to shut down within seconds of starting. So, look for these places/parts of the engine and make sure they are fine. If required, use a star washer to lock the head of the cylinder.
Sometimes, the cover/muffler of the exhaust may cause the problem. Take the muffler off, remove and clean the screen, and then place it to its bay.
Problem with the Carb and Coil Kit
The carburetor of your Husqvarna weed eater has the most important role to play. It takes the gasoline from the gas tank and supplies it to the combustion chambers. It works at a time with the gas tank, combustion chamber, throttle, and spark plug. When you increase/decrease the engine rpm using the throttle, carburetor contacts with the said parts and makes necessary adjustments. Thus, you get an efficient performance from your weed eater. But, if the carb becomes faulty, it cannot do its part and let the engine shut down.
To solve the issue, take out the carb and inspect for any clogging/blockage. After that clean, it using kerosene and install it. If the carb goes out of working condition, you have to change it without and delay.
Another important part of the trimmer engine is its coil. The coil is the ultimate portion of the engine that makes the engine revolve. So, any deteriorated coil will result in shutting down the engine. No correction can be made to fix the coil other than buying a new one.
Generally, Husqvarna gas weed eater doesn’t produce many hassles. But, we cannot deny that there is no perfect machine available on the market that doesn’t offer trouble. So, we need to be careful about the scheduled maintenance of our weed wacker to get the best out of it. On the other hand, we should not spend much money to repair our string trimmer as they do not worth it.
