The carburetor is a device that’s responsible for delivering the right ratio of fuel and air to your weed eater. If it becomes clogged, it won’t be able to do its job and your weed eater will not run properly.
To diagnose if this is your carb is the problem we recommend first cleaning out the carburetor with a carburetor cleaner. If you don’t have any on hand, a mixture of gas and oil can also work in a pinch.
Our favorite carburetor cleaner is the Gumout Carb and Choke Cleaner. Gumout is great because it helps fix problems like stalling, difficulty starting and emissions problems. It works by removing deposits from the inside and outside of the carb. We like it because it is super affordable and a single can will last for multiple years.
Once the carburetor is cleaned, you should restart your weed eater and see if this problem has been fixed. Another thing to note is that some weed eater models may require a new fuel filter to help keep the carburetor clean, so be sure to check that too.
Air Leak in Fuel Line
An air leak in your fuel line can also affect your weed eater’s performance. This happens when the line is cracked or there’s a hole in it, allowing air to mix with fuel and make the engine too lean.
To determine if this is a problem you are experiencing, inspect all of your fuel lines for any signs of damage or cracks.
If you find a broken line, it’s best to replace it with a new one. If you’re unable to find a hole or crack, try using compressed air and blowing into the fuel line near the carburetor until you hear air coming out.
Clogged Air Filter or Fuel Filter
Another common problem is a clogged air filter or fuel filter. A clogged air filter will prevent fresh air from entering your engine, resulting in a lack of power and the weed eater dying when you give it gas.
To diagnose if this is your issue, remove the air filter from the weed eater and inspect it for any dirt or debris that may be clogging it. If there is some build-up, simply clean the filter using some warm water. If the filter is too dirty or damaged you may have to replace it.

If the weed eater has been sitting in the shed for a while, then it’s possible that the fuel has gone bad. Old gasoline can cause your engine to run improperly, resulting in the weed eater dying when you give it gas.
To test for this, try draining all of the old gasoline from the tank and refill with fresh fuel. If this doesn’t help then you may need to clean out or replace the carburetor before getting your weed eater working properly again. Sometimes loosening the gas cap can help reset the flow of gasoline in a gas weed eater.
Lack of Oil
Gas engine use oil to lubricate all of their moving parts, and if there’s not enough oil in the system then it can cause major damage to the engine. If your weed eater has run out of oil, then this could be why it dies when you give it gas.
To check for this, open up the weed eater’s tank and inspect the amount of oil. If the tank is empty, then you will need to refill it with fresh oil before restarting the engine.
The primer is responsible for getting the fuel and air inside of the engine, so if it’s not working correctly then your weed eater won’t run at full speed but might start for a short time due to gas already inside the engine.
To diagnose this, you will need to inspect the primer for any signs of damage or wear and tear. If everything looks good but it still isn’t working properly, try replacing the primer with a new one so that the engine gets enough gas while starting up.
Not Enough Power
If you are using an electric weed eater the problem might be with the power supply. Make sure that the outlet you are using is providing enough power for the weed eater or the battery is fully charged if it is a battery powered weed eater.
Some extension cords will not provide enough power for the weed eater to start up and run properly, so make sure you are using an appropriate cord that is not too long or made of low-grade material.
Finally, inspect your battery connections if you have a battery powered weed eater as this could be preventing it from getting the necessary power to start up. Clean off any grass that might be blocking the connection and try again.
Exhaust can also be a common problem for weed eaters, especially two-cycle engines. If your exhaust is clogged or blocked, it can prevent the engine from getting enough air to run properly and will eventually cause the gas trimmer to stall due to the motor choking on the exhaust.
This problem can be fixed by removing the exhaust and inspecting it for any signs of blockage. If the exhaust is clogged, you will have to clean it out before re-installing it.
