If it starts and runs for a couple seconds and dies then yea, most likely it is the carburetor. If it runs for longer than that it will be something else

If your trimmer engine idles, but stalls on throttle, check the following parts: the gasket, primer bulb, fuel filter, air filter, fuel vent, fuel line, and carburetor. The repair and symptom guide will help you better identify the part needed to be replaced and how.
Sometimes a weed eater will start, and even idle just fine, but when you give it gas, it dies. This is often a sign that the engine is struggling to get sufficient amounts of either fuel or air. When it comes to gas-powered weed eaters, the problem often lies with the quality and flow of fuel.
As with plug fouling, too much oil in the gasoline, inferior oil, a dirty air filter and/or continued operation at less than full throttle will plug the screen with carbon deposits. This prevents exhaust gas flow, which leads to power loss.
So, an air filter might clog over time. Once blocked with dust and debris, it cannot supply the required amount of oxygen to your trimmer` engine resulting in power loss. Find the air filter, take out this component, clean and reassemble it. Replace the part if you cannot reuse it.
As with plug fouling, too much oil in the gasoline, inferior oil and continued low-rpm operation can plug the screen with carbon deposits. This prevents exhaust-gas flow, which leads to power loss. In extreme cases, heavy deposits choke airflow enough to leave you with a weed eater that won`t start.
Checking the Fuel Mix
The most common problem with a strimmer not starting is that there`s a problem with the fuel mix. Double check that you`ve used 40 parts fresh unleaded petrol to 1 part 2-stroke oil (40:1). Check the petrol you`ve used isn`t stale.
Turn on the ignition switch and pull the starting cord quickly. You should see a spark in the plug gap. Since the spark may be faint, it may help to do the test in a dark area. If there is no spark, check for a broken or shorted (bare) lead wire or bad switch.

My weed eater hedge trimmer runs for about 10 minutes and cuts off. It seems as though it is flooded, because it won’t start again until some time later. But it continues with the same pattern. I purchased a can of premixed gas/oil to make sure it was my mixture, to no avail. I have not replaced the spark plug yet, but I don’t think that has anything to do with it. Do you have any suggestions?
The plug can be the problem but also the air mix as well get the best plug you can
I have been using my weed eater all season with no problems. Last week it was harder to start then normal and would die when I applied the gas. It would start back up after a few tries and them doo the same thing.
Try getting some fresh gas and 2 cycle oil mix. Mix up a fresh batch and see how that works for you..When I say fresh I mean from the gas station not from the can in the garage.Good Day.
Weed eater starts but won’t stay running
Just bought a new Poulan 25cc 2cycle gas power weed eater . I can start it with the choke on but as soon as put on run it dies.
STRING KEEPS BREAKING ON A TROY BILT WEED EATER TB539E
Take a look at the hole in the spool where the business end of the string comes through. There should be a smooth metal grommet or smooth short tube there. If the metal is missing, then the string is breaking because it rubs against plastic and heats up very quickly. Or the tube or grommet might have a rough or sharp spot. You might be able to polish it up with a Dremmel type of tool.

Weed eater won’t run
Sounds like you may just have a dirty carburetor.Youwill need to disassemble the carburetor and spray with carb.cleaner.Make sure the small screen is free of debris. (Should be able to seedaylight through it.)Use a Den Tek Brush, (http://www.drugstore.com/products/prod.asp?pid=165357&catid=1152),to clean the small portals in carb. These portals can become blocked. Reassemble and start.If the carb. parts are more than 4 years old, you may have to replace them.If you need further assistance, just let me know.Jim

Starts right up on choke. then run inrun position for a minute and have to go back to choke to keep it running ,then it runs fine for a couple of minutes and have to go back to choke and start all over again.
This happens with the cover off, so not the filter.
