Weed trimmers can be problematic to start, and when they start to age they sometimes need a little help by adding a small amount of gas to the cylinder head. Some people use starter fluid for this, but a small amount of gas can be used as described in this article.

Steps

1. 1 Make sure the trimmer gas cylinder is full before starting it if it is not working properly. Perform a quick check to calm yourself.
2. 2 Remove the spark plug with a wrench.
3. 3 Check the rim below the spark plug for carbon build-up. The rim must be silver, not black, also there should be no deposits on it. If the rim is dirty, you need to clean it, scrape off the deposits with a steel brush, or you can use a small flat screwdriver. Be careful not to break the white ceramic insulator.
4. 4 Make sure you are away from any gas first and then heat the spark plug on the rim with a butane lighter.
5. 5 Fill the tip with gas and place it in the chamber, then replace the spark plug and tighten it.
6. 6 Turn on the throttle, press the switch three times, pausing for 4 seconds between each press.
7. 7 Pull the starter rope a couple of times until you hear the engine start. Increase the speed a little, then stop as the throttle is still on.
8. 8 Pull the cable again several times and the engine should start.
   • If the engine does not start, replace the spark plug with a new one, as this may be the problem. (There is a number engraved on the spark plug, so write it down before going to the store.)
9. 9 If the engine still won't start, carbon contamination could be the culprit and you'll need a carburetor cleaner to do this.
10. 10 Clean the carburetor. To clean the carburetor, remove the cap and spray a jet of cleaner over the nozzles, making sure they are clean and free of blockages.
    • Then remove the main plug from the line and spray with cleaner so that they fly into the pipe where the cap was attached and replace the plug.
    • Press the cleaner several times so that it goes straight down the line into the carburetor.
    • Repeat this procedure several times.
11. 11 Check the spark plug flame curtain, which may also be clogged. This curtain prevents hot muffler particles from escaping, which could cause a fire. If it is heavily soiled, remove it and clean it with a wire brush or a piece of wood, then put it back.
12. 12 If the trimmer still won't turn on, it may be clogged and you may need a new carburetor. Also note that after a few drops of gas have been injected into the cylinder and the spark plug is replaced, it may start a little, but not work. If this happens, it may mean that the carburetor is clogged, and therefore the gas does not reach from the carburetor to the cylinder, and the only thing that can be done is to let it run for a while, it may turn out that you have put a little gas in the cylinder. If the trimmer does not work at all, it is usually because the spark plug is either bad or dirty.
13. 13 Always release all gas from the trimmer and all gas-powered equipment after the season. Press down on the bulb several times, causing excess gas to start the carburetor, and then pull on the starter cord several times, forcing all the gas to escape.Excessive gas in the carburetor over the winter will cause a blockage, so always leave it empty and clean when the trimmer is not in use for an extended period.

Tips

• Change the weighted filter in the gas tank in the weed trimmers. These filters can be easily removed with a small hook at the end of the wire hangers. The weighted filter is located along the length of the tube in the gas tank and prevents you from reaching the bottom of the tank no matter how you hold the trimmer. The filter can easily become clogged with all types of debris.
• Today's ethanol gasoline is a big problem for small two-stroke and four-stroke engines, especially engines that are not used every day or even every other day. Ethanol separates and goes to the bottom of the tank. It leaves a resinous residue or "varnish" on parts of the carburetor and fuel line. Some say that today, this is the cause of most minor engine problems. These small carburettors have small fuel lines, needle injectors, curtain filters and vents that can be clogged or partially clogged from the smallest contaminants.
• To prevent this problem in your engines, use gasoline additives, before than to fill any gas reservoirs of a small engine. Some supplements will help prevent problems; some will help delete varnish and resinous secretions. These supplements are inexpensive and non-hazardous.
• Also, discard all old metal cans. They tend to rust on the inside after a year or two, and rust particles will clog filters and nozzles.
