How to Identify and Fix Common Gardening Problems ?

We provide a variety of viewpoints on how to identify and fix common gardening problems. Our sources include academic articles, blog posts, and personal essays from experienced gardeners :

When the spark arrestor is clogged, the engine can`t get rid of its exhaust gases, and it won`t keep running. The spark arrestor is a screen located just behind the muffler. Pull it out and clean or replace it.
The clutch engages the clutch pads to spin the trimmer head. If the clutch assembly is defective, the clutch will not disengage the clutch pads, and the trimmer head will continue to spin, even at low speeds. If the clutch is defective, replace it. (Note: some string trimmers do not have a clutch.
The most likely culprit is a dirty or clogged air filter. Issues with your fuel pump or fuel filter can also cause your engine to idle then die with any throttle. If you have an older car, it could also be a bad carburetor.
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.
When your trimmer starts and runs on choke, it could be because the check valve in the gas cap is clogged. Start the trimmer and gently unscrew the gas cap halfway off. Turn the choke off and assess. If the engine is still running, that means the gas cap may be the culprit.
Check the Tank Filter

If you can`t see fuel in the priming bulb, there`s a good chance your tank filter is blocking the fuel mix from moving to the engine.

Check for corrosion, breakage, deposits or melted parts. If you notice any of these negative symptoms, it`s time to replace the plug. A filter maintains a clean airflow inside the engine and stops small particles to enter and damage its internal parts. So, an air filter might clog over time.
If the engine is not revving up and cuts out before you reach higher revs then you need to do the following checks: Fuel: Make sure it is fresh and correctly mixed (see `Starting Issues`). Air filter: Make sure it is clean and unclogged. Fuel cap: Make sure it`s hand-tight.

The head won,t turn – Craftsman 25cc Gas Line Trimmer
ANSWER : You will need to pull the head off, as it sounds like the cable is off. there should be four bolts/screws, there maybe some in the middle also, gently remove the head(this is the top of the trimmer where the pull cord is, once you have it separated you can turn the cable by hand and the line feeder should rotate, if it does then look inside the head and make sure it is still square and not rounded. or you can pull the line feeder off and pull the cord and see if the cable rotates, whichever you feel comfortable with trying. Good Luck Tim

My hedge trimmer will not start… Put in new gas
ANSWER : It’s not getting gas, due to being gummed up with old gas. Remove all of the old gas and mix up a batch of fresh gas&oil. Also get some carb cleaner. Put just a little of the gas&oil mix plus an equal part carb cleaner. Try to start it just to work the new mixture through the carb. You might use the spray start to help pull the new gas through. If it fires up on the new gas&oil&carbcleaner mix, shut it off and let it sit for an hour or two. Drain it out and try just a little gas&oiil without the carb cleaner. If all is well fill the tank. If not, repeat the whole process. If you can’t clear the gum this way you may have to remove the carb to clean it.
Good luck.
