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 :

The air filter or exhaust port may be blocked. The trimmer may need lubrication and cooling fins or air passages may be blocked. A cordless trimmer`s battery or charger may be faulty.
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.
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.
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.
A dirty spark plug

If the central electrode is covered in dirt this can short out the spark so that it won`t jump to the outer electrode, which will mean you will struggle to start the whipper snipper – you can clean the dirt off with a tooth brush, or small wire brush.

The trimmer can sputter and stall if it isn`t getting enough fuel, and that can happen simply because the fuel filter is dirty. Fuel filters are inexpensive, and it`s more practical to replace a dirty one than it is to try to clean it. On most models, it`s in the gas tank or on the cap.
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.
If you realise that your mix isn`t right, the best thing is to stop your machine and drain the fuel. Mix some fuel that is at the correct ratio, clean any air filters and make good. If it is an incorrect mixture over a prolonged time then it`s not good news.
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.

The Cutting-Line Head Won`t Stop Turning

The common causes of this problem include an excessive idle speed, a faulty throttle cable, or a clutch that has become excessively worn or damaged due to frequent trimmer use.

Does it use a fuel and oil mixture?You probably did that.

Try removing the spark plug and cleaning it with a wire brush or some emery cloth.Make sure you have spark by connecting the plug wire and resting the plug on the metal motor block.

Do not hold the plug in your hand ,if you have no spark you may have a bad magneto.
