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 :

A clogged carburetor is most commonly caused by leaving fuel in the hedge trimmer for a long period of time. Over time, some of the ingredients in the fuel may evaporate, leaving behind a thicker, stickier substance. This sticky fuel can clog up the carburetor and cause the engine to stall or run roughly.
The choke lever has two settings: a downward diagonal line (if the engine is cold and hasn`t yet been used that day) and a vertical line (if the engine is warm or if the engine has been running).
Hedge trimmer blades can be sharpened by hand, and it is recommended that you do so regularly: the job needs a flat file, a whetstone and a little careful attention. Alternatively, your STIHL dealer can sharpen the blades perfectly for you.
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.
Pulling the choke lever provides proper fuel-starting mixture when the engine is cold. When attempting to start a cold engine, pull the choke lever outward to close. Slowly return the choke to the open position as the engine warms. Leave the choke in the OFF/OPEN position when starting or restarting a warm engine.
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.
STIHL saw chains are generally filed to an angle of 30° – parallel to the service mark for the filing angle. Hold the file so that one quarter of its diameter projects above the top plate.
The recommended sharpening angle is at 30-degrees. Be sure to sharpen both sides of the blade evenly at the right cutting angle. Wipe off any debris from the sharp blades with a clean cloth before reattaching it to the hedge trimmer.
Ideally, sharpening should be done before the blades show too many visible signs of wear, we recommend sharpening every 50 hours of use or so, this is to ensure consistent cutting performance and to enable you to enjoy your Hedge Trimmer for as long as possible.
Just Like Spark 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 gases from flowing out, which leads to power loss or not running at all.
They are typically labeled L (low speed jet), H (high speed jet), and I (idler jet).
Choke: 1. A control on a carburetor to adjust the air/fuel mixture when the engine is cold. Throttle: 1. A valve that regulates the supply of fuel-air mixture to an internal combustion engine and thus controls its speed; a similar valve that controls the air supply to an engine.
The first thing to do is to ensure that the battery is fully charged. If after charging the battery you are still experiencing the problem, then it may indicate a fault with either the battery or charger. The defective item will need to be replaced.
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.
