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 :

If you`ve used the correct procedure to start your Stihl trimmer and it does not start, the problem is likely related to either the spark, the fuel or the air circulation in the combustion chamber. More often than not, it`s an easy fix, possibly involving replacement of a spark plug or air filter.
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.
Make sure the throttle cable is seated properly inside the handle and rejoin the two halves of the handle back together. The spring returns the trigger back to its normal position once you take your finger off. If the trigger does not return, your spring is broken and needs to be replaced.
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.

If no spark appears, check for broken wires, shorts, grounds or a defective stop switch. Once you have confirmed that the stop switch is working, reconnect the spark plug lead.
If there isn`t any spark visible when kicking the engine over, follow these steps: (1) Check the metal cap on top of the spark plug and make sure it is tight. Give it a gentle twist with a pair of pliers if it isn`t. (2) Make sure that the spark plug lead wire is solidly connected to the spark plug 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 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 more worn or dirty spark plugs are, the greater the pull on the rewind and more effort is required to produce an adequate spark. If you haven`t turned on your engine recently, your mower won`t start and/or you have to tug repeatedly on the rewind to start the engine, a damaged spark plug may be the culprit.

If your STIHL chainsaw is going to have a problem, it`s likely to be with a worn carburetor, bad spark plugs, loose fuel hoses, or clogged fuel lines. You should also inspect the fuel intake system and ensure that there are no compression issues.
