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 :

Remove the spark plug and inspect if it is dirty, cracked, eroded, or damaged. There may also be a heavy carbon buildup or a burned-up electrode. If the spark plug has one or more of these issues, replace it with a new one.
If your chainsaw does not start, the fuel may be too hot. To prevent this from happening, always use fresh fuel and reduce your operating time when the weather is warm. If your chainsaw will not start, place it in a cool area away from sunlight for at least 20 minutes.
With a firm grip (i.e. left hand on top handle and foot through rear handle) pull the starter cord 3–4 times, or until you hear the engine `fire`. NOTE: Do not pull starter cord more the 3–4 times while on full choke to avoid engine flooding.
Why Won`t My Car Start? When your engine cranks but won`t start or run, it could mean your engine is having trouble producing a spark, getting fuel, or creating compression. The most common causes are problems in the ignition (for example, a bad ignition coil) or fuel system (for example, a clogged fuel filter).
One tell-tale sign that a chainsaw has flooded is the smell of fresh petrol near the muffler. To ascertain whether this is indeed the problem, simply disassemble the part, pull the starter cord as if you were switching on the engine, then dry it, reassemble it and try switching it on again.
And finally, the chainsaw giving off smoke is a surefire sign of it being overheated. I`m not talking about exhaust smoke, but smoke with “unnatural” color and intensity. And finally, if your chainsaw stops after displaying one or more of the above signs – you can be about 90% sure that it overheated.
Remove the spark plug, dry it, crank over the engine a few times to dry the cylinder. Now refit the plug and try again. Set the switch to “On”, set throttle to fully open, set choke to “Off” and crank over the engine. Expect the saw to start on the second or 3rd pull.
Many chainsaw models can be started in what is known as `half-throttle` position. In this position, the chain can rotate – if the chain brake is not activated. There are two safe positions to start your chainsaw: on the ground, or with the saw between your legs.
Even if your saw is in ideal working order, it will overheat if you overwork it. Two ways to do that are to operate it with a dull chain and try to make it do something for which it isn`t designed, such as cut a curve.
One of the first symptoms of a problem with the ignition module are engine performance issues. If the ignition module fails or has any problems it can lead to performance issues with the vehicle, such as misfires, hesitation, loss of power, and even reduced fuel economy.
A good spark will be blue-white and will be plainly visible in daylight. If a good spark is present, the problem is probably not in the ignition system. Check the fuel system and/or stark timing. Weak sparks are orange or red and may be hard to see in daylight.
Bad Sensors

One common culprit for this problem is the crankshaft position sensor, which measures the position and speed of the crankshaft. The computer uses the information from this sensor to know when to fire the spark plugs. If the sensor isn`t working, the spark plugs won`t fire, keeping the engine from starting.

One tell-tale sign that a chainsaw has flooded is the smell of fresh petrol near the muffler. To ascertain whether this is indeed the problem, simply disassemble the part, pull the starter cord as if you were switching on the engine, then dry it, reassemble it and try switching it on again.
Many people wonder if a flooded chainsaw will fix itself? The answer is yes, but not always. By letting the chainsaw sit for about 20 minutes it will allow some of the fuel inside the engine to evaporate.
