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 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.
A spark plug might be defective and needs to be replaced.

If your chainsaw has a defective spark plug, it cannot create an electrical current to ignite the system. 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.

Check to see if the switch and terminals are free from rust and replace any damaged or broken spark plugs wires as necessary. Alternatively, it could be a bad ignition module. A simple way of testing the ignition module is to leave the car idling for 30 minutes and then tap the ignition module with a screwdriver.
If the ignition coil does not have spark, it`s time to check its wires. Use a test light to check the continuity on the signal wire and power wire on the ignition coil. If both wires are functional but the coil fails to produce spark, the ignition coil or the ignition control module is bad.
When the high voltage produced by the ignition system is applied between the center electrode and ground electrode of the spark plug, the insulation between the electrodes breaks down, current flows in the discharge phenomenon, and an electrical spark is generated.
If you have an electric chainsaw that won`t start, first make sure that the power cable is connected to the mains, then check whether the cable and plug are damaged. If they aren`t, the problem could lie in the motor which, for example, may have worn or damaged brushes.
Many factors can cause a spark plug to fail; from incorrect heat ranges to improper gapping, to chemical contamination. Yet 90% of spark plug damage claims are due to improper torque. Proper installation torque is critical in the plug`s ability to dissipate heat out of the combustion chamber and into the cylinder head.
