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 :

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.
The air filter may be clogged. If the air filter is clogged, the engine will get too much fuel and not enough air. As a result, the engine may not start. If the air filter is clogged, replace it.
If the drive shaft is broken, the string trimmer head won`t spin. The drive shaft is not repairable—if the drive shaft is broken, you must replace it. Need help finding your model number? If the threads on the drive shaft are stripped, the trimmer head will not stay on the shaft.
Measure and adjust the gap (as necessary) to twenty-six thousandths of an inch. (0.026). INSTALLING THE NEW SPARK PLUG [top] 3. Install the new spark plug.
Loss of spark is caused by anything that prevents coil voltage from jumping the electrode gap at the end of the spark plug. This includes worn, fouled or damaged spark plugs, bad plug wires or a cracked distributor cap.
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.
Loose, Dirty or Disconnected Spark Plug in Your Lawn Mower: Check it out, clean off debris, re-connect and tighten. Dirty Air Filter: Clean or replace. Fuel Not Reaching the Engine: Tap the side of the carburetor to help the flow of gas. If this doesn`t work, you might need a new fuel filter.
Over time, the spark arrestor can become clogged with soot. If the spark arrestor is clogged, the edger may stall or run roughly. To unclog the spark arrestor, remove it and clean it with a wire brush. You can also replace the spark arrestor.
As a general rule, you should change the spark plug approximately every 100 hours. This may vary across brands and specific models. Check your Owner`s Manual for specific information on how often to change the spark plug and the proper gap setting. Check the grease/oil in the cutting head gearbox often.
Failing spark plugs can cause the car engine to misfire and thus affect its performance. A single spark plug that fails to ignite the fuel-air mixture can cause a halt in the running of the engine. It can result in incomplete combustion and damage to the catalytic converter of the car.
The most common reasons a Chevrolet Spark won`t start are a dead battery, an alternator problem, or failed starter.
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.
