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 the engine will not crank, you likely have a problem with… Discharged / defective battery or faulty electrical connections. To address these issues, check the battery and charging system for problems. Faulty parts: potentially the safety interlocks, starter motor switch (open circuit) or solenoid.
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.
The fuse block location may vary with the age and style of the mower, but is generally located along the wiring harness between the battery and the key switch. On our current style riding mowers, the fuse will either be: A) Under the hood, behind the steering dash panel.
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 run roughly. If the carburetor is clogged, try cleaning it with carburetor cleaner.
Clip one end of a spark tester to the ignition cable and ground other end to the cylinder head. Spin the flywheel rapidly (at least 350 RPM) and watch for a spark in the tester window. If there`s no spark the coil will need replaced.

Hi there, quick question, there is a black and grey wire on the 13.5hp briggs and stratton, i am unsure which is the earth and which is the power?
ANSWER : The grey one should get power when the key is turned on. This opens the solenoid valve on the carb and lets fuel in. The black one should get earthed when the key is turned off, this shorts out the coil and stops the spark. Aussie Steve.
