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 :

The most common signs of bad spark plugs include start-up trouble, rough idling, sluggish acceleration, declining fuel economy, engine misfiring, and engine knocking.
Common causes include a dirty air filter, spark plug, and carburetor. To fix these issues, replace the fuel filter, clean the carburetor and spark plug, and replace the fuel if it is old as illustrated below.
Faulty spark plugs result in an engine misfire due to incomplete burning fuel. An interrupted combustion process can significantly affect the engine performance. Unattended engine misfire may result in intermittent strange engine sounds, power loss, and engine knock.
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.
Old, worn out spark plugs have a harder time creating the spark that actually powers your engine. If your car stalls when you are trying to turn it on, there could be a problem with spark plugs or damaged spark plug wires. The battery is most likely the culprit if your car has no power and won`t start at all.
Just as importantly, John Deere recommends you change your spark plugs every 100 hours or once a mowing season.
FACT #4: YOU SHOULD CHANGE SPARK PLUGS EVERY 100K MILES OR SO. So, if good spark plugs are the key to avoiding these issues, how long do spark plugs last, exactly? The general rule of thumb about how often to change spark plugs is that they should be replaced after about 100,000 miles of driving.
To remove old spark plugs, you need a socket wrench that can twist the spark plugs inside the engine. An old plug can be tricky to get out sometimes, so you need an extension for your spark plug socket. A standard 5/8″ or 13/16″ socket wrench works for most old spark plugs.

Driving With Faulty Spark Plugs

Malfunctioning spark plugs cause engine problems including, misfires, hard starts, reduced gas mileage, rough idling, and lack of acceleration. Driving with a faulty spark plug will be difficult because the engine might fail to function.

Spark plugs are designed for long-term durability, meaning that they only need to be replaced between every 80,000 and 100,000 miles. However, they can become damaged earlier than expected and require replacements to avoid pricey engine repairs.

Spake plug is not spakeing – John Deere Original 130 160 165 175 180 185 Operators
ANSWER : Hi Lloyd
Make sure you are getting spark at the spark plug, to do this:Remove your spark plug and check to be sure you are getting a bright blue spark at the spark plug.You do this by grounding the plug on the head of the engine and cranking the engine or by pulling the crank rope…watching the plug for spark.If you are getting a nice blue spark then skip A below and go to B.
A…If you do not get a nice blue spark then you may need to replace the electronic module.Note: If you have to replace the module be sure to measure the position it is in, it is critical to starting.The clearance can be measured with a “business card”…use the card for the right clearance between the coil and the flywheel.Take a picture for later reassembly.
B…Also take some fine grit sandpaper (not emery) and lightly sand the flywheel where the magnet is located to clean any rust or corrosion from the magnet area.Please rate meBud
