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 :

Check/clean/tighten all connections on battery/solenoid/starter/Ignition switch and neg(-) cable to frame or motor. Check to ensure all safety features are working properly and not engaged. Check for an inline fuse, bypass solenoid to see if engine cranks if it does replace solenoid, if no crank replace starter.
When you hear a click as you turn the key, a weak battery, bad starter solenoid, faulty wiring, failed starter motor or a seized engine could be the cause.
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 most common cause for the engine not turning over is simply the battery. Either the battery itself is dead, the terminals are corroded so the current can`t travel through them, or the battery cables themselves are damaged. Inspect your battery terminals and cables, and test the battery.
If a mower is hard to start, it may be the result of a dirty carburetor and/or a clogged air filter. Use a screwdriver to remove the carburetor and clean any dirt out of it with a rag. Clean the air filter or replace it if it`s disposable.
Use Carburetor Cleaner

Fortunately, you can generally do this without even taking the carburetor out of the engine. Start by purchasing some commercial lawnmower carburetor cleanerOpens a new window, which comes in a simple spray can and will make it easy to clean the inside and outside of the carb.

If nothing happens when you turn the ignition key to the “Start” position, it means that the starter motor doesn`t turn over the engine. Most commonly this could be caused by a low battery; read above How to check the battery.
If your vehicle won`t start, it`s usually caused by a dying or dead battery, loose or corroded connection cables, a bad alternator or an issue with the starter. It can be hard to determine if you`re dealing with a battery or an alternator problem.
If you have an older car, it is possible that your key is worn out. It`s the most common reason why car keys do not turn in the ignition. The pins inside the cylinder will not drop correctly, stopping you from starting the car successfully. If you have a spare key available, use it first.

I then primed the mower it started then quit and now it will not start at all. Does anyone have any suggestions of what to do. Thanks

Lawn mower cranck but wont start…
ANSWER : Since you already checked for spark and air I would drain all the fuel out of it and check that fuel for water. Over time some lawn mowers end up with contaminated fuel. You can see the water sitting on the bottom of the fuel if you let it stand for a bit in a small plastic bowl.

Be sure to empty and dry out you fuel can as well. Especially if the mower stopped running right after a refuel. Which is a good sign your gas can is contaminated too.

My Z5426 won’t start. When I pull out the choke and turn the key, gas starts leaking out of the exhaust system just before it gets to the muffler. Last time it did start, it ran really rough. So, I turn off the engine and then tried to restart and that’s when I noticed the fuel leak.
ANSWER : Maybe bad fuel, fuel line leaking, flooding of the carburetor, since it did start and ran rough I am assuming that the gas was left set and more then likely this gummed up the carburetor, you will have to clean/rebuild it. If you have a can of carburetor clean you may be able to spray that into there and clean it up, I would not choke it to start it as it sounds like it got/is flooded/ing. Good Luck Tim
