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 :

Electric lawnmowers may cut out for two main reasons: A faulty power switch or a loose cable connection. An overheating motor can cause the thermal cut out to trip.
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.
A clogged carburetor is most commonly caused by leaving fuel in the lawn mower for a long period of time. 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 stall.
A dirty carburetor is the most common cause of a lawn mower that starts and then dies. Other possible causes include: Stale/Dirty Gas. Faulty Choke.
Your lawn mower runs for 30 minutes then dies if you are having issues such as a bad spark plug, air problems, a malfunctioning carburetor, or a faulty gas cap. You may even encounter the issue that your lawn mower runs for 5 minutes then dies.
Electric lawn mowers don`t have spark plugs, meaning power is consistent and reliable. It also means you`ll never have to spend time or money checking, changing or re-gapping a spark plug.
The spark plugs are worn or damaged

If you find that your lawnmower keeps dying, or keeps stalling while cutting grass, then inspect the spark plugs. Look for signs of damage or wear. Something as simple as a cracked porcelain insulator can mean an electrode has been damaged or burned away.

Stale fuel, dirt, and debris are the most common cause of outdoor power equipment not starting or running properly. If you store equipment with untreated gas in the tank, it can lead to engine damage.
However, many users reported that using Craftsman Riding Lawn Mower for eight years or more is typical. Without proper maintenance, you can expect one-half of that lawnmower life expectation.
With regular upkeep and use, you can expect your Craftsman riding mower to last anywhere from 12-15 years. To help ensure a long life, it is recommended to keep the blades sharpened, check the oil, and maintain the belts and spark plugs.
A Dirty Carburetor Can Cause a Lawnmower To Start Then Die

By far, the most common issue that causes a stalled motor is a dirty carburetor. The carburetor on your engine is the thing that draws in air and mixes it with the fuel. Contrary to what the movies might make you think, gasoline itself is not very flammable.

My mower will start but won't stay running – Toro LX466 22HP Lawn Tractor 13RT61RH244
ANSWER : I am going to respond 2 times to this post. The first reply will be generic things to check.
First off check the oil level and make sure it is serviced to full.
If your having a lack of fuel (runing lean) you will need to check fuel flow at the carb fuel mainfold. It should fill a spray paint can lid in less than 10 seconds but teting flow rated of the main fuel line. If you have poor flow here… you need to check the fuel filter and the fuel tank outlet port for obstructions.

Good Fuel flow still shutting off…. remove the carb float bow and clean the debris from the bow’ and the treaded area where the fuel solenoid mounts Additionally you will have to again remove the main fuel line and spray carb cleaner in the float needle area to flush out any debris through the fuel hose connection.

For the second response I need to know which engine is installed on your mower by MODEL number if you can locate it. (there are 3 engines) At least try to find the engine model number. If you can not locate it Brand and HP of the engine (I assume 22 hp) Thanks for choosing FixYa,
Kelly

I have trouble starting a toro walk behind mower
ANSWER : All, I thought my carb was shot, so I replaced it. Still, start but no run (and had to use starting fluid). THEN!!! I noticed the spring to the “rev limiter” (just below and towards rear of carb) was not “tight”. The stupid bracket that holds the end of that spring had been bent down ~1/16″ and that caused all this heartache. CHECK YOUR REV LIMITER!!!

Where is the primer ball
ANSWER : It may not have a primer ball. If it does, it would be attached to the carberator. If it starts, but won’t stay running, that could mean your carberator needs to be cleaned/serviced.
