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 :

Other things that could cause this issue are bad fuel, weak/colapsed/kinked fuel line, faulty spark plug, faulty ignition/coil, oil over full, clogged air filter, plugged/dirty carburetor, worn engine parts internal rings/valves/etc.
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 full gas tank and oil reservoir are the essential first steps when checking why the lawn mower won`t stay running, but the problem could also be a dirty filter, clogged carburetor, improper fuel mixture, or a dirty spark plug.
Condensation inside the gas tank is one culprit, but moisture can also enter the system through a loose or ill fitting gas cap. The best solution is to drain the mower`s gas tank and refill it with fresh gasoline. A clogged fuel filter can also cause a mower engine to die.
Examine the plug cap for arcing and the coil wire for chafing. If damaged, it will cause an intermittent no start. Higher temperatures create higher resistance to the flow of voltage; that`s why coils usually fail when the mowers are hot and start working again when the engine cools.
Loose bolts are a common culprit in a mower engine that shuts down when hot. Check and tighten the bolts that hold the carburetor in place, the bolts that tie the air intake manifold to the block and the bolts that hold the head to the engine block.
What`s happening? This is a normal function of the seat safety switch. With the blades engaged, weight from the operator allows the seat safety switch to keep the engine running.
One of the common problems with Husqvarna riding mowers is their sudden power loss. If you ask our lawn care team, the problem stems from different reasons like bad gas in the fuel tank, plugged air filter, broken cooling pins, dirty carburetors, and clogged fuel lines.
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.
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.
You Lose Power in the Middle of Mowing:

Here`s why this happens and what you can do: Dirty Air Filter on Your Lawn Mower: Clean or replace. Dirty Spark Plug: Clean or replace. Build Up of Clippings & Debris: Clean underside of your lawn mower deck as noted above.

The carburetor might be clogged. A clogged carburetor is most commonly caused by leaving fuel in the engine 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.
Under certain circumstances, there are a few issues that can cause lawn mower engine overheating. A lawn mower engine overheating can lead components to expand, seize up, and combust. Read more to see what can cause your lawn mower engine to overheat, and how to resolve the issue.
An easy solution is to remove the mower casing and clean it of dirt and debris. Low Oil Levels can also cause overheating. With not enough oil circulating, internal friction occurs preventing heat from not being reduced. Be sure to check your oil level each time before you start your machine, and add oil if needed.
You can use air cooling to cool down your lawn mower. Turn it off first, and then cool your mower down by just letting it sit. See to it that no flammable materials can be found nearby. When it is cold, you can check for the cause of its overheating.
Clogged or Dirty Air Filters

Dirty air filters are one of the most common reasons lawn mowers sputter. Dirt can be present in the apertures that lead from the carburetor and the fuel filter and interrupt the flow of fuel supply to the combustion chamber. You want to be sure to clean or replace dirty air filters.

Use carburetor cleaner to remove deposits, clogs & debris

Luckily, you can take care of many of these problems quickly and easily; often without even removing the carburetor from the engine.

Husqvarna Long Life Safety Blades should be replaced every 6-8 weeks and Husqvarna Endurance Safety Blades every 3-4 months. Replacing your Automower® blades is relatively straightforward. If you`re not sure how to do it, it`s always best to have your Elite Automower® Dealer do it for you.
The Husqvarna Group (Swedish pronunciation: [ˈhʉ̂ːsˌkvɑːɳa ˈɡruːp]) is a Swedish manufacturer of outdoor power products including robotic lawn mowers, chainsaws, trimmers, brushcutters, cultivators, and garden tractors.
With the right maintenance, your mower can live well and strong for about 15 years. With the peak season of mowing approaching: here are Husqvarna`s best tips on how to care for your machine.
An engine that will fire and run with the choke closed but dies when the choke is opened likely has debris at least partially blocking the fuel passages in the carburetor. In this condition the closed choke provides enough extra fuel to enter the engine to overcome the lack of fuel flowing through the other passages.
A dirty air filter inhibits the flow of air into the carburetor. Clean or replace the air filter to stop the mower from sputtering to a halt. Too much air can also cause problems for the engine. A bad cap on the gas tank is the first place to look.
Over time, a spark plug will wear out. Eventually, the spark will no longer be powerful enough to fully ignite the air and fuel. You are likely to notice power loss including bogging down when cutting grass because of a worn spark plug. Removing and replacing a spark plug is easy.

Husqvarna 240 want start at all – Husqvarna Chain Saw 18" 450 Model 966955438
ANSWER : Sounds like the ignition module or spark plug. The ignition module is what controls the spark plug that gives your saw the firing capabilities. Before you purchase one of those, replace the spark plug and see if that works. The 240 is a newer husqvarna; so I am skeptical to say it is the ignition module. However, any new product can have a bad part on it. Your saw may have gotten flooded and won’t start. Make sure your gas mixture is 50/50 gas to mixing oil. Always use fresh gas. If you make up gas and don’t use a whole gallon at a time, put some fuel stabilizer in the mixture; so it will still be fresh the next time you use it.

Husqvarna chainsaw stops when using it
ANSWER : Check for spark by removing the spark plug and grounding it to the
metal part of the cylinder. It should spark a bluish, yellow strong spark when you pull the starter rope. Make sure the SPARK PLUG is good . Get a known good spark plug. By using a plug that you know is GOOD, it will eliminate any chance that you have a bad plug and that the ignition module is good too. If the known good plug is not sparking then you may have a bad ignition coil. For replacement of that one you will have to remove the entire left coil cover and the ignition coil is by the flywheel or under it.
