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 :

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 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.

If your lawn mower starts, runs briefly, then dies these are the four most common reasons that`s happening: Dirty carburetor / clogged carburetor bowl. Old gasoline that has gone bad. Dirty or defective spark plugs.
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.
Problems arise in cold weather, because cold air is oxygen-rich, as you can imagine throws the ratio way off. Without the choke, the engine gets too much air for the amount of gas the engine receives. We call this a lean condition. A mower just won`t start or starts and stalls right away when the AFR is too lean.
If your lawn mower starts, runs for a while, then dies, check the ignition coil, gas cap, and spark plug. One or more of these parts could be causing your problem. Follow our repair and symptom guide to help you fix this.
Mower Gas Cap

If the tank is sealed, the fuel becomes air locked, and the mower stalls. This typically happens after a short period between ten and thirty minutes and also depends on factors like weather and gas tank fuel level.

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.
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.
Your lawn mower turning over but not starting due to several reasons, such as a faulty or disconnected plug, a disconnected spark plug wire, a clogged air filter, or a contaminated fuel tank. A faulty carburetor, a dirty cutting deck, or a dysfunctional flywheel brake can also cause this.
If the engine starts, but does not run smoothly, it means that the spark plug and ignition system are in order and you need to look elsewhere for the source of the problem. The usual culprit is air intake or fuel system related.

ANSWER : Sounds like the engine needs oil. You can also spray WD40 around the shaft. This will help loosen it up a bit, perhaps enough to allow it to start. The other possibility is that you have something wrapped around the shaft that is causing a restriction to the pulley.
Hope this helps.

The chain saw starts but stops after 30 seconds
ANSWER : Sounds like the engine is trying to run on just the fuel pulled into the carburetor when primed, but is not pumping new fuel in. Remove the carburetor and inspect the gaskets and heat insulator block behind the carburetor for cracks or other damage. Make sure the small air passage is clear from the cylinder to the carburetor base. Remove the carburetor upper chamber cover and carefully inspect the pump diaphragm and two valves. Any defects here will prevent intake of fresh fuel. Check the fuel lines for decay or other damage. Check the fuel filter for plugging. Make sure the air filter is clean. Hope this helps!
