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.
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.
A dirty carburetor is one of the most common causes for a lawn mower not being able to start after sitting unused for months or years at a time.
Possible cause 1: In some models, when you tip the mower, fuel can leak into the carbon in the cap, which restricts the venting of the fuel system. This can cause the engine not to start, or only run for a few minutes, then quit. POSSIBLE SOLUTION: Leave the cap to dry out or replace it with a new lawn mower cap.
Check the Spark Plug

Spark plugs that are old or don`t function well make it harder for the engine to start. This usually results in the person using the lawnmower needing extra muscle to get the machine running. Make sure that you invest in good spark plugs that will hold up well over time.

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.

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.

The most common cause of a mower that runs for thirty minutes and then dies is a faulty armature. A faulty gas cap is the second most likely cause.
If your lawnmower is starting and then stalling, the most likely issue is the carburetor. The most common issue is that the carburetor is dirty. Here`s what you need to know about how a dirty carburetor can cause a lawnmower to start, then stall out and die.
Disconnected, dirty or fouled spark plugs are common causes for engines that won`t start. For small engines, spark plugs typically need to be replaced every season or after 25 hours of use. You should also check to make sure the spark plug gap is set correctly.

Strimmer starts and runs but cuts out when at full power
ANSWER : Easiest place to look first would be to see if one of the fuel hoses has split. May be hard to see but that would cause it to **** air instead of fuel. Eventually, the split or hole would become so big that it wouldn’t stay running at all, and probably not even start. If that doesn’t do it, make sure the fuel you have is still good and try running a little Seafoam with the fuel and see if it clears up. After that, I would be looking at carefully cleaning the carburetor which may require dis-assembly as well as new gaskets etc.
