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 :

Checking the Fuel Mix

The most common problem with a strimmer not starting is that there`s a problem with the fuel mix. Double check that you`ve used 40 parts fresh unleaded petrol to 1 part 2-stroke oil (40:1). Check the petrol you`ve used isn`t stale.

A gas trimmer`s engine may be faulty. The air filter or exhaust port may be blocked. The trimmer may need lubrication and cooling fins or air passages may be blocked. A cordless trimmer`s battery or charger may be faulty.
Something could be blocking the cap, keeping the line from advancing. To inspect and replace, simply remove and clean out the bump cap housing of any debris that may be impacting its operation. If the cap is damaged, replace it. The cap allows you to feed more line when you tap it on the ground.
Fuel pump failures can be caused by electrical faults, old age (wear) or fuel contaminants (dirt, moisture or bad gas). Fuel pump failures often occur without warning. Fuel pumps, injectors and pressure regulators are the three most commonly replaced fuel system components.
Electrical issues: Electrical faults are also significant contributors to fuel pump failures. The most common electrical issues are rusted connectors, loose connectors, or melted wiring and connectors.
If your trimmer won`t turn on, especially if it has not been used recently, you may simply have a drained battery. Plug your trimmer into your charger and see if anything happens. Ideally your trimmer will recognize it has been connected to a power source and charge its battery.
A clogged carburetor is most commonly caused by leaving fuel in the string trimmer 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.
If your 2-stroke brushcutter fails to start, the simplest explanation is that there is not enough fuel: in this case you simply need to top it up. A 2-stroke brushcutter engine runs on fuel/oil mixture, which you can buy ready prepared, such as EFCO-Mix Alkilate alkylated mixture in a 5 L can.
When your trimmer starts and runs on choke, it could be because the check valve in the gas cap is clogged. Start the trimmer and gently unscrew the gas cap halfway off. Turn the choke off and assess. If the engine is still running, that means the gas cap may be the culprit.
Your Mower Won`t Start:

Other possible causes include: 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.

The most common reason a pump fails is wear on the pump from improper lubrication or over-use. The best way to explain a failed fuel pump due to wear and tear is to explain what other reasons may have lead to a failed pump: Most fuel pumps are lubricated by the fuel in the tank itself.
The PCM will ground the fuel pump relay which supplies power to the fuel pump under some specific circumstances. As a car sits, the fuel pressure gradually decreases and modern cars don`t run without fuel pressure.
Fuel pump failures tend to be sudden and unpredictable, with few symptoms to warn the motorist that trouble is brewing. And the higher the mileage on the vehicle, the greater the risk of a fuel pump failure.
Your petrol-powered engine requires a mixture of petrol and engine oil. The quality of the petrol and oil is extremely important to the running and life of the engine. Unsuitable fuels or mix ratios that do not comply with the specification can seriously damage the engine (piston seizing, excessive wear.)
How Does A Grass Trimmer Work? A grass trimmer is a garden tool that uses a nylon line instead of a blade to cut the grass. The propulsion system spins the wire at such a speed it is able to cut through the grass with ease.
This can be due to corrosion, scratches or general wear. As a result, the cutting edges of the cutter comb of your blades are no longer sharp, reducing their ability to cut. Sharpening the blade is required to reface the cutting surfaces restore these sharp edges.
It is possible that the battery of your Philips Groomer has run out. We advise you to fully charge your groomer and then try turning it on again. Note: Charging and running time can vary based on the model of your groomer. Please check your user manual for more information.
Just Like Spark plug fouling, too much oil in the gasoline, inferior oil, a dirty air filter and/or continued operation at less than full throttle will plug the screen with carbon deposits. This prevents exhaust gases from flowing out, which leads to power loss or not running at all.
If you really must strim wet grass, you can. But make sure it`s only once in a while. Cutting grass when it`s wet also increases the chances of lawn diseases taking a hold and damaging your lawn.
I recommend using a string trimmer (weed wacker) or Dutch Hoe to trim weeds or perennials in unwanted areas instead of weeding by hand. If taller perennial plants are invading your paths or larger areas outside your garden, cut the stalks before they get too tall with a string trimmer or Dutch hoe.
The manufacturers were not able to control the pollution levels that were emitted from the two-stroke engine and because of which they couldn`t comply with the new emission standards that were set by most of the countries. Because of this, the two-stroke engine had to be killed.
If the engine is bogging before it gets to the powerband, then the air-fuel mixture is most likely off. When the engine isn`t burning the proper amount of fuel and air, it won`t produce power and accelerate, giving you the annoying and dangerous “bog”.
A clogged carburetor is most commonly caused by leaving fuel in the hedge trimmer 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 or run roughly.

Hard to start, wont idle. – Craftsman 25cc Gas Line Trimmer
ANSWER : Hi o9sbornes1325…

Sounds like you have dirt/debris in your carburetor jets,fuel passages or a diaphgram that is becoming non-flexible.Be sure to check your fuel tank for water and dirt/debris, if there is water/debris then you need to clean your tank.Also check you fuel line condition after a while they will degrade and need replacment.Make sure you are getting spark at the spark plug, to do this:Remove your spark plug and check to be sure you are getting fire at the spark plug.You do this by grounding the plug on the head of the engine and pulling the crank rope, if you are getting spark then:Check/Clean/Replace your fuel filter if you have one, normally they are located in the fuel tank of weedeaters.When you remove your fuel lines from the carburetor be sure to make a drawing to how the lines are connected to the carburetor.Normally the big line will be the line the fuel filter is connected to inside of the tank.The smaller of the two lines is the return to the fuel tank from the carburetor after it is pumped thru the carburetor by the primer bulb.Also make sure you are using fresh fuel…and oil mix if your using a two cycle mower or weedeater with the oil to the right mixture and not too much oil as it can cause hard starting.If the mower/weedeater is over a couple of years old, then I recommend that you buy and install a new carburetor repair kit,because the diaphragm will get hard and that will cause it to be hard to crank.Sounds like you will need to clean the carburetor or replace your carburetor internal rubber parts like the diaphgram and O rings.I recommend that you use a laquer thinner type cleaner to clean and dissolve the laquer build-up in the float and needle jet passages.Be sure to remove all plastic and rubber parts before using the laquer thinner because it can dissolve the plastic parts and render them unuseable.Be sure to use compressed air to blow out all the fuel and air passages.Be careful when blowing out the passages, because there are sometimes small rubber type seats in the bottom of some of the passages.Sometimes you can get by with priming the carburetor or using starting fluid and letting it run a few times like that and it will flush the gunk out of the jets,but most of the time you will need to rebuild the carburetor.Keep in mind that the float (if you have one) for the carburetor must be level when you go to reassemble the carburetor or follow the instructions you get with the carburetor kit.When you clean your carburetor and remove the jet screws, you will first need to lightly seat the jet screws.But before you lightly seat the jet screws count the number of turns it takes to seat the jet screws from their original position.Be sure to mark the turns down on a piece of paper.That way when you put the jets back in, you know to lightly seat them first and then turn them back out to their orginal position before you started.Once you have your carburetor rebuilt that should solve your problem.

Craftsman line trimmer 25cc 17″
ANSWER : Hi sukfish…
What caused the old bulb to crack is time and fuel…
Make sure you are getting spark at the spark plug, to do this:Remove your spark plug and check to be sure you are getting a bright blue spark at the spark plug.You do this by grounding the plug on the head of the engine and pulling the crank rope, if you are getting a nice blue spark then:
Sounds like you have dirt/debris in your caburetor jets,fuel passages or a diaphgram that is becoming non-flexible. Check/Clean/Replace your Air Filter, a dirty air filter can make your engine run to rich with fuel.
Note: ALWAYS USE COMPRESSED AIR TO CLEAN YOUR JETS AND PASSAGES, VERY IMPORTANT.
Note:Before you disassemble the carburetor:Mark each piece with a awl, or some kind of instrument that will make an alignment scratch before you disassemble the carburetor into separate pieces.That way you will know which way it goes back together when you reassemble it.
Sometimes you can get by with priming the carburetor or by using starting fluid and letting it run a few times like that, and it will flush the gunk out of the jets,but most of the time you will need to rebuild the carburetor.Be sure to check your fuel tank for water and dirt/debris, if there is water/debris then you need to clean your tank.Check you fuel line condition after a while they will degrade and need replacment.
Check/Clean/Replace your fuel filter if you have one, normally they are located in the fuel tank of weedeaters.When you remove your fuel lines from the carburetor be sure to make a drawing to how the lines are connected to the carburetor.Normally the big line will be the line the fuel filter is connected to inside of the tank.The smaller of the two lines is the return to the fuel tank from the carburetor after it is pumped thru the carburetor by the primer bulb.Make sure you are using fresh fuel…and oil mix if your using a two cycle mower or weedeater with the oil to the right mixture and not too much oil as it can cause hard starting.If the trimmer is over a couple of years old, then I recommend that you buy and install a new carburetor repair kit,because the diaphragm will get hard and that will cause it to be hard to crank.The diaphgram may look good and flexible, but it can be deceiving and not act as a fuel pump as it should because it has become too hard and will cause hard starting,start and run and shut off, etc.
When you clean your carburetor, I recommend that you use a laquer thinner type cleaner to clean and dissolve the laquer build-up in the float and needle jet passages.Be sure to remove all plastic and rubber parts before using the laquer thinner because it can dissolve the plastic parts and render them unuseable.Be sure to use COMPRESSED AIR to blow out all the fuel and air passages.The higher air pressure is needed to blow some of the trash/debris from the fuel or air passages.Be careful when blowing out the passages, because there are sometimes small rubber type seats in the bottom of some of the passages.Keep in mind that the float (if you have one) for the carburetor must be level when you go to reassemble the carburetor or follow the instructions you get with the carburetor kit, or you could also ask the parts man that you get your kit from.When you clean your carburetor and remove the jet screws, you will first need to lightly seat the jet screws.But before you lightly seat the jet screws count the number of turns it takes to seat the jet screws from their original position.Be sure to mark the turns down on a piece of paper.That way when you put the jets back in, you know to lightly seat them first and then turn them back out to their original position before you started.Note:The little spring inside of the carburetor goes under the float arm.That is where your fuel inlet needle/float valve is located…on the arm at the end.Normally there is a small indetion in the carburetor base and a small protrusion on the underneath of the float arm where the spring will be in the right postion for installation.The spring will set in the indention and you will install the float arm with the needle/float valve and float rod into position over top of the spring,you will push down until it is in position and then you can tighten the screw that holds the float arm assembly in position.Once you have your carburetor cleaned/rebuilt that should solve your problem.Please take time to rate me
