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 :

If your trimmer engine idles, but stalls on throttle, check the following parts: the gasket, primer bulb, fuel filter, air filter, fuel vent, fuel line, and carburetor. The repair and symptom guide will help you better identify the part needed to be replaced and how.
Remove the air filter and spray carburetor cleaner into the intake. Let it sit for several minutes to help loosen and dissolve varnish. Replace the filter and try starting the trimmer. If this doesn`t solve the problem, consider disassembling the carburetor to give it a more thorough cleaning.
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.
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.
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.
Use a 40:1 two-cycle oil mix ratio. One gallon of gasoline combined with 3.2 oz of two-cycle engine oil. Unsure of the age of your equipment? Use the 40:1 mixture.
If the engine is not revving up and cuts out before you reach higher revs then you need to do the following checks: Fuel: Make sure it is fresh and correctly mixed (see `Starting Issues`). Air filter: Make sure it is clean and unclogged. Fuel cap: Make sure it`s hand-tight.
Storing regular petrol inside a machine can cause blockages and gumming to the intricate fuel delivery parts, so the most important thing to remember is that whether you`re storing a chainsaw or garden power tool such as a petrol lawn mower you should store your tool without any fuel in it.
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.
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.
Put the gas in your car. oil/gas mix always has a green or blue appearance.
It`s simply 40 parts of fresh, unleaded fuel with 1 part of semi-synthetic 2 stroke oil.
When trying to start a flooded engine, the end goal is to re-establish the fuel-air balance in your vehicle. To do so, simply open the hood of the car and let the excess of fuel evaporate. After waiting for some minutes, try starting your car again, keeping your foot away from the gas pedal.
A flooded engine is an internal combustion engine that has been fed an excessively rich air-fuel mixture that cannot be ignited. This is caused by the mixture exceeding the upper explosive limit for the particular fuel. An engine in this condition will not start until the excessively rich mixture has been cleared.
If the engine is running fast (revving high):

Make sure that the choke is disengaged and the throttle hold has been reset by pressing the trigger. You can check the throttle cable to make sure there are no kinks found in it – however this requires a mechanical proficiency to strip down the machine uncovering the cable.

The choke is located before the throttle, and manages the total amount of air going into the engine. The choke is only used when starting a cold engine. When doing a cold start, the choke should be closed to limit the amount of air going in.
Most string trimmers use a flexible drive shaft inside the shaft housing even if the shaft is straight. These flex shafts can start to vibrate when they wear out, or when they aren`t properly lubricated. Vibration can also occur when the connection between the flex shaft and the trimmer head is loose or worn.
Yes. On a carburetor equipped motorbike with a gravity feed fuel system (no fuel pump), there is a vent in the fuel cap. This is so that air can enter as fuel leaves, otherwise you get no fuel flow. Fuel evaporates from the tank via this vent and also from carburetor bowls.
You can only leave petrol in a string trimmer for short periods. Anything longer than a month will cause damage to the engine.
If you`re unsure about how many coats of primer you need for the surface you`re painting, a paint store can advise you. Otherwise, start with one coat and check the surface after it dries. If it still looks rough, porous or heavily colored, apply another coat.
To provide an adequate fuel/air mixture, gas may be placed directly into the carburetor to prime the engine. Priming carburetors is a dangerous and unnecessary practice and can produce explosion or fire!
Trimmer line does tend to dry out over time and becomes more brittle. Storing it or soaking it in water will help reduce line breakage and make the line more flexible. Be sure to deplete your supply of last year`s line before you purchase new line and begin using it.
When: After every 25 hours of use. The spark plug will suffer from standard wear and tear as you continue to use your grass trimmer, which is why a regular inspection is important. If you spot any damage, simply replace it.
Always wipe or wash off any soil, clippings or other plant material from the blade or tool surface. Dry and then wipe all metal parts with an oily rag, minding the sharp edges, or spray them with lubricant.

Need to replace fuel lines on my Troy Bilt gas hedge trimmer. Where can I get replacement fuel lines… or better yet… what size are the lines and where can I buy a few feet of the lines. Note: I have reviewed the parts assembly and it would seem to indicate I have to replace the entire handle assembly (Part #1) instead of just buying replacement hose(s). Any help to resolve my issue would be greatly appreciated and thanks in advance
ANSWER : Replacement fuel lines should be readily available at your local lawnmower repair shop. Your TroyBilt hedger uses fuel line that is 3/32″ (2.4mm) interior dimension, 3/16″ (4.8mm) outside dimension, with a 3/64″ (1.2mm) wall dimension.
Most manufacturers don’t offer replacement line, only fuel tank assemblies. Find your local shop, and try to get the TYGON brand…it is yellow. Tygon lasts the longest. You should be able to buy it by the foot for less than $2 per foot. You will need 2 feet of hose to replace both lines.

Make sure to clean the in-tank filter when replacing hoses.

Good luck.

How do you get the fuel line connected to the fuel filter nipple on the bottom side of the gas tank on the Ryobi 725r gas trimmer?
ANSWER : You must run the fuel line through the back of the tank and out the filler hole,make your connections,i used a small amount of vaseline to make the connections.Then pull the filter into place,make sure some of the nipple of the filter pokes through,then slide the retainer ring on the hose and force it onto the filter nipple.

Have a craftsman 16″ chain saw 358.360260. Could not initially get it started after it had sat for a couple years with fuel stabilizer in it. When I went to use it the fuel had all evaporated and the fuel pick line was rotted. I replaced that with some difficulty but finally got it on. Saw still wouldn’t start. Replaced the fuel filter. Still wouldn’t start. Pulled the carb apart and cleaned and recleaned everything. Diaphragms were good and I didn’t adjust any of the mixture screws because as I said it ran fine before storage. Non of the carb passages were clogged. Fresh gas 40:1, good spark plug and good spark. Airfilter is good. Engine has maybe about 4 hours of total run time on it. It’s a ZAMA (?) carb. It will run for about 30 seconds when I manually prime it by pouring a small amount of fuel directly though the carb. When I was disassembling the carb the vent hose that goes back into the fuel tank seemed to have a small out of ?substance? in it which I cleaned out. It was right at the end the of the hose that goes back into the fuel tank and not up by the carb. It didn’t appear to be like your typical gummy deposits/varnish though. I hope it wasn?t some type of spongy check valve stuff that is supposed to be in there. That might explain some of my problems. Anyway, I also can not seem to get the primer bulb to fill. When I open the fuel tank, look in side and depress the primer bulb, air bubbles come out of the fuel filter. But when I let the bulb reexpand there’s no fuel that gets sucked up the hose. I can however seem to fill the primer bulb when the fuel tank is full and the chainsaw is laying on it?s pull cord side and the bulb is depressed a bunch of times. The saw will also start and run again for about 15 seconds then die. It’s definitely not getting/fuel and probably running out . Thanks.

Just bought a new 26ss gas powered weed eater. This is my 3rd time using it and it wont start. I keep it in my shed out of bad weather, so I know it’s kept in good condition. I havn’t used it in 2 weeks and last time I did it ran fine. Yesterday I followed the instructions to crank it and nothing. I have the proper gas to oil ratio, and like I said it’s brand new so I’m pretty sure it cant be the spark plug, and the fuel lines look in tact. One question I have gas in the bubbls just wandering what else it could be? Thanks!!!

My hedge trimmer will not start… Put in new gas
ANSWER : It’s not getting gas, due to being gummed up with old gas. Remove all of the old gas and mix up a batch of fresh gas&oil. Also get some carb cleaner. Put just a little of the gas&oil mix plus an equal part carb cleaner. Try to start it just to work the new mixture through the carb. You might use the spray start to help pull the new gas through. If it fires up on the new gas&oil&carbcleaner mix, shut it off and let it sit for an hour or two. Drain it out and try just a little gas&oiil without the carb cleaner. If all is well fill the tank. If not, repeat the whole process. If you can’t clear the gum this way you may have to remove the carb to clean it.
Good luck.
