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 the throttle arm doesn`t snap back, or it snaps back “weakly”, then a throttle return spring will need to be added. If you`re unsure about whether you need to add a throttle return spring or not, we suggest adding one to your order just in case.
There are two types of throttle return springs: one is attached directly to the carburetor or throttle body, while the other is part of the throttle cable. If the throttle return spring is broken, missing, or damaged, the throttle cable will not easily return the valve back to its resting position.
Note: Not all diameters are approved for all STIHL trimmers – please refer to your instruction manual to see what diameters of trimmer line are approved for your model of STIHL trimmer.
It uses dual 0.08 or. 0950-inch cutting lines on a 15-inch diameter head.
Most styles and weights are interchangeable, so you can use non-OEM (original equipment manufacturers) line. However, larger/heavier line may not fit every string trimmer. Replace old trimmer line every spring. It could turn brittle over the cold winter and break more easily.
The universal attachment works with most brands of attachment-capable trimmers. This edger attachment makes it easy to clean up the lines on your sidewalks and driveways to a professional standard. The large rubber flap protects the operator from debris, and the large guide wheel makes edging easy.
A trigger spring is placed behind the trigger of a firearm so that when the trigger is pulled, it`ll return to it`s original position once the user releases the trigger.
As indicated above, the job of the throttle return springs is to “return” the throttle to a closed position. When the spring is damaged, the throttle body will remain open until either the pedal is manually drawn back by a driver`s foot or gravity takes over and helps to close the throttle.
The way it works is quite simple – the driver presses down on the accelerator causing the cable to pull the butterfly valve, and this in turn allows for air to enter the engine. As you start to ease up on the accelerator pedal that valve begins to close and allow less air into the engine.

How do I replace the trigger on the Huskie 350? Does it just snap out, is there a pin to drive out or do I have to separate the case. If I have to separate the case, how?
ANSWER : To remove the the trigger there is a alloy pin that needs be be driven out. Before you can take the trigger out, you need to remove the trigger lock ( dead man ) to remove the trigger lock, gently pry the two halfs of the tank apart at the rear opening where the lock sits, this will allow the back end of the throttle lock to pop up, once up pull the throttle lock toward the rear of the saw and it will come away ( bayonet fitting in the tank ) the trigger will now come out with its spring once the pin is removed.

How does the spring on the throttle trigger supposed to be placed to maintain tension for a working lever on an Echo 2100 grass trimmer? What is the trick to placing the spring correctly on the trigger mechanism? I have placed the spring on the plastic trigger mechanism, but there doesn’t seem to be any tension for the trigger to spring back. I placed the cable first in the slot of the trigger and then place the spring into position, but the trigger doesn’t spring back into the starting position. What am I doing wrong? There seems to be only one way to place the spring on the trigger mechanism. Can you please provide me with some sound advice or e-mail me a picture of how it is suppose to be assembled in case I’m doing something wrong? Thanks, Don

Have a Husqvarna 41 about 10 years old. Takes a lot of pulling to get it going but once running it woks allright. Lately it will not start and after new gas and plug it starts but when I engage the trigger to start cutting it totally cuts out and I have to pull it many times to get it going again And when I pull on trigger it dies after 20 seconds. Any ideas on what the problem is?
ANSWER : Hi
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 chainsaws.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 chainsaw 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

How do i rewind the recoil spring on my craftsman lawn mower?
ANSWER : Normally these small engines use a clock spring to retract the rope.
Remove the cover on the top and you should find the spring either broken or the tab where the spring end has broken off or jumped out of the mount.
You will need to pre-load the spring with enough tension to retract the rope.
Remove the pull handle from the rope, load the spring and then wrap the rope around the pully holding the pully and spring in the loaded position. place the end of the rope through the hole and tie up the handle. The rope should pull and retract without being installed on the engine.
