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.
Inspect the V-belt for damage and replace it with a new one if necessary. Damaged control cable – A broken, or misadjusted, control cable will prevent the mower from self-propelling as well. If the cable is intact but doesn`t move freely, you can try applying a small amount of lubrication to the cable.
An airlock is one of the common causes why your mower won`t start after running out of fuel. An Airlock occurs when air replaces fuel in the fuel lines. As you refill your fuel tank, you could push the air towards your mower`s carburetor, which keeps the new fuel from reaching the engine.
Check for blockages. One of the reasons for your lawn mower being hard to push could be that there is debris, grass or branches stuck under the product.
The reasons why mower is not moving forward or reverse is that the battery is dead, or due to clogged fuel line. Additionally, malfunctioning transmission, or a broken drive belt, also a faulty spark plug, even when friction wheel isn`t in contact with the friction plate, or damaged Tires.
So can you push a self-propelled lawnmower? You can push a self-propelled lawnmower, it won`t damage the transmission in any way. However, it may be difficult to do so, self propelled mowers are a little heavier than a regular push mower.
Self Propelled Mower. Self-propelled lawnmowers have a transmission that propels the machine forward, so the user does not need to push it, and instead guides it.
A failing fuel pump is a common factor in hard starting vehicles. Over time, a pump can wear out and not deliver the correct amount of fuel that an engine needs to run as it should. Clogged or dirty fuel filters, injectors, and lines can also restrict fuel delivery.
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.

After a rainny week, bad fuel developed in my fuel tank before I tryied to cut the grass. Now my mower runs high and low speeds and cuts out when cutting 6-8 inch grass.

Can you please help me locate the carburetor, resolove my issue, or both.
ANSWER : Yes, you are right, the carburetor does need cleaned. I’m send you a link to a video that will help you do this job: Good Luck!Jim

Seems to start easily run for a few minutes and then slow and stop–bulb remains full –gas is good–have tried half choke in case too lean–did not solve–also seems possibly related to the angle I hold it at–seems to cut out quicker if blower tube angled more downward.
ANSWER : Your filter may be hanging up in the tank. you also my be losing compression

My Husqvarna 128cd weedeater would run with choke on but not in the run position. Sometimes it would run in the run position but would not stay running. I had it running and then it cut off. I now cannot get it to crank at all. Any ideas
ANSWER : More than likely a fueling issue, wrong fuel air mix or air leak somewhere

It’s brand new, when I finally get it started it will run good for about 1 min. or less, and then it dies. I pull the choke out all the way, pull it a couple of times, push it half way in, it starts but it’s like it doesn’t have the power to turn the chain, bogging out and then it dies, I will never buy another homelite product, or recommend anyone else to, this is my second one, the first one leaked gas, Home Depot really should quit selling them, there making you look bad too!!

Mower runs at slow speed only
ANSWER : Sounds like you will need to clean your carburetor.
Sometimes you can get by with priming it a few times, 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.If the mower is over a couple years old, then I also recommend that youbuy and install a new carburetor repair kit, because the diaphragm willget hard and that will cause it to be hard to crank.When you clean your carburetor and remove the jet screws, count the number of turns it takes to seat the jets from their original position.That way when you go to put the jets back in, you know how many turnsthey were in/out.Please rate me, ThanksGood Luck, I hope this helped
