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 motor starts initially but then won`t stay running, that means it`s getting a good initial injection of gas from the primer bulb, but then the carburetor starves off the oxygen it needs to keep combusting. When your carburetor is clogged, the cause is likely to be evaporated gas that has gummed up the pores.
A faulty or dirty spark plug could be the reason your lawn mower won`t stay running. It might produce the initial spark, but the spark won`t be enough to keep the engine running if the plug is clogged with dirt and oil. Spark plugs are usually located on the front of a push lawn mower and connected to a black cable.
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.
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.
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.
If petrol is coming out of your primer bulb, this means that it is backing up in your carburettor and flowing out of the primer tube. The float-valve in your carburettor has most likely got stuck and just needs to be adjusted.
Over-priming can happen when the primer bulb is pushed too many times. This can result in the engines of your lawnmower becoming flooded by fuel. The fuel can spread into the combustion chamber, where it can gather and pool. Under this condition, the spark plug can get too wet and will not ignite.
Stale fuel can cause all sorts of problems, including preventing your lawn mower from starting and affecting its performance, and is one of the major contributors to mower breakdowns.
Check the Fuel Filter
To start, tap the side of the carburetor to help the flow of gas. If that doesn`t work, you might have a clogged filter. Not all lawn mowers have a fuel filter, but for the ones that do, it`s usually located in the fuel line or the fuel tank.
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.
Not all mowers are fitted with a primer bulb. But all mowers will employ some type of system that adds extra gas on cold starts. If you can`t locate the primer, it is likely your mower doesn`t have one.
Put the carburetor float and other components in a large container with your Simple Green Pro HD solution, and soak thoroughly. Use a brass brush to scrub all metal components, and a stiff nylon brush to scrub plastic pieces. Make sure the tiny vents get cleaned.
A primer bulb is important because it helps to fill the carburetor with the correct amount of fuel. You may need to fix or replace your primer bulb if: It is not creating proper suction/pressure. It has a crack in it. It is not creating pressure when you press it.
“Water in the engine is a killer.” Smart move: At the end of the season, take 10 minutes to drain the tank or run the engine dry. Never change or add oil. Moving metal parts need oil, and an engine that`s denied clean oil, and enough of it, will overheat for sure.
As a rough rule of thumb, a single-cylinder mower with 500-750 hours would be considered a high miler, but that`s not to say it`s all worn out. A well-maintained mower will go on and on, as said earlier, my own ride-on mower has about 1000 hours and still pulls its weight around here.
Ordinary copper and nickel spark plugs should be changed every 30,000 to 50,000 miles, unless otherwise suggested by the spark plug manufacturer. Platinum and iridium spark plugs tend to last longer than standard copper and nickel spark plugs. Expect to change them every 60,000 to 150,000 miles unless otherwise noted.
A dirty or fouled spark plug can cause your lawn mower to not start. It can also work itself loose, causing issues. If the spark plug appears to be seated correctly but the engine doesn`t start, a new one may be in order. For a few dollars, this easy fix can get your small engine working again.
Knowing you can expect your residential lawn mower to last you around 450-500 hours is helpful in the decision-making process. The closer you are to the end of the expected lifespan, the more you should consider replacing it if a large issue occurs.
Expired gasoline can damage internal components of your carburetors, deteriorate fuel lines and seals, and cause a varnish build up that could clog small fuel ports which are necessary for your machine to start and run. Fresh gasoline is essential to the proper starting and running of a machine.
Petrol starts to go `stale` after about 30 days from purchase. It will go stale whether it is stored in a jerry can or inside your lawnmower`s engine. It is important not to use petrol that has gone stale in your lawnmower.
Gasoline has a shelf life of just 3 to 6 months. Over time, bad gas can gum up your mower`s engine. Siphon out the old fuel from the tank to get rid of bad gas.
One of the more common questions we get concerns either the overwhelming smell of gas coming from the carburetor or fuel leaking out of the bowl or overflow. Both conditions are typically caused by a stuck or worn float needle valve.
It means that the needle valve in the fuel bowel is stuck in the open position. Usually the gasoline fills the carburetor bowl up to a certain level and then the carburetor float will lift the needle and close the valve so no more fuel will come in.
If the filter gets clogged, you will likely encounter issues with your lawnmower. This can be something as simple as an annoying sputter when you try to start the mower, difficulty getting it started, or it can cause the mower to idle unevenly.

ANSWER : Without more info it’s hard to say. This could be something as simple as a dirty lid “o” ring, if it is streched out or cracked you will need a new one. If not you can clean with dish soap then when you relube “o” ring use teflon or silicone grease then wipe excess off as this excess will collect dirt, also clean lip of pump pot also. If this is not the problem then you may need to replumb pump or replace seal.

The well pump is running, but no water is supplied to thr irrigation lines. once I put water in the pump housing by removing the pump guage the pump pumps water through the irrigation lines. when it shuts down, iloose the prime again. what should I do?
ANSWER : Sounds like you have an air leak. First check your fittings, next carefully run water over the pump seals (avoid getting water on the motor or you’ll hurt yourself and the pump if not worse) the pump will prime if the leaking seal is covered with water. Take your time and be careful and it should only be a matter of a loose fitting or simple seal swap.

Running pump stopped
ANSWER : I assume that the plug in is working properly. Always check power supply first. Is there a GFCI circuit that it is plugged into. Then check the pump to make certain it us turning. How long had it been on before unplugging it. It could be worn out. Sometimes it takes a jolt to start the motor again. How big is the motor. Possible bad capacitor. Could be a solid state motor, then it’s bad. Is it a magnetic motor, that could be turning the wrong way.

It will start out with a good flow then will not pump any water even though it is keeping its prime.
ANSWER : You have some debris floating around somewhere. If you are pumping from a pond or a rain-barrel, you might have debris clogging the inlet. Or maybe you have a stone in the impeller – if your outlet is on top of the impeller a stone will sink to the bottom so you could have flow initially, but the stone would be carried up to clog the outlet within a few seconds. Or you might have stone in the hose feeding into the impeller – that stone could roll back down the hose even though you don’t loose prime.
