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 :
So, if your Mountfield mower won`t start, make sure you have plenty of fresh fuel, no engine filters are blocked and that your spark plug is clean and secure. You can also carry out maintenance tasks that should help keep your mower in good condition before storing your mower for winter, which you can read about here.
A full gas tank and oil reservoir are the essential first steps when checking why the lawn mower won`t stay running, but the problem could also be a dirty filter, clogged carburetor, improper fuel mixture, or a dirty spark plug.
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.
If the plug is clean or you`ve replaced it and the mower still won`t start, the issue could be a lack of fuel. Either the carburetor is dirty and not able to mist the fuel to be mixed with incoming air, or no gas is getting to it to begin with.
The pull cord mechanism on a lawn mower isn`t complicated, and the reason your cord isn`t catching is that one of the components of the flywheel starter assembly has failed under the stress of regular use. Typically it`s either worn or broken pawls, or a damaged pulley system.
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.
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.
If your lawn mower starts, runs for a while, then dies, check the ignition coil, gas cap, and spark plug. One or more of these parts could be causing your problem. Follow our repair and symptom guide to help you fix this.
Bad Spark Plugs
If the engine holds compression well, and the fuel system is working correctly, but it still won`t start, that tells us that your car`s spark plugs may not be working. The spark plugs ignite the air/fuel mixture inside the engine`s cylinders. It`s the resulting explosion that actually powers your car.
Broken, damaged or corroded wire. Timing. Improper spark plug gap. Faulty ignition coil.
Unbreakable and Reliable: diamondcord is the world`s strongest and most durable pull start cord, designed using patented technology that is five times stronger than steel.
Raises alerts in areas where personal triggers are unlikely to be worn. The emergency Pull Cord can be strategically placed around the home, in order to provide a user with a convenient means of summoning help in an emergency.
Ray: If your mower uses a 12-volt battery, use the jumper cables as you would when starting another car. Hook the positive cable to the positive terminal of the car battery. Then connect the other end of that cable to the positive terminal of the mower battery.
The problem may be in the recoil starter itself. A tangled coil of rope or a broken spring may be the problem. In many cases the recoil starter is easily replaced as a single assembly. DO NOT attempt do take the starter apart.
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.
A clogged fuel filter is most commonly caused by leaving old fuel in the lawn mower. Over time, some of the ingredients in the fuel may evaporate, leaving behind a thicker, stickier substance. This sticky fuel can clog up the fuel filter and make the engine hard to start.

My Z5426 won’t start. When I pull out the choke and turn the key, gas starts leaking out of the exhaust system just before it gets to the muffler. Last time it did start, it ran really rough. So, I turn off the engine and then tried to restart and that’s when I noticed the fuel leak.
ANSWER : Maybe bad fuel, fuel line leaking, flooding of the carburetor, since it did start and ran rough I am assuming that the gas was left set and more then likely this gummed up the carburetor, you will have to clean/rebuild it. If you have a can of carburetor clean you may be able to spray that into there and clean it up, I would not choke it to start it as it sounds like it got/is flooded/ing. Good Luck Tim

It tries to spin the engine but engine won’t continue to turn over unless I manually spin the top of the engine with my hand. Then it starts right up. I changed out the cables, solenoid with no help.
