Why Your Craftsman Lawn Mower Won’t Stay Running
A lawnmower that keeps shutting down during operation can be quite frustrating. As we discussed in our previous blog post, there are four different ways to fix your lawnmower. If it dies soon after it starts. This is because you may not be able to mow the entire lawn in one go.
If you have old or dirty fuel that plugs the fuel filter, clogs the fuel lines, or causes the carburetor to fail, your Craftsman lawn mower won’t run. There are also several other reasons for a Craftsman mower not running. These include a faulty spark plug, a dead battery, a faulty charging system, a plugged air filter, an incorrect throttle setting, or a faulty ignition coil.
You should always follow the safety instructions in your Craftsman mower’s manual.
Why Your Craftsman Lawn Mower Won’t Stay Running
If you run your mower on contaminated fuel or fuel that has been sitting around for a long time, it can have negative effects. A decrease in fuel stability occurs, and moisture is attracted to the fuel from the air. It can cause corrosion in the fuel system.
A clogged fuel system is caused by ethanol and moisture left behind in the fuel system. Gummy deposits will clog the fuel system preventing fuel from getting to the engine. For more information on which type of gas to use with your Craftsman lawn mower, read this article.
Why Does A Craftsman Lawn Mower Not Start?
Craftsman lawnmowers sometimes fail to start for a variety of reasons. Fuel problems or a filter cleaning could be to blame. When troubleshooting, it can be confusing to know where to start. Small steps can help us get to the root of the problem.
To discover what’s wrong, we can examine the issues that are easiest to resolve. In the next section, we will address the more complicated issues. It might mean getting a replacement part or working with unfamiliar components.
You should, however, be in a well-ventilated room before you start the process. Furthermore, here are a few tools you’ll need depending on the issue:
- Fluid for starting
- Gasoline that is fresh
- A deep socket and a ratchet
- A testing instrument for spark plugs
- Gage for compressibility
- The shop rag
- The container should be fuel-safe
- Disinfectant for pipes
- Adapter kit for carburetors
- Suitable for replacement of the carburetor
It’s time to get started troubleshooting!
What Causes Lawn Mowers to Fail?
When lawnmowers encounter clogged air filters, they stop suddenly. Continuing to use your lawnmower with a clogged, dirty air filter will severely damage the engine. A lawnmower’s engine will not get the cooling and ventilation it needs, and it will eventually fail.
Power loss occurs when your air filter gets clogged or dirty. It won’t work on wet or tall grass. Mowing your lawn twice before gasoline runs out allows you to mow it twice before it runs out.
Before you remove the carburetor from the lawn mower, perform these quick steps to isolate your fuel problem with the carburetor.
Craftsman fuel cap has a defect
Craftsman lawnmowers have a fuel cap designed with a vent to allow air to pass through. Without the vent, fuel cannot leave the fuel tank and reach the engine since a vacuum forms inside the tank.
With this problem, a cap may run briefly, but it won’t last long.
The mower will start when the fuel cap is removed after it has stopped running. It may be a problem with the fuel cap vent if it starts and runs fine.
After placing the gas cap back on your mower, allow it to run for a while to see if it shuts off, later on, indicating the cap is damaged.
Cleaning and unclogging the vent may work temporarily, but this doesn’t always work. If you need to replace your Craftsman fuel cap, I recommend purchasing one.
A Craftsman lawn mower’s carburetor can be easily accessed.
This component needs to be accessed first, so we need to know how to get there. Here are the steps you must follow to reach the carburetor:
- It is necessary to disconnect the spark plug wire from the spark plug.
- Take note of the location of the air filter housing. You can now remove the cover.
- The air filter should be removed.
- For the air filter base, remove the screws with a nut driver.
- Fuel must be drained if you haven’t already done so.
- Release the starter rope from its handle next.
- Your nut driver will come in handy to remove the screws from the blower housing.
- It is necessary to remove the blower housing.
- The carburetor can now be accessed completely. A bracket arm should secure it in place. Take it off the carburetor adapter.
- An upper component will be connected by rods. Remove them from the circuit. The lawnmower should be completely disconnected from the attachment at this point.
- In conclusion, remove the fuel line if you haven’t already.
In some cases, it’s not ideal to follow instructions through text. Below is a YouTube video showing how to do it:
In the case of a Craftsman engine overheating
