Common Causes For A Craftsman Lawn Mower Not Starting
Is your Craftsman lawn mower not starting? There could be a few common causes behind this frustrating issue. Let’s take a closer look at some of the potential reasons why your lawn mower won’t start:
Old Or Stale Fuel In The Tank
One common cause of a Craftsman lawn mower not starting is having old or stale fuel in the tank. Over time, gasoline can break down and lose its effectiveness. This can make it difficult for the engine to ignite and start. If you suspect that your fuel may be old or stale, it’s important to drain the tank and refill it with fresh gasoline.
Dead Battery Or Bad Fuse
If your Craftsman lawn mower has an electric start feature, a dead battery or a bad fuse could be the culprit behind the starting issue. A dead battery will need to be recharged or replaced, while a bad fuse should be replaced with a new one. Checking the battery and fuse should be your first step when troubleshooting a Craftsman lawn mower that won’t start.
Dirty Or Damaged Spark Plug
The spark plug plays a crucial role in igniting the fuel-air mixture in the engine. If the spark plug is dirty or damaged, it may not generate sufficient spark to start the lawn mower. Inspecting the spark plug for signs of wear or damage is essential. If you notice any cracks, burned electrodes, or heavy carbon buildup, it’s time to replace the spark plug.
Dirty Air Filter
A dirty air filter can restrict airflow to the engine, leading to starting issues. It’s important to clean or replace the air filter regularly to ensure proper air intake. A clean air filter allows the engine to receive the necessary oxygen for combustion, improving its starting performance.
Inspecting The Fuel Filter And Ignition Coil
In addition to the previously mentioned causes, it’s crucial to inspect the fuel filter and ignition coil. A clogged fuel filter can restrict fuel flow to the engine, while a faulty ignition coil can prevent spark production. Checking these components and replacing them if necessary can help resolve starting problems with your Craftsman lawn mower.

Below are some essential steps to help you troubleshoot a Craftsman lawn mower that won’t start.
Checking The Spark Plug And Fuel System

- Check the spark plug for signs of wear or damage, such as a cracked porcelain insulator or heavy carbon buildup at the electrode.
- Use a spark plug tester to determine if the spark plug is defective.
- Inspect the fuel system for any clogs or blockages, and ensure there’s fresh gasoline in the tank to avoid starting issues.
Cleaning The Carburetor And Air Filter
The carburetor and air filter play crucial roles in the engine’s performance. If these components are dirty or clogged, it can hinder the lawn mower’s ability to start. Taking the following steps can help address potential issues:
- Clean or replace the air filter to ensure proper airflow to the engine.
- Inspect the carburetor for any dirt or debris and clean it thoroughly to remove any obstructions.
Inspecting And Adjusting The Engine Speed
The engine speed directly impacts the performance of the lawn mower. If the engine speed is not properly adjusted, it can lead to starting issues. Here’s what you can do:
- Inspect the engine speed and adjust it according to the manufacturer’s specifications.
- Ensure that the engine speed control components are functioning correctly.
By following these steps to troubleshoot a Craftsman lawn mower that won’t start, you can potentially identify and resolve the issues preventing your lawn mower from starting. However, if the problem persists, it may be necessary to consult a professional to diagnose and fix the underlying cause.
