What to Do When Your Lawn Mower Won’t Start: A Comprehensive Guide

Common Reasons why Lawn Mowers Won’t Start

To diagnose why your lawn mower won’t start, turn to the section on “Common Reasons why Lawn Mowers Won’t Start” with solutions in the form of sub-sections. Here, we will explore various issues that may cause problems with your mower, including fuel-related issues, airflow-related problems, spark plug and ignition system issues, and mechanical faults.

Fuel Related Issues

As a lawn mower owner, you might experience fuel-related issues. These can be empty fuel tanks, old fuel, clogged fuel filters, or contaminated fuel. To fix these, add fresh fuel, clean/replace fuel filters, and use gas from local stations with up to 10% ethanol.

Old gasoline can become stale and damage carburetors in the winter months. To avoid this, do regular maintenance and check fuel is clean and fresh. This will ensure your lawn mower lasts long and keeps your lawns looking pristine! If it’s having trouble starting, it might be an airflow issue.

Airflow Related Problems

Time to troubleshoot the lawn mower! It won’t start, so it must be an airflow related problem. Let’s assess the air filter and carburetor. A clogged air filter or dirty carburetor can reduce the airflow needed for combustion.

Check the air filter. Remove it from its housing and hold it up to the light. If you can’t see through it, that means blockage. Clean or replace the filter for a solution.

If that doesn’t work, inspect the carburetor. Use gum remover or carb cleaner spray to dissolve any gum blocking fuel flow in the carburetor’s passageways.

Lawn mower issues are so frustrating! We often don’t realize that lack of airflow is the cause. Knowing this will help you keep your lawnmower running smoothly season after season!

Spark Plug and Ignition System Issues

When it comes to lawn mower maintenance, spark plugs and ignition systems are often the cause of trouble. Dirty or worn out spark plugs can stop your mower from starting. Ignition timing, coil, and flywheel problems can be culprits too.

It’s important to check and replace spark plugs regularly. If you’re having trouble starting your mower, check these areas first. Remember to always gap spark plugs according to manufacturer specifications. Use a gauge tool to check and adjust the gap.

Pro Tip: Don’t forget to pay attention to other components too, like air filters and fuel filters. Proper maintenance will ensure optimal performance and longevity of your machine.

Mechanical Faults

When your lawn mower won’t start, it could be a mechanical fault. It could be a bad spark plug, broken starter cord, blocked fuel filter, or clogged carburetor. Ignoring these issues can get expensive or even require a new mower.

To find out, check the spark plug. If it’s worn or dirty, swap it with a new one. If that doesn’t work, take a look at the starter cord – fraying or breaking can cause a start-up issue. A clogged fuel filter can also stop the fuel from reaching the engine, which disrupts starting.

Moreover, a blocked carburetor can cause a non-start – if one of the jets is plugged, it messes with the air-fuel mixture. To find out if this is the problem, you’ll need to remove and clean it with the right cleaning liquid.

Once, my neighbor had trouble with his 1-year-old mower after cutting grass in the rain. We found rusty corrosion on the spark plug contact point caused by moisture and water-shortage. Before you call a repairman, make sure it’s not just ‘grass-phobia‘!”

Troubleshooting Lawn Mower Starting Issues
