How to Start a Lawn Mower with Old Gas

Starting a lawn mower with old gas can be a frustrating ordeal, but with the right knowledge and a little bit of effort, you can get your mower up and running smoothly. In this comprehensive guide, we will walk you through the steps to revive your lawn mower engine using old gas. We will cover a range of topics including understanding the effects of old gas on your lawn mower, how to properly prepare your mower, and various troubleshooting techniques to get your engine running in no time.

Understanding the Effects of Old Gas on Your Lawn Mower

Old gas, also known as stale gas, can cause several problems for your lawn mower engine. Over time, the volatile components in gasoline evaporate, leaving behind a gummy residue that can clog fuel lines, carburetors, and injectors. This residue can prevent your engine from starting or running smoothly. Additionally, the octane rating of old gas decreases, which can lead to poor combustion and decreased performance. It is important to address these issues before attempting to start your lawn mower with old gas.

Preparing Your Lawn Mower

Before attempting to start your lawn mower with old gas, there are several steps you need to take to ensure the best possible outcome.

1. Drain the Old Gas

The first step is to remove the old gas from your mower’s fuel tank. Here’s how:

  1. Locate the fuel tank on your lawn mower.
  2. Place a fuel container below the fuel tank to catch the old gas.
  3. Remove the fuel cap and tilt the mower towards the container to drain the gas.
  4. Once all the old gas has been drained, dispose of it properly according to local regulations.

2. Replace the Fuel Filter

After draining the old gas, it is important to replace the fuel filter to prevent any debris from contaminating the new fuel. Follow these steps:

  1. Locate the fuel filter on your lawn mower. It is typically located between the fuel tank and the carburetor.
  2. Disconnect the fuel lines from the fuel filter.
  3. Remove the old fuel filter and install a new one in its place.
  4. Reconnect the fuel lines to the new fuel filter.

3. Clean the Carburetor

The carburetor is often affected by old gas residue, which can prevent it from functioning properly. Follow these steps to clean the carburetor:

  1. Remove the air filter cover and air filter from the carburetor.
  2. Spray carburetor cleaner directly into the carburetor throat, following the product instructions.
  3. Use a small brush to clean any remaining residue or debris from the carburetor.
  4. Reinstall the air filter and air filter cover.

Troubleshooting Techniques

If your lawn mower still doesn’t start after following the previous steps, there are a few troubleshooting techniques you can try:

1. Use a Fuel Stabilizer

If you frequently store your lawn mower with gas in the tank, it is recommended to use a fuel stabilizer. This additive helps prevent gasoline from deteriorating, extending its shelf life and reducing the formation of gum and varnish deposits. Follow the product instructions for proper usage.

2. Check the Spark Plug

A faulty or dirty spark plug can also prevent your lawn mower from starting. Remove the spark plug and inspect it for any signs of damage or carbon buildup. If necessary, clean or replace the spark plug to ensure a strong spark for ignition.

3. Clean or Replace the Air Filter

A clogged air filter can restrict air flow to the engine, affecting performance and starting. Remove the air filter and clean it using compressed air or replace it with a new one if needed.

4. Consult a Professional

If you have followed all the steps and your lawn mower still refuses to start, it may be time to seek professional help. Experienced technicians have the expertise and tools to diagnose and fix more complex issues that may be preventing your lawn mower from starting properly.

By understanding the effects of old gas on your lawn mower, properly preparing your mower, and utilizing troubleshooting techniques, you can successfully start your lawn mower with old gas. Remember to always follow safety precautions and consult your mower’s manual for specific instructions. With a little effort, you’ll have your lawn mower up and running in no time, ready to tackle your yard maintenance tasks.
