How to Start a Small Engine After Years: Revive your Engine

Starting a small engine that has been sitting for an extended period can be a daunting task. Whether it's a lawnmower, generator, or any other small engine-powered equipment, getting it up and running after years of inactivity requires careful attention and the right approach. In this guide, we'll explore the steps and precautions to take when facing the challenge of reviving a small engine that has been sitting idle for years.

Small engines left unused for an extended period often face challenges when it comes to starting. The primary reasons for all of these are stale fuel, deteriorated oil, corroded spark plugs, and clogged carburetors. These issues can prevent the engine from igniting and running smoothly

Before attempting to start a small engine that has been inactive for an extended period, it's essential to prioritize safety. Here are some safety precautions to keep in mind:

• Work in a well-ventilated area to prevent carbon monoxide buildup.
• Wear safety goggles and gloves to protect your eyes and hands.
• Ensure the engine is cool before starting any work.
• Disconnect the spark plug wire to prevent accidental starts.

Before attempting to start the engine, assess its condition. There are many things you can do

Inspect the Fuel and Fuel System

Check if your fuel tank has oil or not. Always consider this, because it’s such a simple thing, but many of us forget about it.

If there’s fuel, then check to see whether the fuel is old or stale. If the fuel smells bad or has visible contaminants, it's essential to drain it completely.

Checking the Oil

Examine the engine's oil level and condition. If the oil is dark, sludgy, or below the recommended level, it should be changed.

Examining Spark Plugs

Inspect the spark plugs for signs of corrosion or fouling. Damaged spark plugs should be replaced.

Follow these steps to successfully start a small engine that has been sitting idle for years:

Step 1: Fuel System Preparation

Drain the old fuel from the tank and fuel lines. Clean or replace the fuel filter if necessary. Refill the tank with fresh, clean gasoline.

Step 2: Oil Check and Change

Verify the oil level and quality. Change the oil if it's degraded or below the recommended level. Don’t forget to change the right kind of oil.

Step 3: Spark Plug Inspection and Replacement

Inspect the spark plugs for corrosion or fouling. Replace any damaged or worn spark plugs with new ones.

Step 4: Air Filter Examination and Replacement

Check the air filter for dirt and debris. Replace the air filter if it's clogged or damaged.

Step 5: Carburetor Cleaning

Clean the carburetor to ensure proper fuel and air mixture. Use carburetor cleaner and follow manufacturer guidelines.

Step 6: Fuel System Priming

Prime the fuel system by following the manufacturer's instructions. This step varies depending on the engine type and model.

Step 7: Crank and Start

Reconnect the spark plug wire. Crank the engine while following the starting procedure specified in the owner's manual. Once started, allow the engine to run for a few minutes to stabilize.

Starting a small engine after it has been sitting idle for years is a manageable task when you follow the right steps and precautions. By addressing issues related to fuel, oil, spark plugs, and the carburetor, you can breathe new life into your small engine-powered equipment and ensure it operates smoothly for years to come.

1. How often should I run my small engine-powered equipment to prevent starting difficulties?

It's advisable to run your equipment for a few minutes every month if it's in storage to prevent fuel system issues and maintain engine health.

2. Can I use the same oil in my small engine that I use in my car?

Small engines typically require specific small engine oil. Check your owner's manual for the recommended oil type and viscosity.

3. What is the shelf life of gasoline in a small engine's fuel tank?

Gasoline can start to degrade within a month. Using a fuel stabilizer can extend its shelf life for up to a year.

4. Why is priming the fuel system important when starting a small engine?

Priming the fuel system helps ensure that fuel reaches the carburetor and spark plug, making it easier to start the engine, especially after extended periods of inactivity.

5. How can I prevent corrosion in the fuel system of my small engine during storage?

Using a fuel stabilizer, draining the fuel system before storage, and keeping the equipment in a dry location can help prevent corrosion in the fuel system.
