How to Fix a Generator: Step-by-Step Maintenance Guide

Generators are an essential piece of equipment when it comes to providing backup power. However, like any machinery, generators require regular maintenance to ensure they perform optimally. In this guide, we will walk you through the process of fixing a generator that has been sitting idle or experiencing various issues. From addressing cracked fuel lines to fixing a non-functioning on/off switch, we will cover all the necessary steps to get your generator back up and running.

The Problem: Generator Maintenance

Before we dive into the maintenance process, it's important to understand the common issues that generators can face after a period of inactivity. These problems often include cracked fuel lines, non-functioning switches, and melted parts due to prolonged exposure to heat.

Lack of Use

Generators that have sat idle for a long time are prone to various issues. Fuel can go bad and clog the system, while parts may deteriorate due to lack of lubrication and movement.

Cracked Fuel Lines

One of the most common problems with generators is cracked fuel lines. Over time, the fuel lines can degrade, resulting in fuel leakage and improper functioning of the generator.

Non-functioning On/Off Switch

If the on/off switch of your generator is not working properly, it can be a hassle to start or stop the unit. This can often be caused by loose connections or electrical faults.

Melted Parts

Generators generate a significant amount of heat during operation. If certain components, such as wires or plastic parts, are exposed to excessive heat, they can melt and affect the overall functionality of the generator.

Initial Assessment: Getting Started

Before diving into the maintenance process, it's essential to evaluate the condition of the generator and gather the necessary tools. Here are the first steps you should take:

  1. Removing the Gas: If your generator has been sitting for a while, start by removing the old gas. This can be done by using a battery-operated pump or siphoning the gas out manually.

  2. Opening the Generator: Once the gas is removed, you can begin inspecting the internal components of the generator. This typically involves removing the cover using basic tools such as a screwdriver.

  3. Cleaning the Carburetor: The carburetor is a crucial component of the generator's fuel system. It controls the flow of fuel and air, ensuring proper combustion. Cleaning the carburetor can help resolve issues related to fuel delivery and start-up.

The Carburetor: Key Component of a Generator

The carburetor plays a vital role in the proper functioning of a generator. Let's take a closer look at how it works and the steps involved in cleaning it effectively.

Understanding the Main Jet

The main jet is responsible for regulating the amount of fuel flowing into the carburetor. It can become clogged or blocked over time, leading to poor fuel delivery and inefficient generator performance.

Cleaning the Needle and Seat

The needle and seat control the flow of fuel into the carburetor bowl. Cleaning them ensures that fuel can flow freely and be properly mixed with air for efficient combustion.

Using Torch Tip Cleaner

One effective tool for cleaning the tiny holes in the carburetor is a torch tip cleaner. This small tool allows you to remove any built-up debris and ensure the smooth flow of fuel.

Cleaning and Reassembling the Carburetor

Once you have removed the necessary components from the carburetor, it's time to clean and reassemble it. This step is crucial for restoring the proper functioning of the generator.

  1. Removing and Cleaning the Motion Tube: The motion tube is responsible for the movement of fuel through the carburetor. Cleaning it ensures that fuel can flow smoothly without any blockages.

  2. Cleaning All Tiny Holes: The carburetor contains various tiny holes that can become blocked over time. It's important to clean each hole meticulously to ensure optimal fuel delivery.

  3. Cleaning the Pop-off Valve: The pop-off valve prevents excess pressure buildup in the carburetor. Cleaning it will ensure that it functions properly and prevents potential damage.

Fuel System Maintenance

As a generator owner, it is crucial to maintain the fuel system to prevent problems such as fuel leaks and clogged lines. Here are the steps involved:

  1. Replacing Cracked Fuel Lines: Carefully inspect the fuel lines for cracks or signs of damage. Replace any damaged lines to prevent fuel leakage.

  2. Choosing the Right Size Fuel Line: When replacing fuel lines, ensure that you select the correct size to ensure proper flow and prevent leaks.

  3. Proper Installation of New Fuel Line: Install the new fuel line carefully, ensuring a secure connection between the carburetor and the fuel tank.

Changing the Oil

Regular oil changes are essential for the longevity and performance of your generator. Here's how you can change the oil in your generator:

  1. Removing the Old Oil: Locate the oil drain plug at the base of the generator and use a wrench to loosen it. Allow the old oil to drain completely.

  2. Choosing the Right Oil for Your Generator: Check the manufacturer's recommendations to determine the appropriate type and viscosity of oil for your generator.

  3. Refilling the Oil: Pour the recommended amount of oil into the oil fill port, ensuring not to overfill. Use a dipstick to check the oil level and add more if needed.

Replacing the Spark Plug

A faulty spark plug can lead to issues with starting and running your generator. Replacing the spark plug is a straightforward process:

  1. Removing the Old Spark Plug: Use a spark plug socket and a ratchet wrench to loosen and remove the old spark plug from the engine block.

  2. Selecting the Correct Spark Plug: Refer to the generator's manual to identify the correct spark plug model for your specific generator.

  3. Installing the New Spark Plug: Carefully insert the new spark plug into the engine block and tighten it using a spark plug socket and ratchet wrench.

Testing and Final Steps

After completing the necessary maintenance tasks, it's essential to test your generator to ensure that it is functioning correctly. Here's what you should do:

  1. Turning on the Generator: Start the generator and let it run for a few minutes to ensure that it starts smoothly and runs without any issues.

  2. Checking for Any Remaining Issues: Observe the generator for any abnormal sounds, leaks, or other issues. Address any additional problems that may arise during the testing process.

  3. Maintenance Tips for Future Use: Provide your generator with regular maintenance to avoid future problems. This includes changing the oil regularly, checking the spark plug, and inspecting the fuel system for leaks or cracks.


Maintaining and fixing a generator doesn't have to be complicated. By following the step-by-step process outlined in this guide, you can ensure that your generator continues to provide reliable backup power whenever you need it. Regular maintenance and prompt repairs will extend the life of your generator and save you from unexpected power outages. Take the time to keep your generator in top shape, and it will be ready to serve you whenever you need backup power.
