How to Fix Surging on a Generator

Generators are essential machines that provide power during emergencies or in areas with limited electricity access. However, they can experience issues like surging, which can disrupt their smooth operation. Surging occurs due to factors like bad fuel or a clogged carburetor. If you're facing surging issues with your generator, this article will guide you through the steps to fix it.

1. Introduction

In this article, we'll discuss how to stop the surging on a generator, specifically focusing on Westinghouse generators. However, the techniques shared here can be applied to any generator that exhibits surging issues.

2. Understanding the Surging Issue

Before diving into the fix, it's important to understand what causes surging in a generator. Surging refers to the erratic fluctuations in engine speed that can make the generator sound unstable. One common cause of surging is bad fuel, which can lead to clogs in the carburetor. By eliminating the bad fuel and cleaning the carburetor, you can resolve the surging issue.

3. Evacuating the Fuel

The first step in fixing the surging issue is to evacuate all the old fuel from the generator. This can be done using a fuel transfer pump, which efficiently drains the fuel into a separate gas can. Ensure that you use a high-quality fuel transfer pump to ensure a quick and clean evacuation process. Once the fuel has been evacuated, dispose of it properly or use it in a vehicle.

4. Cleaning the Carburetor

The carburetor plays a crucial role in the proper functioning of a generator. If it becomes clogged, it can contribute to the surging problem. Here's how you can clean the carburetor to resolve the issue:

4.1 Accessing the Carburetor

To access the carburetor, you may need to remove some tubes and components. Carefully remove these parts to gain better visibility and access to the carburetor. Take note of the components you remove to ensure proper reinstallation afterward.

4.2 Using Carburetor Cleaner

Using a carburetor cleaner, spray the cleaner into the carburetor throat while covering one hole with your finger. This will help clear any blockages and ensure smooth airflow. Continue spraying the cleaner in different areas of the carburetor to thoroughly clean it.

4.3 Brushing the Pilot Idle Jet

Using a small brush, clean the pilot idle jet, which is a common area for clogs. The brush should be able to reach into the small holes and remove any debris or buildup. Make sure to clean the jet carefully, as any residual blockage can contribute to surging.

5. Adjusting the Idle

After cleaning the carburetor, it's important to readjust the idle settings. The idle adjustment controls the engine speed when it's not under load. Fine-tune the idle adjustment until the generator runs smoothly without surging. This adjustment may vary depending on the specific model of the generator, so refer to the manufacturer's instructions for guidance.

6. Refueling the Generator

Once the carburetor has been cleaned and the idle adjusted, it's time to refuel the generator. Use fresh, high-quality gas to ensure optimal performance. Consider using a fuel transfer pump to avoid spills and efficiently fill the generator's fuel tank. Take care not to overfill the tank, as it can lead to fuel spills or other issues.

7. Testing the Generator

With the new fuel and carburetor adjustments in place, start the generator and listen for any signs of surging. Let the generator run for a few minutes to ensure that it operates smoothly without any fluctuations in engine speed. If the surging issue has been resolved, congratulations! Your generator is now ready for reliable power generation.

8. Conclusion

Fixing surging issues on a generator is relatively simple if you follow the right steps. By evacuating the old fuel, cleaning the carburetor, adjusting the idle, and refueling with fresh gasoline, you can eliminate surging and restore the smooth operation of your generator. Remember to always refer to the manufacturer's instructions for specific guidance and safety precautions.

FAQs

Q: Can bad fuel cause surging in a generator? A: Yes, bad fuel is one of the common causes of surging in generators. It can lead to clogs in the carburetor, resulting in unstable engine speed.
