Fixing Generator Surging: Step by Step Instructions

Generator surging is a common issue that many people encounter when using their generators. When you start up your generator and turn off the choke, you may notice that it starts to idle up and down erratically. This is known as generator surging and is often caused by debris clogging up the low-speed circuit in the carburetor. In this article, we will discuss how to fix a generator surging problem using three popular generator brands: Champion, Predator, and Westinghouse.

Understanding the Generator Surging Problem

What is Generator Surging?

Generator surging refers to the irregular or fluctuating idle speed of a generator when running. Instead of running smoothly at a constant speed, the generator may rev up and down in an inconsistent pattern. This can result in issues with power output and can even lead to the generator shutting off unexpectedly. Generator surging is most commonly experienced when the choke is turned off, and the generator is running at a lower RPM.

Common Causes of Generator Surging

Several factors can contribute to generator surging. The most common cause is a clogged or dirty carburetor, specifically, the low-speed circuit. Over time, debris, such as dirt, dust, and fuel residue, can build up and block the small openings in the carburetor, leading to improper fuel flow. Other potential causes include a malfunctioning fuel pump, a dirty air filter, or an issue with the spark plug.

Fixing Generator Surging: Step by Step Instructions

In this section, we will provide detailed instructions on how to fix the generator surging problem for the Champion and Predator generator models. Please note that these instructions may vary slightly based on the specific model and make of your generator.

Champion Generator

Removing the Throttle Stop Screw

To access the low-speed jet in a Champion generator, you will first need to remove the throttle stop screw that sits on top of the jet. Count the number of turns as you remove the throttle stop screw so that you can return it to its factory settings later.

Removing the Low-Speed Jet

Using a pair of pliers or a flat head screwdriver, carefully lift the low-speed jet out of its position. This small jet has a tiny hole that can easily get clogged with debris. Take a moment to observe the size of the jet hole, and you will understand why even the smallest piece of debris can cause surging.

Cleaning the Jet

To clean the jet, use a single strand of wire or a small piece of paper to clear any obstructions in the hole. Be gentle while doing this to avoid damaging the jet or enlarging the hole. Avoid using an air compressor as it can potentially damage the jet.

Reinstalling the Jet and Throttle Stop Screw

Carefully place the cleaned jet back into its position, ensuring that you do not damage the two o-rings on the jet. Align it properly and gently push it down until it clicks into place. Reinstall the throttle stop screw, tightening it to its seated position. Then, back it out to the number of turns you counted earlier, returning it to the factory settings.

Predator Generator

Accessing the Carburetor

Unlike the Champion generator, you do not need to remove the airbox to access the carburetor in a Predator generator. Simply press against the airbox with your hand from behind to create enough space to work.

Removing the Throttle Stop Screw

Similar to the Champion generator, remove the throttle stop screw while counting the number of turns it takes to remove it. This will allow you to return it to the original settings later.

Removing the Low-Speed Jet

Using pliers, carefully lift out the low-speed jet, which is located in a similar manner to the Champion generator. Take note of the tiny hole in the jet, which can easily become clogged with debris.

Cleaning the Jet

Using a single strand of wire or a small piece of paper, clean the jet by gently clearing any blockages in the hole. You can also use carburetor cleaner to assist in the cleaning process. However, avoid using an air compressor as it may cause damage.

Reinstalling the Jet and Throttle Stop Screw

After cleaning the jet, place it back into its position, being mindful of the o-rings. Line it up as it was before and push it down until it clicks. Reinstall the throttle stop screw, tightening it to its seated position. Then, back it out to the original number of turns you counted earlier.

Testing the Fixed Generator

After following the above steps to fix the generator surging problem, it is essential to test the generator to ensure that the issue has been resolved. Start the generator and observe its idle speed. It should now run smoothly without any erratic fluctuations. Test the generator in both the eco mode and regular mode to verify that it operates correctly in both settings.

Conclusion

Generator surging can be a frustrating problem, but with proper maintenance and cleaning of the carburetor, it can be resolved. By following the step-by-step instructions provided in this article, you can fix the generator surging problem in popular brands like Champion and Predator. Remember to exercise caution when removing and reinstalling components, and always refer to the manufacturer's instructions for your specific generator model. Enjoy uninterrupted power supply from your generator by ensuring it is well-maintained and free from surging.
