How I Fixed My Onan 4000 Generator

Introduction

In this article, I will share my experience and provide a step-by-step guide on how I fixed my Onan 4000 generator. I encountered a problem with the carburetor and found a unique and cost-effective solution that I want to share with other generator owners. I will explain the process of replacing the factory carburetor with an aftermarket one and provide tips and tricks to ensure a successful installation. If you're facing similar issues with your Onan 4000 generator, this article is for you.

Problem with Carburetor

As a generator owner, you may have experienced carburetor-related problems, especially if the generator has been sitting unused for some time. Over time, the fuel can gum up in the carburetor, causing it to malfunction. The traditional solution is to replace the factory carburetor, which can be quite expensive. Furthermore, during the COVID-19 pandemic, finding and purchasing Onan parts became even more challenging and costly.

Aftermarket Carburetor Solution

To avoid the high cost of a factory carburetor, I decided to explore alternative options. After extensive research, I discovered an aftermarket carburetor available on Amazon for only $60. This solution proved to be affordable and efficient. What surprised me the most was the fact that not many people had shared this solution or the installation process on YouTube or other platforms.

Solenoid Adjustment

During the installation process, I encountered a flooding issue with the new carburetor. However, I identified the problem and found a simple adjustment to fix it. There is a solenoid located near the carburetor that controls the fuel flow. By adjusting the needle valve inside the solenoid, I was able to regulate the amount of gas entering the carburetor, resolving the flooding problem.

Tips for Installing the New Carburetor

Installing the new carburetor is relatively straightforward, but there are a few tips that can make the process easier. First, you don't need to remove the entire old carburetor. Instead, only the bowl cover needs to be replaced with the new one. This saves time and effort while still resolving the carburetor issues. Additionally, using an extension on the wiring harness can make plugging and unplugging the solenoid much easier.

Benefits of Using Aftermarket Parts

Using aftermarket parts, such as the carburetor in this case, offers several benefits. The most obvious advantage is the significant cost savings compared to factory parts. Aftermarket parts are often more affordable while providing similar or even better performance. Moreover, the availability of aftermarket parts is generally higher, even during difficult times like the COVID-19 pandemic.

Pros and Cons of Replacing the Carburetor

Replacing the carburetor with an aftermarket one has its pros and cons. On the one hand, it offers a cost-effective solution to fix the generator, saving you from spending hundreds of dollars on a factory carburetor. On the other hand, some may argue that aftermarket parts might not offer the same level of quality and durability as original parts. It is essential to weigh these factors when making a decision.

Conclusion

If you're facing issues with your Onan 4000 generator's carburetor and don't want to spend a fortune on a factory replacement, consider the alternative solution provided in this article. Replacing the carburetor with an affordable aftermarket option can save you both time and money. By following the installation tips and adjusting the solenoid correctly, you can bring your generator back to life at a fraction of the cost.
