Finding the Old Generator

The author recounts stumbling upon an old generator while driving home from work. The generator had been discarded on the side of the road, seemingly left for garbage pickup. The author noticed that it was a Champion 196cc 4,000-watt non-inverter style generator, similar to a Honda model. Despite its age and the fact that it had been sitting unused for a long time, the author saw the potential to bring it back to life.

The Problem with Stale Fuel

One of the main reasons why people often throw out old generators is because they have trouble starting. This is usually due to the fuel going bad after sitting for an extended period. The author examines the generator and discovers that the gas in the tank has turned into a stinky, rotten mixture. Stale fuel is particularly problematic for high compression engines like the one in the generator. This presents the first challenge in getting the generator to run again.

Taking Apart the Carburetor

To fix the issue with stale fuel, the author decides to take apart the carburetor and clean it thoroughly. They provide a step-by-step guide on removing the airbox, cover, and bolts to access the carburetor. The author emphasizes the importance of being gentle and cautious during this process to avoid damaging the gasket or the spring connected to the governor link rod.

Cleaning the Carburetor

Once the carburetor is disassembled, the author demonstrates the various components that need to be cleaned. They identify the main jet, emulsion tube, and idle jet as the main areas where debris and gel buildup can occur. The author mentions the necessity of using premium fuel without ethanol in small engines like the generator to prevent such issues. They recommend using an ultrasonic cleaner to thoroughly clean the carburetor and its parts.

Other Parts that Need Cleaning

Apart from the carburetor, the author highlights the importance of cleaning other components that can contribute to starting issues. They mention a tube in the carburetor that can become clogged, causing fuel flow problems, as well as an additional jet located underneath the idle speed screw. The author suggests using a piece of bicycle brake cable or guitar string to clear any blockages in these components.

Putting the Carburetor Back Together

After cleaning all the necessary parts, the author reassembles the carburetor. They demonstrate how to properly position the float pin and attach the fuel line and throttle rod. The author also mentions performing an oil change and cleaning out the fuel tap's sediment bowl as part of the maintenance process.

Checking the Oil and Fuel

Before attempting to start the generator, the author ensures that there is enough oil in the engine and that fresh fuel has been added to the tank. They emphasize the importance of using quality fuel without ethanol to prevent future issues.

Starting Up the Generator

After completing all the cleaning and maintenance tasks, the author is ready to test if the generator will run. They showcase the on/off switch and the choke lever and proceed to start the generator. Fortunately, the generator starts up successfully, indicating that it is in good working condition.


In conclusion, this article serves as a helpful guide for anyone who finds an old generator and wants to revive it. By following the step-by-step instructions provided, readers can learn how to troubleshoot and fix common issues that arise when a generator has been sitting unused for a long time. With a little bit of TLC and some basic maintenance, an old generator can be brought back to life and potentially sold for a profit.

Q: How often does fuel go bad in a generator? A: Fuel can start to go bad within just a few months if it contains ethanol. Without the use of fuel stabilizers, it can become stale even faster.

Q: Can a generator be damaged by using stale fuel? A: Yes, using stale fuel in a generator can cause starting issues and potentially damage the engine. It is important to use fresh, high-quality fuel.

Q: What other maintenance tasks should be performed on an old generator? A: Apart from cleaning the carburetor, it is crucial to check the spark plug, air filter, and fuel filter. These components may need cleaning or replacement to ensure optimal performance.

Q: How long does it take to clean the carburetor using an ultrasonic cleaner? A: The duration of the cleaning process can vary, but typically 25 to 30 minutes is sufficient to remove debris and gel buildup from the carburetor components.
