How To Clean A Carburetor On An Inverter Generator

The key to any smooth-running engine is a well performing carburetor. If your inverter generator won’t start, one of the reasons why could be a dirty carburetor. It’s important to keep this essential feature clean, as this will hinder the overall performance of your generator. 

In this video, our warehouse team demonstrates a step-by-step guide on how to clean the carburetor in your inverter generator. 


Cleaning the carburetor does not require fancy tools and equipment. As shown in the video, we use an ultrasonic jewelry cleaner along with an ultrasonic cleaning powder to get the job done effectively. 


  1. Disassemble the generator housing.
  2. Remove the air filter. 
  3. Remove the air filter backing to easily access the carburetor. 
  4. Loosen all screws holding the carburetor in. 
  5. Carefully remove all connecting springs and fuel lines. 
  6. Slide carburetor off. 
  7. Remove the air lines connected to the carburetor. 
  8. Disassemble all parts of the carburetor for a thorough cleaning. (This is not required, but recommended.) 
  9. Mix in the ultrasonic cleaning powder into the water and place the carburetor inside for at least 90 seconds. 
  10. Once cleaned, dry off all parts and reassemble. You may use a spray dryer along with a towel. 
  11. Assemble the carburetor, ensuring that the cover is aligned correctly. 
  12. Connect fuel lines on the generator. 
  13. Carefully slide the carburetor back in firmly, avoiding any air spaces. 
  14. Reassemble all parts of the carburetor, such as the throttle and electronic lines. 
  15. Tighten bolts and screws. 
  16. Weave in the spring for the electrical line on the throttle and secure tightly. 
  17. Attach air lines back onto the carburetor. 
  18. Attach air filter backing. 
  19. Tighten all screws and bolts holding the air filter cover in place. 
  20. Assemble the air filter. 
  21. Assemble the inverter generator housing. 

    Pro Tip: When disassembling the carburetor, mark the top and bottom with a colored marker to ensure proper alignment for reinstallation. 

    Once your carburetor is cleaned, make sure that you are using only clean fuel. Avoid using liquids such as ethanol, as it can cause corrosion and damage. 

    While the carburetor is not always the cause of a dysfunctioning generator, more than often, it is the main culprit. Stay on top of any defects and keep your inverter generator running at it’s best by maintaining a clean, healthy carburetor.
