On older vehicles, a smooth-running carburetor is paramount in maintaining the right fuel-air mixture to keep your vehicle functioning properly. Regular inspection and cleaning is a great way to ensure this.
Time between cleanings can vary depending on individual driving habits, but should be done about every time the oil is changed.
The addition of fuel additives can help to keep the fuel system clean and the carburetor flowing effectively.
Change your fuel filter on a regular basis to prevent debris from entering the carburetor.
