Carburetors

Clean and adjust a carburetor with confidence

A dirty carburetor is one of the most common reasons small engines run badly or not at all. This section explains what a carburetor does, how to recognize the signs of gummed-up jets and how to clean or rebuild one carefully. You will also learn about float levels, fuel bowls and basic adjustments. Take photos as you disassemble, keep small parts organized and work in a ventilated space away from sparks. If the problem returns, consider replacing the carburetor.
