Carburetor basics
Before we get into the steps of cleaning a carburetor, it’s important to understand what a carburetor does and why it needs to be cleaned. A carburetor is responsible for mixing fuel and air in the right proportions so that the engine can run properly. Over time, dirt and debris can build up in the carburetor, causing it to run less efficiently. When this happens, it’s time to clean the carburetor.
What are the basic parts of carburetors?
There are four basic parts to every carburetor: the air intake, the throttle plate, the fuel jet, and the float chamber. The air intake allows air to enter the carburetor, while the throttle plate controls how much air enters. The fuel jet controls how much fuel is drawn into the carburetor, and finally, the float chamber holds a small amount of fuel so that the engine can continue to run even when the mower is tilted.
Why you need to clean the carburetor
There are a few reasons why you might need to clean your carburetor.
- If your lawn mower has been sitting for a while, the fuel in the carburetor can start to break down and form a gum-like substance. This can clog up the carburetor and prevent it from working properly.
- If you use your lawn mower in dusty conditions, dirt and debris can also build up in the carburetor, causing it to run less efficiently.
- If you use ethanol-based fuel, it can also cause problems in the carburetor over time. Ethanol is a solvent that can break down parts of the carburetor, causing it to run less efficiently.
Why is a carburetor important?
Over time, mixing the air and fuel in the correct ratio for combustion can become gummed up or dirty. This causes your law mower to run less efficiently. If left uncleaned, a dirty carburetor can eventually lead to engine failure.
If you don’t regularly clean your carburetor, it can cause a number of problems.
- A dirty carburetor can cause your engine to run rough.
- A dirty carburetor can cause your engine to stall.
- A dirty carburetor can cause your engine to misfire.

All of these problems can be avoided by regularly cleaning your carburetor.
