When to Clean a Car Carburetor

We all know that cleaning a car carburetor is essential, so when it is the right time to give it a fresh outlook? We gathered here 4 signs for car owners to notice that it is the high time to clean the heart of the vehicle:

Your Engine Runs Lean

Nevertheless, if there is something shifting the ratio like too much air or low in fuel, your car will sound popping or sneezing. These sounds are also the signal for drivers to go clean their dear vehicles. Another case is that your engine’s fuel is being covered and blocked by dirt.  

Your Engine Runs Rich

On the other hand, “running rich” means the ratio of fuel and air is also not balanced, but in the opposite way. There is more fuel and low air in this ratio. In other words, “running lean” is the total opposite of “running rich”. In this situation, your car will emit black smoke from the exhaust, which can be recognized quite easily.    

Your Automobile Does Not Start

This is by far one of the most common reasons why you need to clean a car carburetor, since a dirty carburetor affects the engine’s performance. The explanation for this is that your vehicle is having too much dirt. The dirt prevents the passage of air as well as fuel into the engine. This will stop your car from running or starting. So it is time to clean the carburetor. 

Flooded Engine

Last but not least, too much dirt gathering in the fuel bowl tells drivers to clean the car carburetor. This situation causes blockage to the valve of the needle, which makes it impossible to close. As a consequence, the fuel will overflow into the carburetor, flow out of the bowl vents and cause a flooded engine. When this happens, the ratio between air and fuel will be messed up. Not to mention, this wets the spark plugs. When this occurs, car owners must clean the excess debris first before doing anything else.
