mixes fuel and air

The carburetor on a petrol engine has the job of mixing the fuel and the air at the correct rate for the engine speed/revs.
Air is sucked first through the air filter then into the carb through a ventury (Small gap) which once it has passed through creates a vacuum the other side of the ventury, this in turn atomises the fuel which mixes with the air and is sucked into the cylinder and is then ignited by the spark plug, what is left and the gases that are produced are pushed out of the exhaust valve and into the exhaust.
The harder you put your foot on the throttle the large the opening is in the carb, thus the more air it sucks in and the fuel it takes with it, and so on and so on...................

The carborator puts a certain amout of fuel in to the engine, along with a certain amount of air.but if the car isn't running and you keep pushing the gas peddal up and down a whole bunch of times you will flood it.but if it's a fuel injection kind that will not flood it and you won't have to pump the gas a couple of times before you start it when it's cold out.

The goal of a carburetor is to mix just the right amount of gasoline with air so that the engine runs properly. If there is not enough fuel mixed with the air, the engine "runs lean" and either will not run or potentially damages the engine. If there is too much fuel mixed with the air, the engine "runs rich" and either will not run (it floods), runs very smoky, runs poorly (bogs down, stalls easily), or at the very least wastes fuel. The carb is in charge of getting the mixture just right.

It delivers a measured amount of fuel and air to the engine. It is controlled by the throttle, normally called the gas pedal. The gas pedal is the only thing a non mechanical person should touch.

mixes the fuel to air to go into the cylinders to make the cars engine work

it manages the air and fuel that the car needs to run

supplies fuel to the engine in a roundabout kind of way. most modern cars don't have one though as they are fuel injection.

it mixes petrol with air but modern cars have fuel injection system replacing it
