In practice, finding the correct air and Carburetor Float mixture will help extend the life of your engine. If your engine is running too rough, it's important to adjust the mixture and find the correct idling speed to decrease engine stress, keeping things from running too fast or too slowly. Actually, adjusting the carburetor in your car can be done with just a few simple steps and no special tools. Read the following article for more information.

Firstly, you need to locate the air filter and remove it. On most cars, you'll need to remove the air filter to expose to carburetor and adjust it. Open the hood and make sure the engine is off before locating the air filter and removing the assembly. Unscrew the wing-nut and any other connectors, and then remove the air filter entirely.

Generally, the air filter could be in any number of different places on the engine depend on different models and engines. However, on most carbureted cars, the air cleaner housing is attached directly to the carburetor.

Secondly, you are going to find the adjustment screws on the front of the carburetor. There should be two screws on the front of the carburetor, which are used to adjust the air and fuel mixture. Usually, these screws look like flat-head screws and you can use a screwdriver to turn them, adjusting the amount of fuel and air mixing in the carburetor. But some carburetors may have a special screw and require a specific adjusting tool. Look to your own model, and you should choose the right tools to help you.

Then, the next step is to start the engine and let it warm to normal operating temperature. Check the temperature gauge to know when it is at the appropriate running temp, and listen to the sound of the engine to get some sense of the adjustments that need to be made. In general, an engine that runs lean will ping at higher RPM, when the throttle is open, it seems you were flooding a gear. So more gas need to be added to the mixture. On the other hand, an engine that runs rich will not necessarily make a change in sound, but you'll be able to smell it. Bring the gas down some. Because an engine that runs too rich at idle will cause the plugs to be fuel-fouled, leading to a vehicle that is harder to start cold.

Now, its time to adjust both screws equally and find the right mixture. Adjusting the Carb Needle is a lot like tuning a guitar or other stringed instrument. You want to turn the screws equally, smoothly, and slowly until you find the sweet spot. Regardless of whether or not the engine is running too rich or too lean, bring it down to a very lean mixture by turning both screws a quarter-turn at a time, counter-clockwise, then slowly bringing them back up to an equal and smooth mixture. As a matter of fact, adjusting the mixture is an imprecise art, just requiring that you know your engine well and listen close. Bring both screws up slowly and listen until the engine purrs smoothly. Any raggedness or rattling is a sign of too lean a mixture. Keep turning until you find the sweet spot. Finally, you need reassemble the air filter. When you've got the carburetor adjusted, put the air filter back on and you're ready to roll.Read more to zjautoparts.net.
