cleaning a carburetor in 8 easy steps! - air cleaner in car

The carburetor is the most common problem in all small engines.
The carburetor is where the fuel is mixed with the air to burn.
Almost all types of internal combustion engines are equipped with a carburetor.
When the engine does not run for a long time, the fuel starts to break down.
After cleaning the carburetor, make sure to replace the fuel in the tank before starting the engine, otherwise you will re-create the trouble.
The carburetor cleaned in this way is on the old motorcycle and looks like most of the other carbs on the motorcycle or ATV.
While most carburetor looks different from the one shown, they still have most of the same features and layout.
Tools Needed: Phillips screwdriver flat head screwdriver needle swierswire brush wrench or socket kit supplies required: carbohydrate and choke cleaner and part cleaner (optional)
Washer set or carb reconstruction kit (recommended)
Figure 1: The first step for the carburetor to take off is to close the fuel valve on the fuel tank.
Trace the fuel line down to carbs and remove the hose. (
If the line is old and broken, you will want to replace the hose to make sure there is no leakage. )
There will also be overflow hose in the carburetor, also remove this hose.
Next, loosen the screws in the front and back clips of carbs.
The carburetor should be loose;
You should be able to twist the carbs to remove it.
Carbs will be held through the throttle cable.
The throttle is closed by screwing the cover.
When you screw it off and it falls off the slide, it will still be attached to it.
Carbs should be removed now.
Figure 2: After removing carbs, you need to remove the oil door slider from the cable (
Still attached to the vehicle).
This can be a daunting task, but the picture shows the completion of the display part.
After unplugging the cable, you can remove everything from the cable and there should be parts in the picture.
Picture 1: The float is the bottom of the carburetor, the first thing to be taken apart when cleaning carbs.
To remove the float bowl, unscrew the four screws at the bottom of the carburetor.
Remove these screws carefully as they are very easy to peel off.
The floating bowl can then be removed from the carbs.
Do not tear the washer if you do not change it.
The problem of cleaning the parts will be solved later, so do not start cleaning.
Figure 2: pull the floating pin out with a pair of needle and nose tongs and remove it.
After the pin is removed, the float can be removed.
In some carburetor, the needle will hang on the float and come out with it.
This is not the case in this carburetor, so some steps will fail.
Picture 1: This step will vary from carbs to carbs, but the spray needs to be removed.
In this carbs, there are some splash plates that need to be removed, not all of them.
The jet is a screw that has a hole through its center, and the fuel is mixed with air through the hole.
Plates need to be removed in order to get to the jet.
The main jet is short and fat;
There will be a hexagonal head or a flat screw head.
The pilot jet is long and thin and needs to be disassembled with a flat screwdriver.
The jet can be seen in Figure 2.
Figure 2: On this carburetor, the float needle is held by the fuel splash board.
Remove this plate so that the float needle can be removed to clean.
Figure 1: The last step before cleaning carbs is to remove the last part from the outside.
The air screw and idle screw can be removed with a flat head screwdriver.
They are located on the side of carbohydrates.
Idle screw is the larger screw to adjust idle speed when the engine is idle.
Figure 2: remove the air screw.
The air screw is a smaller screw that adjusts the air flow through carbohydrates when the engine is running.
Figure 3: remove the choke if it is possible to remove it from the carburetor.
Turn the top with a wrench and the choke is like a slip out.
Image 1: clean carbs and parts remove all washers and O-RINGS.
The easiest way to clean the carburetor and parts is to soak them in a gallon of carbs and part cleaners, but this can is very expensive to use only once.
Clean according to the instructions on the can.
Parts can also be cleaned by spraying carbs and choking cleaners.
Picture 2: Be sure to wear safety glasses. it is recommended to wear gloves for cleaning.
The parts should be scrubbed with a brush and then sprayed with carbs and choking detergent.
Spray the cleaner into the holes from the nozzle, air and idle screw, float needle and choke.
When cleaning the nozzle, be sure to spray detergent into the hole.
To make sure the nozzles are clean, please observe them through the light to make sure the holes are cleaned.
If the nozzle is not completely cleaned, blowing compressed air through the hole will remove the remaining debris.
Figure 3: Make sure all debris is removed from the carburetor.
The easiest way is to dry the carburetor and all the components with compressed air.
Blow the compressed air into all the holes and blow off all the parts of the carbs.
After everything is done, install the new o-
If you have rings and washers, the old ones can be reused if not.
Install the part in reverse order of removing the part.
In this case, the float needle and the fuel splash board are installed first.
Jet planes and splash boards were installed next.
Figure 1: install the external components of the carburetor first.
Start with the choke first, then the air screw and the idle screw.
When installing air screws (
Thin screws)
, Screw all the way, and then screw out a half circle.
This is the baseline and you can adjust it after the engine is running so that the engine works properly.
The idle screw should be screwed into a position sufficient to accommodate it.
Baseline adjustments will be made in subsequent steps.
Then install the float.
To install the float, align the hole with the hole in the carburetor and slide the float pin in.
The pin slides freely, just make sure it's centered so it's safe.
To ensure that the floating needle works properly, move the floating needle up and down to ensure that the needle moves freely.
If the needle is stuck in an upward position, it needs to be replaced.
Image 2: install the floating bowl to carbs with 4 screws at the bottom.
Carbs should now be complete without the throttle.
Image 1: Slide the throttle back and install it on the throttle cable.
Pass the throttle cable through the upper cover of the carbs and open the spring.
Place the needle in the slide, compress the spring, and hook the end of the cable to the slide.
Before sliding the slider into the hole, make sure that the slot in the slider is aligned with the idle screw.
As they line up, slide the throttle into and screw the lid on the top.
To set the baseline of the idle screw, look down at any of the holes in the carb and screw the idle screw in.
When the slider starts to rise, screw in half a circle.
Picture 2: Slide, shake and put the carbs back in the rubber boots.
Tighten the screws on the clip to secure the carbs in place.
Install the fuel line and overflow line on the carbs.
The final step of the project is to adjust your air and idle screws and the engine has to run in order to do so.
If you want to increase the idle speed, screw the idle screw in.
Screw the air onto richen and tilt.
