How to Clean Carburetor Lawn Mowers Clebran
Carburetor injection, being an outdated system compared to an injector, is still a fairly common ICE power scheme. Today, carburetors are found mainly on cars of domestic production and old foreign cars, which continue to be actively used in the CIS. Quite common malfunctions that a driver may encounter are cases when there is a problem with idling on a carburetor car, the engine does not start, it is unstable or stalls while driving, in transient conditions, etc. There are also jerks, failures during acceleration, the engine troits and consumes fuel a lot.
In other words, continuing to drive the car fails. The reason is the need to clean the carburetor, which tends to clog over time. In this article we will talk about how to clean the carburetor and how to clean the carburetor without removing it from the car. This can be especially useful when cleaning the carburetor is urgently needed in the field, the machine is far from service centers, etc.
How to clean the carburetor without removing
First of all, each owner of a carburetor car should have and always carry with him a special spray spray for cleaning the carburetor (the so-called “carbliner”). In some cases, it is enough to just remove the air filter cover and spray the carburetor with a cleaner on the device, after which the engine will normalize. Note that this approach does not always help to clean the carburetor channel, but sometimes gives results. Let’s take a closer look at this kind of cleaning.
- In addition to the aerosol can with the cleaning composition indicated above, you will need keys to remove the air filter cover;
- Having removed the filter housing, it may be necessary to unscrew the solenoid valve of the carburetor or the plug-holder of the fuel nozzle, which is responsible for idling (which depends on the design of the dosing device);
- After unscrewing, we get access to the hole in the carburetor cover. Through this hole, the cleaner can be fed to clean the channels of the idle system, as well as the transition system of the first chamber.
- In parallel, the carbikliner should be sprayed into the first and second chambers, as well as injected into the openings of the channels of the GDS air jets (main dosing system).
- The correct application of aerosol is considered to be when the agent is applied to the walls of the chambers and diffusers themselves, and the air and throttle are also processed. A nozzle in the form of a thin tube, which comes with the canister of the cleaner, allows you to process the most inaccessible elements.
- In addition, the cleaner should be sprayed to the place where the carburetor device has an air damper lever and a first chamber throttle actuator, other levers and accessible drive elements. This allows you to remove dirt from the controls, which ensures the normal operation of the carburetor injection.
- After applying the cleaner, pause for about 5 minutes. During this time, the product softens deposits and flushes dirt;
- Now the engine can be started. After starting, by pulling out the “suction” handle (this will allow the engine to work at idle without an electromagnetic valve), it should also be slightly gassed.
- Some drivers also forcibly increase their revolutions above XX, after which, on a engine operating at higher revolutions, the cleaner is additionally sprayed into the carburetor chambers, into the openings of the air ducts of the GDS, and also into the place of installation of the electromagnetic valve;
- After this, you can blaze again, then the cleaning procedure is repeated 2-3 times. The final step can be considered the installation of an electromagnetic valve or plug in place, after which the suction handle is retracted.
In other cases, cleaning the device with only one cleaner indiscriminately does not work. The fact is that garbage, as a rule, accumulates in the carburetor’s float chamber. As a result, the nozzles become clogged and the air supply channels become clogged. At the same time, the answer to the question whether it is possible to clean the carburetor without removing and parsing will still be in the affirmative.
Quick carburetor cleaning without cleaner
To accomplish the task, it is necessary to use the well-known method of cleaning the carburetor, which consists in the fact that two candle high-voltage wires are interchanged (for example, the wire from the first cylinder is placed on the 4th cylinder, and the wire from the 4th cylinder to the first). Then the motor can be started. The power unit will start, but the engine will “shoot” and “sneeze” into the carburetor. Such a rearrangement allows you to knock garbage from clogged nozzles back into the float chamber.
This is due to the fact that after starting the engine with rearranged wires, the synchronization of ignition is violated and a certain pressure will be created from untimely ignition of the mixture in the combustion chambers. Having cleaned the dosing system in this way, the high-voltage power wires should be put in place and the operation of the internal combustion engine should be checked. In many emergency cases, this cleaning method allows you to reach the place of repair by car.

For the procedure, you need to know how to clean the carburetor, disassembling the device. It should also be noted that after cleaning, additional adjustment of the carburetor, which must be performed by an experienced master, may be required.
What is the result
In view of the foregoing, it becomes clear that even with the relative simplicity of the design, the carburetor still needs timely additional care. To maintain the cleanliness and operability of the device, some experts recommend cleaning and adjusting the carburetor at least twice a year. It is recommended to do this in the off-season, that is, before the onset of severe frost or heat. This measure allows you to maintain fuel consumption at an optimal level.
If noticeable dips are noted during pressing the gas pedal, then the carburetor cover is removed in parallel with the carburetor cleaning itself, after which it is necessary to pay attention to the atomizer of the accelerator pump. This element should be thoroughly cleaned with a carbicliner; additionally, it can be purged with air under pressure from the compressor.
In other situations, it is better to disassemble and clean the dosing device as soon as possible. This statement is also true if the carburetor is very dirty for any reason or it has never been cleaned before.
