Removing a carburetor from a trimmer for Echo grass.

Cleaning a trimmer carburetor for grass: a detailed description of the process

All black cutters and trimmers for grass with a gasoline engine operating on gasoline have in their design such an important element as a carburetor. Outwardly, this is a small aluminum design, which is connected to the cylinder-piston group through the heat-resistant gasket. The detail plays a very important role, and in the event of a malfunction, the tool will work with interruptions or will not start at all. If the adjustment does not solve the situation, it is necessary to clean the carburetor of the trimmer for the grass. Each master can do this on his own, having at his disposal the necessary tools, materials and knowledge.

All lawn mowers and blacksmiths are equipped with two.stroke gasoline engines that cannot work without fuel mixture. It is worth noting right away that the trimmers use two.stroke gasoline engines that are of two types:

  • Two.stroke classic. their constructive features, as well as the principle of work, can be found here.
  • Modernized two-stroke engines are called 4-Mix. Their description, design and principle of action can be found in this material.

Normal carburetors are used on benzocoses, the device and principle of which are identical to chainsaws. The main difference between them. the presence of manual praying pages, which is called a primer. If you are interested in detailing in detail the question of how the gas cutter carburetor works and works, we recommend reading this article.

Knowing the device and principle of operation of the mechanism, you can understand the problem of cleaning. However, to begin with, we will find out why it is to clean it and whether such actions will help to solve the problem with the brown cutter.

If you read an article about the device and the principle of operation of a gas carburetor, then you already know that one of the main elements is a rubber membrane. It is this detail that makes fuel enter the carburetor from the gas tank, that is, plays the role of a gasoline pump. In this small but very important mechanism, fuel is mixed with air (the necessary proportion is created) and is supplied to the cylinder for combustion.

Answering the question of why to clean the carburetor of the gas outlets, we remind of the quality of the fuel that is poured into the tank. First of all, it is a gasoline mixture containing small particles of sand and other polluting substances. The filter located inside the gas tank is responsible for capturing these particles. However, smaller particles still fall into the fuel and fall into the carburetor.

These small particles gradually accumulate in the channels, reducing fuel permeability. In addition, they clog valves and cause failure of the components of the carburetor.

it is interesting! The carburetor is made of aluminum alloy, therefore, over time, the development of such a process as oxidation of metal is observed. This also negatively affects the performance of the mechanism.

Most of the owners of gas tools do not keep them properly. After all, the most important condition for the correct storage. Do not leave fuel in the tank for a long time. Why this cannot be done? Over time, the oil begins to deteriorate, and then, the next time the engine starts the engine, pure gasoline enters the internal combustion engine. The oil is located at the bottom of the tank, it flows into the carburetor and causes clogging of the channels.

TAMPERPROOF PLUG REMOVAL ECHO WEEDWACKER

it is interesting! It is important to understand that the design of the carburetor has a rubber membrane resistant to aggressive substances. However, it is impossible to allow it to dry, which can happen if all the fuel is spent in the tank, and the instrument is left in this state for a long time. The membrane will dry and stop working. With prolonged storage of gasoline bush, it is necessary to leave a little fuel in the tank.

Washing is necessary to unlock the channels and remove any pollution accumulated over many years of operation. If you follow the procedure and do it correctly, the productivity of the tool will improve. When clogging the carburetor, ICE performance is reduced, power loss, interruptions, difficulties in starting, etc.D. All this is decided by cleaning a small, but very important mechanism called a carburetor.

Signs of the need to flush the carburetor of the lawn mower

The fact that it is time to diagnose the mechanism on bench cutting will be indicated by the corresponding factors. One of the main features. interruptions in the work of the tool. In this case, the carburetor should be cleaned immediately, otherwise it is fraught with the development of negative consequences. Other symptoms of malfunctions are as follows:

  • The engine does not start.
  • Revolutions begin to hesitate.
  • The engine does not provide full power.
  • The response to press the gas button is delayed.
  • Fuel consumption increases.
  • When the engine warmed up, malfunctions occur.
  • Black smoke comes out of the muffler.

However, when the above symptoms appear, it is necessary to make sure that the reason is really a malfunction of the carburetor. Eliminate other types of breakdowns and only then start cleaning and repairing the product with a trimmer.

it is interesting! It is not recommended to disassemble the carburetor without special need, and even more so if you have no experience in this matter. The mechanism consists of small details that can be damaged or lost in case of dismantling.

In most cases, the above symptoms can be corrected by adjusting the carburetor. Detailed instructions for this process are described in this material. All devices of gasoline cutters are equipped with adjusting screws, with which idle stroke is adjusted, as well as a high and low speed range. The number and appearance of the adjusting screws depend on the model of the device.

Principle of operation

The order of injection and filtering of fuel in the engine of the lawn mower is next.

  • With the help of a throttle, the amount of air supplied to the diffuser is set. The more air is supplied, the more oxygen needs gasoline for combustion, and the greater the power released in the form of heat. The energy of the heat is further converted into a mechanical.
  • The membrane pump pumps the required amount of gasoline.
  • Next, gasoline passes through the engine fitting.
  • Fuel passes through a retractable and exhaust valve.
  • Fuel is filtered using a mesh filter.
  • Through the needle valve, it also enters the camera with the membrane.

The stages of the carburetor is as follows.

  • Air enters the pipeline with an air conditioning. The damper sets the desired air flow intensity.
  • The diffuser is narrowed in the node of gasoline’s injection. this is necessary to give a higher air flow rate.
  • Fuel passes through the bastard compartment and passes the jet, falls into this narrowing of the tube. The float compartment doses the supply of gasoline. In this compartment, the pressure is in a state of equilibrium. In a narrowed tube, it decreases. Due to the difference in both values ​​of pressure gasoline and passes through the jetler.
  • Accelerated stream sprays gasoline, converting it into aerosol pairs. The resulting gas-air mixture is ready for a rowing in the combustion chamber.
  • Having passed through the fuel pipeline, this mixture is in the cylinder of the carburetor.

Conclusion: To set the required power, first of all, you will adjust the rate of combustion of fuel using an air damper. If the gap is too small, and the oxygen in such a mixture is less than 10%. the fuel does not burn, therefore, the engine will not start or immediately staller.

In the case of buying a Chinese trimmer for grass, it is worth considering that it differs little from European- the same 2- or 4-stroke engine and drive.

However, the quality of the details is saved, forcing the consumer to change them more often. Check what compatible details offer non.Chinese companies for your device.

After removal, the naked body remains in the hands. The carburetor is disassembled.

Elimination of malfunctions and elimination of malfunctions

Now you should pay attention to the malfunctions that arise during the operation of the carburetor, and the ways to eliminate them.

Problem 1: Holes, ducts and mud nozzles are clogged

The first thing that happens. This is that holes and nozzles in the fuel system are clogged with dirt. Filters installed in the tank and directly in the carburetor do not help. They still miss small particles that lead to a fault of the bush.

Step

To do this, unscrew the bolt on the mechanism, holding it with your finger. The fact is that there spring and careless actions will lead to its loss.

We take out a needle, look at the photo and spring.

Step 9

How to remove. The most effective way is to use an ultrasound bath.

It is filled with either special liquid or gasoline, there is a carburetor and under the influence of ultrasound, the so.called cavitation effect, the channels are cleaned of pollution.

You can use the compressor installed on the farm and clean the carburetor channels. However, this method is effective if the pollution is not very large.

Step 0

Now we need to blow the channels in the carburetor housing and the lid. See the photo.

Step 11

Another piece of dirt can get stuck under a needle. See the photo. It will also lead to improper hair operation.

Important! Never use needles, pins or wires when cleaning a carburetor. Even the smallest scratches will damage the carburetor. This should be completely changed.

Task 2: Clogged filter of thin cleaning

It is located on the carburetor cover and is a small metal net. Its pollution is very common. This is due to the settlement of oil, additives and dirt on it.

Step 2

Sometimes a certain film is found when disassembling a grid. For this, the carburetor does not have enough fuel, and the motorcycle will not start or work with interruptions. Cleaning methods are identical to the first reason: ultrasonic bath, compressor or aerosol spray with a special solution. In addition, if the net is well clogged, you need to take a soft watercolor brush, immerse it in gasoline and wash it carefully without damaging.

Step 13

They have the opportunity to wear during work. After prolonged use, they are deformed, stretched, lose their elasticity, consuming fuel poorly and can no longer work normally. This also applies to the needle itself. The fact is that it is covered with a thin layer of rubber, which wears out during operation and can no longer fit tightly to the hole. Motocosis begins to work with interruptions. To prevent such damage, all worn parts must be replaced. Where to get them?

It includes two diaphragms, gasket, needle valve and spring.

All parts of the carburetor can be replaced. Therefore, you do not need to rush and buy a new one, and you also do not need to run to the workshop, repair is possible for any user of a motorcycle brush. Professionals argue that the quality of the components in the repair kit even exceeds the characteristics of the original parts of the carburetor. Thus, a well.repaired block will work better than a new.

Step 4

In addition, the manual fuel pump button may fail. The effect of gasoline on it leads to corrosion of rubber with prolonged use, and it will stick together or burst under the influence of low temperatures, for example, during storage. The button should also be replaced if necessary. In addition, its cost is small and will not affect the amount of the budget for repairs.

Based on the foregoing, we can conclude that there are only three main malfunctions of the carburetor: clogging of the channel, pollution of the thin filter and the refusal of the component. In the first two cases, cleaning is sufficient, and in the third, the repair kit will help.

If you have not found any of these problems in your carburetor, we recommend that you contact a specialized service.

How to adjust the carburetor on the trimmer of the Echo line

When gas and air flow through a carburetor, they must have an exact mixture. Otherwise, your engine on the Echo trimmer line will work poorly, slowly and may not even start at all. The adjusting screws of the carburetor install this mixture, and these screws located on the engine can vibrate eventually. Regular installation of these screws will provide the correct fuel-air mixture passing through the carburetor and engine.

Keep your carburetor properly adjusted to maximize the performance of your trimmer for Echo grass grass.

The principle of operation of the carburetor of the lawn mower

The throttle dashes determines the amount of air for supply, and the engine power directly depends on this.

Fuel is sucked into the carburetor system (its membrane). Then passes through the fitting in the carburetor. Next, the liquid moves through the intake and exhaust valve of the pump. Filtered with a net. The needle valve moves into the membrane chamber.

  • Air supply to the tube with an air septum (damper). The partition regulates the intensity of the air flow.
  • The fuel supply system is necessarily narrowed by a diffuser to increase the flow rate.
  • Gasoline through the float chamber and nozzle with narrowing. The chamber with a float regulates the temporary volume of gasoline. In the float chamber, the pressure level is neutral, and in the tube with narrowing is already low. Thanks to the pressure drop, fuel penetrates through the jetler.
  • Air flow acceleration contributes to the transfer of fuel (gasoline) and its spray. As a result, the air-fuel mixture of the necessary proportion or density is formed.
  • The air-fuel mixture penetrates the engine cylinder through the fuel tube.

The level of air density in the system depends on the area of ​​the open air damper. The wider the damper is, the greater the fuel consumption and power.

Simply put, adjusting the carburetor on a benzocos. creating an optimal fuel mixture due to the correct air supply.

The main problems and malfunctions of the carburetor.

Mesh filter. There are only two tasks with this element more often:

In order to find out the cause of the breakdown, the fuel filter lid is unscrewed to extract the mesh filter. If the mud just accumulated on it, then flushing in gasoline or purge will help.

With visible damage on the mesh filter, it is necessary to put a new. There may also be damage to the fuel supply pipe (during the repair they practice checking this element).

The starting device of the carburetor almost always does not work due to blockages. Should be used for flushing acetone or the same gasoline.

Purging parts of a carburetor with click of compressed air. permissible and comfortable repair practice.

The hull of throttles, places of ligaments of the parts of the carburetor, intake or graduation pipeline. all of the listed parts are subject to depressurization. You can probably check the simple method. spread the problem area with soap foam.

Washing with partial disassembly

The process of washing the carburetor with its partial disassembly is considered using the Solex carburetor and the Jet 100 Ultra carburetor. You don’t need to buy a lot. One can be enough with a volume of 200 ml. In addition to special fluid, you will also be required:

  • set of wrenches;
  • Cross and slotted screwdrivers;
  • Passatigi;
  • a capacity with a wide “throat” with a volume of 2-3 liters (for soaking the carburetor cover);
  • a capacity with a wide “throat” with a volume of 0.2–0.5 l (for soaking small parts);
  • kerosene (purified gasoline, acetone);
  • tire pump or compressor with a tapering tip;
  • toothpicks;
  • Old toothbrush;
  • pure dry fabric that does not leave the pile (better rough);
  • Small wooden blade (like ice cream sticks).

  • We go to the nearest gas station.
  • Unscrew the fuel tank plug.
  • Open a jar with flushing liquid (opens like a beer bank).
  • Using a watering can, pour the product into the tank.
  • Pour gasoline into the tank (until complete);
  • We drive by car until the fuel is over.

According to the manufacturer, the Hi-Gear HG 3205 additive helps not only self-cleaning of the fuel system, but also helps:

Maybe, of course, everything is not so colorful, but having drove 300-400 km on this additive, you will notice positive changes in the engine operation. To maintain the fuel system and carburetor in particular, it is recommended to repeat the described procedure every 3000 km of run.

You can adjust the carburetor of the lawn mower with your own hands

lawn mowers, like the entire bench tool for the garden, is not difficult to maintain equipment. Repair, set up on your own and it is necessary. For example, adjusting the carburetor of the lawn mower with your own hands is the matter of five minutes.

Карбюратор от газонокосилки — это узел в системе питания. В нем, как и любых карбюраторах, идет процесс смешивания воздуха и топлива (бензина) для дальнейшей подачи в двигательные цилиндры.

В данном процессе главное – верная пропорция горючего и воздуха, для чего и регулируют карбюратор.

Сетчатый фильтр. С этим элементом чаше всего две проблемы:

Для того, что выяснить причину поломки откручивается крышка топливного фильтра для извлечения сетчатого фильтра. Если на нем просто скопилась грязь, то поможет промывка в бензине или продувка.

При видимых повреждениях на сетчатом фильтре нужно обязательно ставить новый. Также могут быть повреждения на патрубке подвода топлива (при ремонте практикуют проверку этого элемента).

removing, carburetor, trimmer, echo, grass

Пусковое устройство карбюратора в большинстве случаев не функционирует из-за засоров. Следует использовать для промывки ацетон или тот же бензин.

Продувка частей карбюратора с засором сжатым воздухом – допустимая и удобная практика ремонта.

Корпус дроссельных заслонок, места связок деталей карбюратора, впускной или выпускной трубопровод – все перечисленные части подвержены разгерметизации. Проверить наверняка можно примитивным способом – проблемный участок намазать мыльной пеной.

Основа карбюратора газонокосилки – алюминиевый корпус. В нем расположен диффузор (отверстие с внутренними контурами). Через это отверстие нагнетается воздух. От сечения (проходного отверстия) диффузора зависит скорость подачи кислорода (воздуха).

Диффузор оснащен топливными каналами. Из них втягивается топливо при помощи потока воздуха.

У карбюраторов бензоинструмента есть малоизвестная,но серьёзная проблема,которая легко лечится.

Запчасти для китайских мотокос Китайская газонокосилка ремонт …

Дроссельная заслонка определяет количество воздуха для подачи, а от этого напрямую зависит мощность двигателя.

В карбюраторную систему засасывается топливо насосом (его мембраной). Затем проходит через штуцер в карбюраторе. Далее жидкость движется через впускной и выпускной клапаны насоса. Отфильтровывается сеточной. По игольчатому клапану движется в мембранную камеру.

  • Подача воздуха в трубку с воздушной перегородкой (заслонкой). Перегородка регулирует интенсивность воздушного потока.
  • Система подачи топлива обязательно заужена диффузором для увеличения скорости потока.
  • Бензин через поплавочную камеру и жиклер трубку с сужением. Камера с поплавком регулирует временный объем бензина. В поплавочной камере уровень давления нейтральный, а в трубке с сужением уже низкий. Благодаря перепаду давления, топливо проникает через жиклер.
  • Ускорение воздушного потока способствует переносу топлива (бензина) и его распылению. В итоге образуется воздушно-топливная смесь необходимой пропорции или плотности.
  • Воздушно-топливная смесь проникает в цилиндр двигателя через топливную трубку.

От площади открытой воздушной заслонки зависит уровень плотности воздуха в системе. Чем шире открыта заслонка, тем больше расход топлива и мощность.

Проще говоря, регулировка карбюратора на бензокосе – создание оптимальной топливной смеси за счет корректной подачи воздуха.

Перед регулировкой необходимо тщательно прочистить фильтры согласно техническому обслуживанию в инструкции.

Дальнейшая настройка карбюратора газонокосилки своими руками выполняется регулировочными винтами. Всего их три:

Правый (L) – регулировка топливной смеси для низких оборотов.

Нужно найти максимальные обороты на холостом ходу. Для этого неспешно выворачивают винт (L) вправо и влево.

Для регулировки поворачивают винт на четверть оборота обязательно против часовой стрелки.

Нижний (T) – отвечает за регулировку двигателя на холостом ходу.

Для правильной регулировки именно холостого хода характерно:

  • устойчивая работа холодного двигателя;
  • не завышенные обороты горячего двигателя;
  • для триммерной головки большой запас оборотов;
  • устойчивая работа двигателя при смене положения (резкое подъем или спуск ножа).

Извините за банальность, но карбюратор мотокосы — это не космический корабль внеземной цивилизации, и его ремонт вполне возможно произвести своими руками. Для уверенности в своих действиях ознакомьтесь с пошаговой инструкцией, представленной в этой статье.

Визуальный осмотр карбюратора поможет выявить подтекание топлива ипосос воздуха, но главные причины отказа устройства кроются внутри. Поэтому чтобы определить и главное исправить поломку карбюратор нужно разобрать.

Чтобы разобрать карбюратор мотокосы много усилий не нужно.

Достаточно отвинтить четыре винта с одной стороны

и два с другой. Сделать это можно при помощи обычной крестовой отвёртки. Аккуратно откручиваем винты и складываем в сторону. Они могут понадобиться при сборке. Желательно перед разборкой стол застелить белой тканью, чтобы было видно все, даже самые маленькие детали, которые могут выпасть при разборке.

Разборку начинаем со стороны системы подачи топлива.

Снимаем праймер – пузырёк подкачки, что примечательно, при сборке установить детали карбюратора неправильно просто невозможно. Изделия имеют характерные отливы и отверстия.

Теперь снимаем мембрану. Именно она выполняет функцию перекачки топлива в карбюратор.

При вибрации мембрана другой стороной оказывает давление коромысло механизма и поднимается игла, которая, в свою очередь, открывает отверстие и происходит подача топлива.

Снимаем крышку карбюратора с механизмом впрыска.

Далее, установлена еще одна мембрана. Её аккуратно снимаем.

Под мембраной находится еще одна прокладка. Её тоже бережно убираем, ни в коем случае не повредив.

Дальше переходим к демонтажу деталей с обратной стороны карбюратора. Как и, говорилось ранее, откручиваем два болта. Это уже система подачи воздуха.

Здесь расположена задвижка, которая при прибавлении «газа» открывается и увеличивает приток воздуха в двигатель.

После ее снятия в руках остаётся голый корпус. Карбюратор разобран.

Определение неисправностей и их устранение

Теперь стоит обратить внимание на неполадки, которые случаются при работе карбюратора и способы их устранения.

Первое, что случается, это забиваются грязью отверстия и жиклеры в системе подачи топлива. Не помогают фильтры, установленные в баке и непосредственно в карбюраторе. Они все же пропускают небольшие частицы, которые и становятся причиной отказа мотокосы.

Для этого откручиваем болтик на механизме, придерживая его пальцем. Дело в том, там есть пружина и неосторожное действие приведет к тому, что она потеряется.

Чем выполнить продувку. Самый действенный способ – это применение ультразвуковой ванны.

Она наполняется либо специальной жидкостью, либо бензином, туда помещается карбюратор и под действием ультразвука, так называемого эффекта кавитации, каналы прочищаются от загрязнений.
