Pour a carburetor on a trimmer for Patriot grass. Diagnosis of the filters of the lawn mower

Patriot trimmer does not start. Floods the candle on the gas troops what to do

If on a wet candle it is still possible at least some appearance on the electrodes of the spark discharge, then on a “flooded” candle of spark discharge will be already impossible. We hear about “flooded” candles more often than about “flooded” engines. It is even difficult for many to imagine such an engine until they are faced with this personally.

Wet sparking candle or flooded candle is the main feature of either a non.working candle, the absence of high voltage voltage on the electrodes of the candle, or re.enrichment of the fuel mixture supplied to the engine operating chamber.

In addition, this can be attributed to cases with poor.quality fuel, a reduced high.voltage stress and a weak compression degree. As a rule, one thing entails some other manifestations and you can easily get confused in determining the main, main reason for the malfunction.

Spark plug. Another lawn mower fell into our hands, or a benzotrimer, where they could not run the engine. No recommendations from observers and “friendly” neighbors did not even help. Replaced the spark plugs with new ones, but there was no result, and each next candle was twisted with wet.

Air filter of the engine of the lawn mower. The engine of the benzotrimmer was opened in stages. The air filter ring was moistened with the fuel completely. In the compartment where the filter element is installed, there was a large amount of fuel.

The throughput of a wet filter decreased, and even with a dry light of the ignition, the engine could not start due to the overlap with a wet filter element of supply of the required amount of air. Electrodes of the spark plug immediately, when the engine was first attempted, filled with fuel.

The muffler of the lawn mower. Through the fasteners of the muffler, on one of the fasteners, it was clearly visible an oil stain. Traces of oil can appear with a weak tightening of fasteners, when the pairs of waste oil along with exhaust gases seep through weak seals, but on this benzo.tank, the tightening of the nuts corresponded to the required effort.

Chinese lawn mower will not start. The candle is wet.

And in the muffler itself we found about 50 60 ml of fuel. Not oil, but the very fuel that was in the fuel tank.

Chinese lawn mower will not start. The candle is wet.

The engine of the lawn mower. When opening the engine, we expected to find some kind of surprise, and this was not a vain expectation. A certain amount of dense soot soot was present on the piston. The layered piston rings and a piston layer on the piston pointed out that when working with a benzocosa, the temperature regime of the engine was exceeded, which worked on a reinforced mixture.

Many manufacturers write directly at the container that the oil has good anti.dysfunctional, lubricating, anti.corrosion and temperature properties. But none of them will write: “Do not overheat the engine!”Or” strictly adhere to our recommendations!»What was poured instead of oil, or poured oil unmarried, it is difficult to say.

Crankcase. Most of all we were surprised by the engine Carter, which turned out to be filled with fuel full to edges. It happens when a certain amount of fuel is assembled in the engine crankcase, but that the crankcase is completely flooded with fuel. this is a rarity for us.

The engine worked ‘in the sweat of the face’, and the operator did not pay attention to fuel consumption, increased smoky, and lowering engine speeds. The engine of the lawn mower flooded at the very edges of the crankcase.

The carburetor of the lawn mower. There were no difficulties when disassembling a carburetor. Outside, the lawn mower carburetor was wet and dirty, which indicated fuel leakage, but we did not find the place of leakage at the external inspection itself.

And inside the carburetor there were dense deposits located along the edge of the hole of the saddle of one of the valves of the membrane, which spoke about the poor operation of this valve, when its petal was not pressed tightly to the saddle.

Gasoline does not start hot. Pull the gas mechanism and pull the cord abruptly several times until the engine starts to work, then click on the trigger. Do not start. Specialized repairs are required.

Checking the ignition system, if the gasoline pump is not launched, is performed in series:

pour, carburetor, trimmer, patriot, grass, diagnosis
  • remove a candle from carbon and dirt, dry, install a gap of 1 mm;
  • Connect to a high.voltage wire and check the spark, pulling several times behind the starter;
  • In the absence of a spark, check the integrity of the high.voltage wire;
  • Replace the candle;
  • dry the candle channel;
  • At the same time, the operation of the ignition coil is checked. it is faulty if the working candle does not sparkle.

In case of malfunction, the ignition coil of the gasoline pump

does not start hot, kiosks, works with breaks.

Cleaning or replacing air and fuel filters will provide the necessary consumption of ingredients entering the carburetor. Air filter can be washed in soapy water or replaced. If nylon tissue is used, it is washed, the porous felt filler is replaced. The fuel filter changes neatly, leaving the absorption of the nozzle open. Is the air filter replacement is necessary, whether it is possible to start the engine with a remote air cleaner. Do I need to change the net on the fuel supply. if gasoline pump

Breath, a hole for supplying air to the gas tank. If it clogs, a vacuum is created in the tank, and the mixture is not included in the carburetor. The hole can be blown with air or cleaned with a needle. The exhaust channel must be cleaned, it is necessary to remove the wiping mesh of the muffler.

The maximum and minimum engine speed is regulated by a carburetor. The stable operation of the fuel pump depends on the amount of the fuel mixture and the supplied air, as well as on their ratio. Gasoline does not start if the carburetor is incorrectly configured. The procedure for installing a device for supplying fuel at low speed (l), high speed (n) and (t) is regulated by the same screws:

  • The chainsaw should work for at least 10 minutes, since the adjustment is carried out hot.
  • Plunge the screw H smoothly at maximum speed, then turn 1/4 counterclockwise, reduce the speed of rotation of the engine shaft.
  • The idle stroke is regulated by the screw t, guaranteeing that the braid for the grass does not rotate.
  • The screw l is regulated, first opening the maximum throttle, and then gradually reducing the speed to a stable minimum.

After adjustment, a good carburetor with peeled filters, the proven ignition should ensure the operation of the engine. In the event of a carburetor malfunction after repair, the supply system must be adjusted again before launching a gasoline pump

Rare breakdowns that prevent the operation of gasoline pumps can be:

The most common malfunction, the elimination of which is associated with the replacement of the engine, may be the refusal of the group of piston engines. The cost of repair will cost about 70% of the cost of the product. To understand the reasons why the gasoline pump does not start, the video will help:

Operating and repair instructions

Correctly choose a gas trimmer for grass. This is a simple task for those who use the device for the first or after winter downtime. Before starting the unit and using the starter, you must fill in the brush with oil. This substance should contain certain additives that easily dissolve in fuel when exposed to high temperatures. Such substances will provide proper protection of the engine elements, protecting against friction even with a large load.

It is not difficult to work a trimmer with a warm engine. To do this, set the switch to the working position, and then tighten the cord before starting. If you follow the instructions, there should not be problems with the launch.

The most common launch errors:

Depending on the work performed, a trimmer for the grass is installed on the trimmer for the grass. Starting a braid for grass means using an engine at a minimum speed without load. For a breakthrough, you must start a brush and use it in standby mode. This step is best performed by inserting the wire, gradually increasing the load level and increasing the engine rotation frequency. After the refusal, the first operation of the device should take about 15 minutes.

Trammers for grass for Patriotes, like any other similar method, should be used with caution, avoiding sudden movements, as well as clashes with extremely hard objects. Let the brushes cool after each use. Also, the user should not forget to put on the belt before using the technique: this element will help optimize the return, as well as distribute the tension throughout the body. The belt should not only be worn, but also fitted under you.

The fact that it is correctly fixed is evidenced by the lack of rapid fatigue of the hands, as well as unpleasant sensations in the muscles.

It should be remembered that the use of a gas trimmer for grass is extremely undesirable in raw and rainy weather. If the device is wet, it should be sent to a dry room, and then dry it. Continuous work of the Patriot bureau can take from 40 minutes to an hour. When working with this device, follow the following precautions:

How to configure a trimmer for Patriot grass

Lawn mowers have long entered our lives as a very useful tool and an excellent alternative to an ordinary spit. The lawn mower and the lawn mower is the same tool. And trimmers for grass are gasoline, and there are electric. In this case, we will talk about gasoline. This unit is quite easy to operate, but has its own characteristics. The lawn mowers are equipped with an internal combustion engine. Carburetor Motokosa is a very important component of the tool. The main task of the carburetor is to ensure the intake of the fuel engine enriched with air into the cylinder. Here the most important thing to observe the balance of fuel and air. The article will talk about the signs indicating the need for adjustment on how to configure the carborer on the trimmer.

It is allowed to adjust the carburetor trimmer for the grass on its own, having previously studied the device of the unit. As a rule, a detailed description of the components of the tool components is in the instruction manual. An experienced master is even able to determine that there are shortcomings in the work of motorcycles. The sound of the motor with proper tuning should be perfectly even. If screaming sounds are clearly audible, then the mixture is oversaturated.

Causes of carburetor breakdowns

When operating, motorcycles (for example, “Patriot” or “Union”) can be damaged, and the user will need to repair it on its own or with the involvement of specialists. This can happen for a number of reasons. One of the most common is non.compliance with the rules for using the device. If, with prolonged operation of the trimmer for the grass, the carburetor was not used and adjusted, the device breaks.

Another cause of the breakdown is an incorrectly prepared fuel mixture. Often the owners of the equipment buy oil and prepare fuel according to the recommendations written on the package of combustible materials, which is incorrect. When preparing fuel, you need to consider the instructions for the operation of the Motokos itself. In addition, the mixture “by eye” should not be made, since incorrect proportions also lead to breakdown of technology.

Most of the breakdowns of carburetors are equally characteristic of motorcycles of different brands, whether Echo, “cedar”, Homelite or the device of another manufacturer.

Chips on the choice

In accordance with the current statistics, it is the gasoline models of mowers that are most in demand. This is largely due to their mobility and functionality. However, when choosing a specific model of technology, it is necessary to take into account a number of other parameters. In such situations, it will be useful to compare motorcycles with other types of trimmers.

Electric devices are connected to a household network with a voltage of 220 V. Such machines do not pollute the air due to the lack of exhaust gases. No less important points will be the minimum noise level and relatively small weight. At the same time, the processed area is significantly limited.

The battery models today are the least common trimmers for grass for grass. The electric engine of such mowers does not feed from the network, but from the battery, which provides maximum mobility. However, the operating time of the equipment is limited by the battery charge and is an average of 35-45 minutes. Another important point is the relatively high cost of battery models.

When choosing a specific model of a gasoline trimmer for grass, it is necessary to take into account its technical characteristics. So, low.power devices are equipped with coils with a fishing line. On more reserved and powerful models, knives and cutters can be used as cutting elements

On more reserved and powerful models, knives and cutters can be used as cutting elements.

The performance of the spark plugs

If there is a need to figure out why a trimmer for grass is not started, then the state of contacts of the installed candle should be checked. In this case, you can figure out why the lawn mowing engine does not occur. For high.quality diagnosis of the spark plug, you must definitely adhere to the following scheme:

  • If during the dismantling it was found that the candle was wet, then in a small combustion chamber there is a certain part of the fuel, from which you do not need to rush to get rid of. To eliminate the problem, it is necessary to dry and carefully clean the contacts. After the manipulations done, you should carefully connect the candle. You need to turn on the ignition and without unnecessary efforts pull the starter handle. If the device is regular, then there will be a constant and bright spark. Otherwise, you have to replace the candle.
  • The state of involved electrodes can be considered ideal when they have a characteristic dark brown fog. If the candle has a white or even black soot, as well as wet, then it must be immediately replaced.
  • A trimmer for grass may not respond to launch due to the fact that there is too much gap between the contacts of the candle. To set the optimal gap, you need to use special multibody probes.

If, after all the manipulations done, the engine of the lawn mower did not start, then the cause of the malfunction must be sought in a carburetor or heat supply. Otherwise, you will have to check the serviceability of the involved high.voltage wire.

Electric trimmer for grass vibrates

Many mowing users noticed that some time after the start of the apparatus, it begins to vibrate very much. On some trimmers, mainly in models more expensive, an anti.vibration system was installed in the form of shock absorbers seized between the engine and the bar. But in some cases, even she does not save from strong vibration. The reason that strong vibration appears in the trimmer, there may be a small amount or complete absence of lubrication on a hard or flexible shaft located inside the rod of the apparatus.

  • unscrew the gearbox located at the bottom of the bar;
  • After removing the gearbox, you will see the end of the shaft, for which you need to pull to extract the part;
  • after extracting the shaft, it must be abundantly lubricated with a special lubricant “Shrus-4” or ordinary-“Litol-24”;
pour, carburetor, trimmer, patriot, grass, diagnosis

Clicking Carburetor Noise On My Lawn Tractor. What Is It? Teaching Apprentice Dave

  • Apply a small amount of lubrication to the shaft and evenly smear it along the entire length of the part, including the slots at the ends of the rod (if they worked, the shaft will have to be replaced);
  • After lubrication, insert the shaft back into the bar and put the gearbox in the same place.
  • unscrew and remove the mowing head;
  • remove the bar from the electric motor by unscrewing a couple of bolts;
  • Pull out a flexible cable from the bar;
  • Lubricate the cable with grease along the entire length.

This is done like this: first you need to lubricate the end of the cable, and then insert it into the bar, after which, as it moves into the pipe, you should apply grease to the part and evenly distribute it on the surface. Then insert a bar with a flexible shaft into an electric engine and fix it.

In the event that the lubricant did not help, and the vibration continues to appear, you will need to change the flexible shaft.

Checking the fuel mixture

Suppose you don’t start a trimmer for grass. In this case, the first thing is to check whether the fuel is enough in the tank, as well as evaluate the quality of the fuel mixture. To refuel a motorized unit, it is necessary exclusively high.quality gasoline. It is recommended to use fuel, the brand of which is not lower than AI-95. Refueling a trimmer for grass with fuel of unknown origin, not bought at a gas station, is fraught with frequent failures in the work of the tool. This can cause a breakdown of the cylinder-piston system. Repair in this case often exceeds the cost of the device itself.

Why is a trimmer not starting for grass gasoline? Incorrect preparation of the fuel mixture may also lead to this, which consists of oil and gasoline. The proportions in which the specified components are connected are indicated by manufacturers in the guide for the operation of a trimmer for grass. Preparing the fuel mixture is extremely not recommended in large volumes, that is, for the future. Indeed, with prolonged savings, there is a loss of the determining properties of the substance. Therefore, if a trimmer for grass does not start, it is worth draining the old fuel and use freshly prepared fuel mixture.

The trimmer for the grass is very hot

Overheating of a trimmer for grass can occur for many reasons:

  • Gasoline has not the same octane number indicated in the instructions for the unit;
  • the proportions of gasoline and oil during the preparation of the fuel mixture are not observed;
  • A mixture of fuel with butter has long been prepared (the mixture cannot be stored for more than 2 weeks);
  • The trimmer for the grass works more than the time instructions;
  • A low.power trimmer for grass on thick and hard grass is used, the device works with overload and quickly heats up;
  • shifted towards the bar or the cassette lid clutched.

The latter happens if you install the mowing head inappropriate for this unit

, or when the axis shifts inside the bar. These changes make it difficult to rotate, the load on the engine increases, and it overheating.

Diagnosis of the candle channel

What to do if the used fuel mixture is in perfect order, but a trimmer for grass is still not started by gasoline? The reasons for the refusal of the mechanism may lie in excessive moisture of the candle channel. To diagnose and eliminate the problem, it is necessary to do the following:

  • To twist the candle. Wipe it thoroughly, and then dry it.
  • Drain excess fuel in the chamber through the corresponding candle hole.
  • Clear the old candle if there is a dozen on its surface. Cope with the task will allow the use of a conventional ladies’ nail file or file.
  • When installing the element in place, set a gap of 1 mm. What are the causes of the breakdowns of the cavity device of the chainsaw, why the chainsaw is not started and how the malfunction will eliminate. Why doesn’t start for which the trimmer does not start for grass and you have a gas station. To check the parameter, it is enough to place any coin in the lumen.
  • Collect a functional block back.
  • Try to start a trimmer for grass.

It is recommended to perform a candle channel to dry for at least half an hour. However, in no case should you resort to the calcination of its elements. After all, heating the spark plug can lead to its final corruption. Что предпринять, если обслуживание функционального блока было выполнено в соответствии вышеуказанным рекомендациям, но триммер для травы не заводится, искра есть при этом? In this case, it should be treated with gasoline threaded connection. The latter does not need to be saturated abundantly fuel. It should only be slightly moisturized. Resort to such actions should be to ensure the ignition. The gasoline trimmer for the grass does not start? Reasons and decisions on. After all, no matter how much the candle gives a strong spark, in an absolutely dry chamber there simply will not be something to ignite.

Why the lawn mower is not started? Diagnosis of trimmer faults for grass

In this video, we will try to consider the main malfunctions that occur during the operation of the motorcycle.

Practical tips for eliminating faults. From personal experience.

If even in this case a trimmer for grass does not start, it is worth evaluating the quality of the contact between the high.voltage wire and the candle. In the absence of a spark (in the presence of a reliable connection between the indicated elements), most likely, the problem is caused by breakdown of the ignition unit. In this situation, you will have to turn to the services of masters who will reinstall the knot.

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.

How to Fix a Trimmer Carburetor

Carbon regulation

Wash the air filter before adjusting the carburetor. It is recommended to rinse every 10 hours. After that you can start tuning. On the example of the photo shows a carburetor of a gasoline trimmer for PRorab-8406 grass. The numbers indicate the adjusting screws that we will use.

Rifles for adjusting the carburetor carburetor Prorab-8406

Run the brush and wait until it warms up.

Fuel adjustment

Start slowly tighten the propeller, which regulates the fuel mixture until the engine stops or freezes if you have not caught the moment. Then unscrew the screw for a quarter of turning if the engine does not work, or by half a turn, if it does not work. Run the stopped engine. Check, opening the throttle, as the engine accelerates. Continue to unscrew the screw for a quarter of turn, until the engine begins to confidently gain increased speed when supplying gas. This will be the moment of the most economical stable engine operation. On the gas trimmer, the Prorab-8406 adjusting screws are rotated clockwise, unscrewed. Counterclockwise, some other brands can be the other way around.

Cooper adjustment

We proceed to setting low speed. The screw limits the reverse movement of the throttle lever. Turning it, we increase the olfactory speed, unscrew it, reduce it. Adjust so that the engine works confidently at low speeds and even a little faster (for better launch), but so that the reel of the fishing line or the knife does not rotate, and before you start to rotate, there is a sufficient supply of speed. If the engine does not start well, still increase the idle speed.

Limiting maximum speed

After adjusting the consumption of the fuel mixture and low speed, check how the bush cutter engine works at maximum speed. If necessary, limit the maximum speed to the desired level using a hollow screw, unscrew the lockshop and tighten it to reduce the maximum speed, or unscrew it to increase it. After adjustment, tighten the nut. Installation of maximum speed is necessary to protect the trimmer motor for grass from overheating and the possibility of using keys blocking to reduce the fatigue of the right hand.

You may have to adjust the trimmer for the grass of the carburetor later. For example, if the engine begins to gain poorly when working at full load, unscrew the screw by another quarter turnover. If the launch is difficult, increase the blast speed. Weather conditions and the quality of the fuel mixture can affect the work of black cutters. Vibrating screws themselves can also overturn from vibration.


There are not only situations when trimmers for grass do not start, but cases when after launch they work for a couple of seconds and immediately stall. Inspect the light of the ignition again: if it is “thrown”, and this situation is repeated even after wiping it and drying, proceed to the “audit” of the air filter.

Most likely, he is completely erased and needs to be replaced. If everything is fine with the filter, it may be so that the ignition coil has failed.

In the case when the trimmers for grass do not start, and you have done all of the above, a muffler may be clogged. It needs to be dismantled, burned on a burner, after which the entire carpet can be easily shaken out.

And again the carburetor.

Well, even if after such bullying your trimmer does not start for the grass, you can’t do without disassembling the carburetor. It may very well be that everything is to blame for the gathering of the needle in it. In any case, the disassembly and washing of this capricious mechanism certainly will not hurt.

In general, when a trimmer for the grass began to be capricious and stall, it is advisable to carry out complete prevention: to completely change the fuel mixture, try another oil, and also mandatory change the candle. Practice shows that in many cases, it is precisely cheap low.quality candles that are to blame.

We examined the most typical reasons why a trimmer is not started for grass. If the matter is something more “exotic”, do not pass the campaign in the service center. You will probably find smaller and obvious breakdowns yourself.
