Clapping from a muffler of a lawn mower
Why is the lawn mower smoking? Is it dangerous? What are the reasons for this phenomenon? Let’s figure it out. Smoke is an alarming signal. In this article we will find out what can cause this problem. And also lead you through the recovery process for each of the reasons.
Problem 1: carburetor (black smoke)
The carburetor mixes the air and fuel in an ideal ratio for combustion. If the carburetor does not work properly, this ratio may be wrong.
Too little fuel will damage your engine, too much fuel will create a too rich mixture. Excessive fuel will not fully burn out, which will lead to the accumulation of carbon, which leads to the appearance of black smoke.
You can remove the carburetor, disassemble it, carefully clean and check for damage. If necessary, it should be replaced. Be careful not to damage nozzles during cleaning.
For most manufacturers of engines, the ratio of fuel and air in the carburetor is ideal for engines operating at sea level. If you live at a greater altitude or mountainous area, more rarefied air can affect the ratio, and you can install a high.altitude set.
Problem 2: Air filter (black smoke)
Air filter prevents garbage, such as dirt, dust and grass, in a carburetor and engine. If you do not clean the air filter for too long, it will ultimately block and stop supplying air to the engine. As we know on the example of a carburetor, a lack of air means too much fuel, which again leads to the appearance of black smoke.
You must check the condition of the air filter at least once a month. The filter should be replaced at least once a year. It is important to use the filter specifically for your lawn mowing model. The wrong size will not filter the garbage properly.
Problem 3: piston rings (white smoke)
Piston rings form a seal between the piston and the walls of the cylinder. If they wear out or damage, the oil can leak through the rings into the combustion chamber, which will lead to the release of white smoke.
To avoid this, make sure that the air and fuel filters are clean. If they are dirty or completely absent, there will be dirt in the combustion chamber, which will lead to wear of the piston rings and walls of the cylinder.
Do not neglect oil in a lawn mower. Poor oil or low amount of oil cannot be lubricated correctly, which leads to wear of piston rings and cylinders.
Check the oil more often to prevent wear or jamming of the engine. Oil should be changed after about 50 hours of use. Old, dirty oil contains particles that air or fuel filters cannot capture, and further use of this oil will lead to engine wear.
Replacing damaged piston rings and cylinders. a difficult repair, since to access them the engine must be disassembled. Regular maintenance is much easier than full repairs!
Another important point (white smoke)
It happens that when turning the lawn mower to the side to clean the deck, the engine from the engine in a small amount can fall into the muffler. In the future, when working, for some time it will smoke white until it burns out oil from the muffler. There is nothing wrong with this, but you must definitely pay attention to the level of oil before starting the lawn mower.

Moorer for a walk.behind tractor: manufacturing, shoots, flame, video
The excellent operational properties of motoblocks have long been appreciated by satisfied landowners, only some of the components of the unit elements often cause a walk.behind tract. In an attempt to deal with the problem that has arisen, experts find “weakness” in the form of poor.quality and not withstanding the load of the muffler.
Launching the lawn mower
Before you start a gas mowing gasoline, a visual inspection should be carried out for visible damage. The process of starting the unit is conditionally divided into several stages.
Preparation of the fuel mixture, refueling
If the launch of the lawn mower is carried out after the winter, the contents of the tank are checked: in the presence of unused fuel, it should be drained. Then you can start refueling equipment. It is important to know some nuances here here.
For refueling two.stroke engines, it is necessary to use the fuel mixture. It can be purchased in the finished form or prepared yourself. There is nothing complicated in the preparation of the mixture, but you need to adhere to the necessary proportions.
When using synthetic oils, a proportion of 1:50 is used. 5 l of gasoline 100 g. oils.
When using mineral oils, the proportion is 1:35. 100 g. Oils at 3.5 l of gasoline.
Four.stroke engine refueling does not require preparation of the fuel mixture. A special crankcase for oil is provided here, gasoline is poured separately. It is important to remember that the oil also requires replacement, depending on the intensity of using the lawn mower. It is mainly necessary to change the oil every 50 motorcycles or at least once a year.
Important! Lawn mowers work well when using oil with viscosity index SAE-30. In addition, if the engine is carried out in synthetic oil, in the future it is impossible to replace it with mineral and vice versa and vice versa.
As for gasoline, the lawn mowers of Chinese, Japanese and American production work well on the fuel of the A-92 brand, it is better to use gasoline with a large octane number for European models.
When refueling the mower, you need to ensure that the level of gasoline is 2-3 cm below the edge of the fuel tank.
Launch of an unheated engine
Before you start an unheated lawn mower, a transmission, ignition system, and a motor shaft with a starter or starting cord is scrolled.
Further a number of actions are performed:
- The ignition is turned on;
- The air damper closes;
- The engine is launched.
Gasoline gasoline Stiga Collector
If the lawn mower does not start, you will have to carry out a number of manipulations:
- The damper remains closed, the ignition is on;
- The fuel pump button (suction) is pressed about 5 times;
- An attempt is made to start a motor.
In the case of repeated failure, it follows:
- open the damper to prevent suppositories for filing candles;
- scroll the shaft with the starter;
- blow the combustion chamber;
- start the engine.
Sometimes for the first launch of the motor it may take about 15 jerks. this is quite normal for this technique.
When the engine starts, the gas lever is squeezed out once to use idle. Then the lever is set to a position corresponding to low speeds. In this position, the engine should work for about 5 minutes to warm up. If necessary, its work can be stopped by pressing the “Stop” button.
Attention! It is not recommended to work with an unfinished engine. this affects its performance and durability.
Launch of a heated engine
The launch of a pre.warmed motor is much simpler and no longer requires such efforts:
Errors at start
The most common errors when starting a gasoline lawn mower are:
- Insufficient or complete absence of gasoline. A banal but fairly common reason why the lawn mower does not start. The tank is checked, gasoline is added to the desired volume.
- Low.quality fuel or incorrectly prepared fuel mixture. In this case, it is very important to study the recommendations and instructions on the issue of the required fuel quality, regarding the using the lawn mowing model.
- Incorrect position of the air damper. If the damper is closed, and the number of jerks is more than 5, there is a risk that the fuel will flood the candle.
- Turned off the ignition during launch. The ignition should be turned on immediately after the air damper closes.

The main breakdown of the lawn mower
Despite the large selection of manufacturers and the variety of models, the reasons why the Makita, Honda, Husqvarna law mower is not started, they are the same for everyone.
The main reasons why the gasoline lawn mower will not start or start, but immediately stalls, there may be problems with ignition, carburetor, filters.
If the flooded combustible and fuel mixture is high.quality and in the right amount, the air damper is closed, the lawn mower starts and immediately stalls the reason may lie in the following problems:
- Faulty or flooded light of the ignition. In this case, you should twist the candle, dry it well and cleaned thoroughly with a file or a file. Excess fuel drains, the candle hole is dried. A gap of 1 mm is set, and the candle is again screwed.
Important! It takes at least half an hour to dry the channel.
- Dry threaded connection. It should be greased with gasoline so that the spark can flare up.
- Lack of sparks from a candle. In this situation, the contact of the candle and the high.voltage wire is first checked. If the contact is normal, and the lawn mower issues cotton and stalls, the ignition is a problem, and without a service center you can not do.
Damage these are frequent reasons why the Husqvarna lawn mower is not started.
Frequent reasons for the breakdown of garden equipment, including why the Honda lawn mower is not started, are problems with an air and fuel filter:
- Clotted air filter. If the first possible causes have not been confirmed, and the lawn mower still stalls, you can extract an air filter and try to start the device without it. If the stalled engine starts, the reason is in it. The filter should be cleaned or replaced with a new.
- Polluted fuel filter. Another possible diagnostic option. The filter element is examined and, if necessary, replaced.
Important! Working a lawn mower without a filter element is extremely not recommended.
The following breakdowns are more serious and without certain skills it will not be easy to cope with them. There are problems in the malfunctions of the carburetor:
- Placers of nozzles and channels. They are washed with special liquids, blown with a stream of air from the carburetor.
- Wondered gasket. Its replacement for a new gasket is carried out.
- Damage to tightness. Diagnosis is carried out using a tonometer. If the pressure is stable, everything is fine, it falls. you need to find and replace the damaged element.
Another breakdown option is the disguise of the piston group. Worn or damaged pistons should be replaced.

Restoring the performance of electrical equipment
Mowers, inside of which electric motors are located, most often begin to be capricious due to oxidation of contacts. The terminals are covered with a layer of scale from excess humidity in the room or in another place of storage. It is also worth checking the absence of a break in wires in problem areas. For this operation, a multimeter or other tester type is used.
When a set of garden equipment contains a brush engine, we identify the performance. Brushes can wear out quickly, leading to a lack of contact. The reptity of them costs relatively little, and it is easy to find it in specialized stores, where they sell spare parts for such a technique.
Asynchronous engines are also in wait for the malfunctions. They refuse phase.drive capacitors. A similar situation is diagnosed at home is problematic. It can be detected by indirect symptoms:
- The sound of a buzz is heard;
- When starting, the case twitches slightly;
- significant heating of the motor occurs even at a slight load;
- Reduces are reduced.
It is worth diagnosing the condition on the tolerance/button and the voltage supply to the electric motor.

Then you will have to use the services of the corporate service.
Why the lawn mower is not started, the reasons
Figure out what has brought the device into a faulty state by disassembled it. You need to do this carefully and carefully, inside there are many small details that are easy to break. There are 2 types of damage: mechanical, electrical. Consider the most popular reasons why the lawn mower does not start and stalls:
- Carburetor failed;
- bolt compounds were shaken;
- Motor breakdown;
- jam the moving components of the mechanism (crankshaft, piston);
- Blocking a cutting tool (cylinder) by an alien object. branches, sticks, hard grass, stones, etc.;
- The oil supply and fuel supply system is disturbed;
- The light of the ignition failed;
- stretched out, the belt broke;
- a small or too large gap between the details inside the structure;
- faulty device switch;
- Dirty fuel hose, ventilation grilles;
- Cunnered air filter.
With prolonged use of a gasoline lawn mower without a break, the device stalls. Why the lawn mower stalls and does not start hot? The engine is overstrain. It is better to lay off the mowing, let the lawn mower be standing, after it has stalled, most likely the reason lies in the overheating of the device.
In some cases, this is a temporary phenomenon after the motor has cooled down, the equipment can work again. But still, you should not go out for hours. With active use, the life of the equipment is reduced. On average, repair is required 4 years after the purchase of goods.
When starting such a technical unit, some problems may arise, and in order to understand why the lawn mower is not launched, it is necessary to identify the causes, and for further work. eliminate them.
The main reason for the non.betrayal when starting the lawn mowel may cover that there is no gasoline in the fuel tank or its number is not enough to work the device. In this case, it is obvious that it is necessary to do. to refuel the tank with fuel, and in order to prevent such a situation, it is necessary to check in advance the presence of gasoline.
Non.compliance with the rules for the preparation of fuel mixtures, as well as the use of poor.quality raw materials in order to save finance can also lead to errors when starting and when working on a lawn mower. The way out in such a situation is simple. it is necessary to carefully choose the finished fuel, as well as carefully observe the proportions with your own preparation of mixtures.
Errors when starting can occur due to the fact that fuel can pour spark plugs. This is due to prolonged exposure to the launch cable with a closed air damper. To prevent this, you must always check it and, if necessary, return to the correct position.
Naturally, in the case of launching the lawn mower when the ignition is turned off, you may fail, since without this the functioning of the device is impossible.
Therefore, immediately after putting the air damper in order, do not forget to turn on the ignition, and only then can you safely start work.
Adjusting the gasopyle carburetor
This procedure is necessary specifically in cases where the economic garden tool does not start or, after starting, immediately stalls. The settings of the chainsaw carburetor are also needed when its power has fallen or the amount of fuel consumed has grown noticeably.
For independent implementation, the adjustment each manufacturer includes in the set of its garden equipment adjusting screws. The bolt indicated by the letter H serves to adjust the position of the chief jet and the operation of the internal combustion engine at high speeds. Bolt L is necessary for the basic settings of the position of the built.in idler nozzle created by the engine. Accordingly, the screw T requires the owner of the chainsaw to quickly adjust the operation of the factory engine at idle. In some cases, this bolt is also marked with letters S or LA.
How to adjust the carburetor on a chainsaw correctly?
Before you configure the carburetor on the chainsaw, you need to carefully prepare for the procedure. First of all, it is necessary to find the description of the rotation angles of adjusting screws in the operating manual for the operation. If you arbitrarily turn the bolts without adhering to the instructions of the manufacturer, this can lead to a serious breakdown of the ICE of the tool.
The motor itself should be in a completely good condition. Before setting, you also need to carefully clean the air filter. Otherwise, he will not be able to pass the air in the volume required to enrich the fuel mixture, which will lead to improper tuning the carburetor.
The control of the node should be performed on a flat surface. The saw itself should be installed in such a way that its saw headset is located away from the legs and face of the operator. Immediately before setting, you will need to remove the upper part of the protective plastic body of the tool, as well as extract foam rubber and part of the standard air filter. A thin figure screwdriver is required to perform the assembly of the node.
Dirty air filter
After prolonged operation, the air filter is polluted. This impedes uninterrupted work, leads to the fact that the mower stalls. Dirty air filter must be cleaned or replaced.

The reason for the stopping of the engine can be a malfunction of its parts. The lawn mower with a dry or flooded candle will not work. Remove it, clean it, check on a spark. If the part is working, get to work. If it is broken, replace with a new.

It does not develop speed
If the engine is solid, but at the same time the one.based tractor does not develop speed, then it is possible:
- The air filter is clogged. As a result, not all air enters the carburetor, and the fuel turns out to be oversaturated;
- low.quality fuel fluid;
- Flash in the incendiary system fail. As mentioned earlier, it is necessary to check the candle, fix the gap between the electrodes, pay attention to the mechanical integrity of the electrocope;
- if necessary, clean the carburetor and correctly adjust it;
- The work of the pistons and cylinders is interconnected with the power of the motor.
Therefore, pay attention to the state of the pistons and cylinders. Their external damage can significantly reduce the value of compression.
For example, carburetor cleaning can solve the problem
Motoblock malfunctions. why stalls, do.it.yourself repair
The same.based tractor is a useful economic unit, which greatly simplifies land and adjacent work. Like any other technique, units can break. But it is quite possible to repair the engine engine engine with your own hands, following simple recommendations.
The problem is when the same.based tractor works with periodic swallows and does not develop speed. almost the most common among gasoline and diesel units. If the unoic tractor starts and stalls, the main causes of this phenomenon should be sought in the fuel and incendiary system, the malfunctions of which can occur after 5 minutes of work.
If the unoic tractor does not develop turns and stalls spontaneously, you must check:
- Aerofilter. when it is clogged, it is cleaned by its surface, washed or blown with a vacuum cleaner.
- quality of the refueling fuel;
- incendiary system. its diagnosis begins with a candle, by the external state of which they judge the functionality of the ignition.
In addition to the candle, other ignition breakdowns are:
- irregular gap between the electrodes;
- mechanical damage to the electrocope;
- Unresolved angle between the magnetic part and the reel.

Do.it.yourself repair is allowed if it is provided for by the user’s guidance for a particular motoring model;
- Milter. the motor stalls at work and does not develop momentum due to the fault of the clogged muffler. To free it from combustion products, it is soaked in water with detergents and after washing. it is dried;
- a carburetor, the configuration of which may be incorrect;
- cylindrical details, due to which the motor does not develop speed under load. This can only be checked by a compressometer.
It also happens that the cultivator stalls sharply when tilted in both directions or only left or right. Most often this occurs due to the fault of the insufficient oil level. At the time of inclination, the lubricant residue sensor in the crankcase can be triggered, which automatically blocks the motor.
Air filter pollution
The air filter provides effective air purification, which penetrates the system and supports the combustion process. Over time, mud, extraneous impurities accumulate on the filter element, which negatively affects the functioning of the device. The lawn mower will often stall and hardly start up. To solve the problem, you need to clean the air filter or install a new.
Often, the refusal of the tool is associated with malfunctions and ignition system. If the candle is flooded with oil or completely dry, the engine will not work. It is necessary to remove the element, clean it and put it back to the seat. Do not forget to check the candle on the spark.
Low oil level
The performance of the lawn mower provides elements that rub with each other. Motor oil is used to reduce friction and slowdown in the system. Lack of lubricants can lead to complex breakdowns, up to jamming of the engine. Before each launch, measure the oil level using a special probe. If it is lower than the minimum, share the lubricant to the desired mark.
In some cases, the problem is why the tool is not started, you can solve it yourself without outside help. The solution will depend on the reason.
- Cleaning air filter. This element must be cleaned regularly, preferably after each working cycle or before starting work. Various particles accumulate on it that worsen his work. Try to turn on the device without a filter. If it works, then the problem is in the filter element.
- Fuel replacement after winter downtime. If the tank has fuel remained since last season, just drain it and pour a fresh gasoline mixture.
- Changing the position of the air damper. At the first launch, it should be in a closed or middle position, with repeatedly. in the open.
- Shaking the piston or knee shaft. The details can be crushed, gently twisted them from side to side.
- Cleaning the saapun. This element is responsible for supplying fuel to the system. If it is polluted, the fuel-lubricant mixture does not come. To start the tool, you need to clean the sapphone.
- Cleaning the spark plug. In the process of working, dirt accumulates on it, soot is formed. The candle needs to be removed from the seat, dry well, peeled with a file. You should also dry the candle hole. If the candle is very contaminated and not cleaned, it is better to install a new part.
Dismantling and assembly of the tool should only be carried out using special tools (keys of the corresponding size, screwdriver). If the lawn mower does not start even after performing the above actions, contact the service center.
Before working with any faulty device, you need to conduct a visual inspection. one that does not require a complete disassembly of the device. Agree: it is much easier, for example, to check the battery of the phone, the screen of which sharply stopped working, attaching it to the power, instead of completely disassemble the display, check the train, etc. D. So:
- First of all, we check whether the required amount of gasoline is available inside the motor. If the reason is this, then the rest of the actions do not need to be performed (and so similarly with each paragraph).
- We look at the possibility of gasoline or oil. You need to do this in good lighting or just use a flashlight.
- We look at whether the motor has external deformations.
Common reasons and ways to solve.
Frequent problem. air filter pollution. Take it off. If without it the motor starts to work better (this can be determined by sound), then the reason is found. If when the hand is closed with the hand, the engine reduces the speed, then this additionally confirms that the case is in the filter pollution. It is recommended to replace it with a new. You can also clean it with a vacuum cleaner or rinse thoroughly with a rag using a dishwasher or the same soap. The main thing is a thorough subsequent drying. After you need to very carefully grease the filter with oil and leave it for half an hour to absorb.
If the engine works, but reduces the moment, perhaps the blame for the ignition. The problems with this element are also evidenced by a large fuel consumption. You can check it using a special “gun”, which is sold in any automobile store. To do this, insert the candle into the hole. If after that there is no spark, then the element does not work. you just need to buy a new one and replace.
Check the sapun. This is a part of the engine that serves to maintain the same pressure in the gas tank. If it clogs, then, most likely, a vacuum will be created, which prevents the fuel further. To check, you need to dismantle it, and then close the hole with your palm in which there was a saopan. If there is no pressure, then the matter is in it. After cleaning the bacon yourself, mount it back. If the motor has not started to work, it may be in the rings. They should be checked using a compressometer. Before checking, warm the power unit: if there is not enough atmosphere, we change the ring.
Fairy tap breakdown can also indicate problems with the engine. Its deformation is very easy to see with an external examination of the part. If it is broken, replace it. To check, first of all, you need to disconnect the spark plugs wire and fix it away from the candle itself. Remove the casing, unscrewing the bolts. Install the filmmaker of the flywheel, remove it with the veneer. If deformation is detected, the spare part is replaced.
If the motor starts up, but immediately stalls, then this may indicate a damaged insulation of the ignition system. So, touching the metal of the case, the current passes further, there is a closure that extinguishes the spark.
The problem can also lie as fuel. First of all, you need to check if there is an excess of oil, then. gasoline itself. On the fuel in no case should be saved! You can check its quality in three ways:
- By color. To do this, pour fuel into a small transparent jar. If at the same time the color of gasoline is pale yellow, then it is in perfect order-exactly the one that is needed is chosen. If the shade is different, it can talk about cheap impurities. They quickly spoil the engine, which means that it will have to be taken to the nearest service center.
- Consists in the use of potassium permanganate. We also pour into a jar, dilute with potassium permanganate. If the fuel quickly repainted pink, this means that it has a large amount of water that should not be.
- Drip a little gasoline on a sheet of paper. Wait a couple of minutes: if it has not completely evaporated, and the paper changed its color, impurities are present in the fuel.
If the lawn mower smokes strongly, this may also indicate gasoline prepared for two.stroke engines. The next time you just need to choose it wisely, and before that it is worth changing the spark plug.
If the shaft does not rotate, then the problem in the “oil starvation” is a lack of oil in the engine. In addition, insufficient oil is used. To repair the crankshaft, a complete dismantling of the pallet should be carried out. You need to replace the bearings. Additionally, it is recommended to clean the channels if there is dirt in them. She can also negatively affect the lack of oil to lubricate parts.
If the candle is wet, problems with the carburetor are possible. When wear out gaskets, they should be changed. You also need to rinse it by partial disassembly. First remove the air filter and cover. After we extract all the contaminated elements, completely wash them so that they look like new. After we collect everything back. Details must be soaked in cleaning liquid, which can be bought in the store. It is also permissible to replace it with clean gasoline or kerosene. If necessary, the carburetor can be blown.
The above recommendations in most cases help to cope with a trimmer malfunction. However, it should be noted that it will simply simply be given the device to the service center.
