Motoblock Engine Shoots At The Silencer

In this section, we will analyze the malfunctions of motoblocks and cultivators of all Salyut brands. Neva, Bison, etc., and their elimination and repair. Most problems are common to all types of motor units, their engines and other components.

Engine power has dropped

It often happens that a previously serviced single-axle tractor that has been in service for several years suddenly loses its power.

Motoblock foggy smoke

White smoke pours from the walk-behind tractor and starts working in the “chow”.

Why is a single axle tractor intermittent??

Despite the durability of the motor part, it is not protected from malfunctions. The appearance of extraneous noises, jerks, pauses in her work are the main evidence that she needs urgent diagnostics and repair.

If the cultivator periodically stalls and does not develop speed, this may be due to:

insufficient warming up of the motor unit, which works in jerks. A diesel, like a gasoline cultivator, takes at least 10 minutes to warm up;
a break in the starter cable, which is replaced with a new one instead of repair;
loosening the screw ties between the starter and the motor;
ratchet malfunctions, which prevents the normal operation of the starting block;
failure of the cylinder and pistons;
low-quality gasoline, due to which the engine does not develop revs, does not develop revs and hits the return line. The situation can be corrected without repair: after flushing the fuel tank and hoses, they simply switch to new fuel.

It also happens that the engine “does not pull”, which can be traced by the overall productivity of the device.

clogging of filtration components;
breakdown of magneto ignition.

Why is a single axle tractor intermittent??

There are other issues worth considering:

The motor-block engine hits the return line. The reason is often the use of poor fuel. It will not be enough to replace the fuel. The pump and fuel supply hoses are flushed;
The technique works in jerks. The engine does not fully warm up. The motor must be turned off, wait for it to cool completely. Then restart it and warm it up for at least ten minutes;
The engine does not pull, therefore the engine power decreases. The filter system is checked and cleaned. The problem can be provoked by wear of the magneto ignition. In this case, the part is replaced.

Owners of both gasoline and diesel vehicles may face such problems. Regardless of the specifics of the breakdown, you urgently need to stop using the unit and start fixing the problem.

a uniaxial tractor starts up and stalls: causes of malfunction and mechanisms for their elimination

The owners of either completely new or used cultivators are not insured against a situation when a single-axle tractor starts up, but immediately stalls at idle.

It can be caused by a number of factors:

problems in the ignition system:
discharge or breakage of electrical contacts;
spark plug malfunction. They can be installed only after unscrewing and external inspection. If the candle:
dry. the cause of the malfunction lies in the carburetor, where gasoline is not supplied. It can arise due to the clogging of its filter or a separate nozzle;
wet. the engine does not develop speed due to an excess of fuel;
covered with carbon deposits. the fact of its failure, due to which an incendiary spark could not form. Checking with electrodes will help to make sure of this;
after replacing or cleaning the spark plug, the electronics are examined. the integrity of the connections and the wires themselves, which, due to strong vibration, may need to be repaired;
shortage or poor quality of fuel. Often, the engine does not pick up speed due to improperly prepared fuel mixture or debris in the carburetor. In this case, the repair begins with removing it from the walk-behind tractor body and cleaning it from dirt particles. In parallel with this, the fuel is changed, previously draining the old one and rinsing the fuel tank and supply hoses.
Another reason that a single-axle tractor starts up and immediately stalls, associated with gasoline, may be the depressurization of the gas tank itself. This is very often observed after a long downtime (for example, after a winter), when a single-axle tractor has not been used for a long time and was stored with gross violations. After repairing or replacing the entire fuel tank, the device’s operability is usually restored;
cool weather, due to which diesel equipment often stalls. Therefore, in early spring, experts advise turning on a uniaxial tractor only after pouring hot water into the radiator;
malfunction of the gearbox. The fact that the cultivator does not develop speed and stalls at idle is evidenced by the characteristic knock from the gearbox, which occurs against the background of a lack of lubricant.

The engine of the walk-behind tractor does not start well when hot

The question of why the motor of the walk-behind tractor stalls when heated is quite simple to solve. The whole essence of the problem lies in the excess air supplied to the carburetor of the walk-behind tractor. Part of it is mixed with a mixture of gasoline and engine oil, and the second part cools the carburetor. As a result, the temperature of the carburetor becomes much lower than that of the engine of the unit. This problem is observed only during the operation of the walk-behind tractor. When its engine is turned off, the carburetor, on the contrary, lends itself to heating from the side of the hot walls of the engine.

During the heating of the carburetor of the walk-behind tractor, fuel residues begin to actively evaporate, filling all the voids in the walk-behind tractor device, including the air filter and the intake manifold. This leads to the complete disappearance of fuel, due to which a single-axle tractor does not start when the engine is heated.

To fix this problem, it is necessary to act in a certain algorithm every time the walk-behind tractor is started “hot”. Your main task is to achieve a combination of the mixture so that the engine can start. This will require:

In the process of starting a hot engine, squeeze the gas trigger halfway;
Do not try to pull the gas trigger over and over again, otherwise this will only aggravate the situation, since during frequent pressing of the gas trigger, the fuel pump will supply new portions of fuel to the carburetor, which will lead to flooding of the engine;
After several attempts to start with the gas trigger half pressed, you will start the engine of the walk-behind tractor, after which you will need to gas it 2-3 times and continue working.

This procedure will eliminate the increased load on the hot motor, due to which the main parts and mechanisms of the walk-behind tractor will not succumb to excessive wear.

All of the above methods will help to effectively cope with typical breakdowns of the most famous manufacturers of walk-behind tractors. They are equally successfully used by the owners of agricultural machinery brands Honda, Agro, Kaskad and Neva.

Reasons why a uniaxial tractor won’t start and how to fix them

There are several reasons why motor vehicles do not start when starting. These include:

Damage to the carburetor (in motoblocks with a gasoline engine);

Malfunction of ignition / glow devices;

Low lubrication level.

When strange changes appear in the cultivator and its operation becomes unstable, the carburetor is first checked. In this important unit, a fuel-air mixture (FA) is formed and dosing for feeding it into the cylinders of an internal combustion engine (ICE). And if the jets become clogged, the fuel system becomes obstructed, as a result of which the carburetor loses its ability to start the engine. To eliminate the malfunction, the fuel line is repaired, which involves a partial disassembly of the carburetor, flushing the pump, blowing the nozzles through the fuel nozzle.

Sometimes the reason that a single-axle tractor will not start is a malfunction of the spark plugs, which play an important role in starting a carburetor ICE, or glow plugs that ensure the start of a diesel engine. If the fuse devices become wet, which happens due to the throwing of their fuel assemblies, then a spark begins to disappear on them. In the absence of sparking, ignition of the air-fuel mixture does not occur, and therefore the engine cannot be started. This problem can be solved in different ways:

Make minor repairs and replace non-working candles with new ones;
Burn “flooded candles and use fire to clean them of traces of gasoline.

Motorized equipment does not start due to the fact that damage to the glow plugs occurs. In a diesel engine, fuel is ignited by contact with hot air, which is heated in the cylinder by compression by a piston. This happens without any problems when the diesel engine has already warmed up and the operating temperature in it is maintained by the heated cylinder walls. But in cold weather, and especially in winter, the engine is warmed up using glowing devices and if they are out of order, it will not be possible to start a single-axle tractor.

If, when inspecting a carburetor engine or diesel engine, no defective spark plugs were found, but the problems remain, and they are also accompanied by popping into the muffler, you should check the operability of all devices responsible for the flammability of the fuel. A malfunction in them can also be the reason that a single-axle tractor will not start. Diagnostics is best done in a service center, where professionals will find the cause of the damage and competently carry out repairs.

Motorcycle equipment will not start even with an insufficient level of lubricant in the motor. Some models are equipped with special control sensors, which, in the event of a lack of lubrication, do not allow the engine to start. Particular attention should be paid to those machine variants that do not have such sensors. Sooner or later, the level of the lubricant mixture will reach a critical value and if it is not replenished to the norm, this will soon lead to wear of parts and, as a result, to overhaul of the engine.

Why does a single-axle tractor stall under loads?

A fairly common problem is that the equipment stalls after 5 minutes of work. Often the reason is a fuel supply failure and ignition problems.

If the equipment stalls during operation, you need to check how well the fuel is supplied:

The candle is taken out and viewed. It is overdried. this indicates a lack of fuel;
There must be enough fuel in the gas tank for the normal functioning of the machine;
The condition of the fuel cock is examined. It can simply be blocked. Sometimes it is enough to open it for further use of the unit.

a uniaxial tractor starts up and stalls if there is an ignition problem. First you need to check the candles. Wet items indicate breakage. It is necessary to re-adjust the ignition system of the technique.

How a Muffler Works

Reconfiguration is done as follows:

The cover is removed, which protects the parts of the ignition system;
The engine flywheel turns until the contacts open in the magneto;
A special feeler gauge measures the gap from the “anvil” to the “hammer”;
The flywheel turns until the piston is compressed. The latter must reach its peak;
The flywheel turns again until the characteristic knock, which will indicate the operation of the freewheel;
The flywheel turns in the other direction until the mark of this element coincides with the mark on the unit body;
The gap from the break contact to the cam is set at 0.3 millimeters;
The cam is fixed with a screw, which is located above the element, and the protective cover is installed in the body of the equipment.

If the above steps are performed correctly, the single axle tractor will not stall under load. When tilted, a vehicle may stall if there is not enough fuel in the gas tank. The unit must be installed straight, remove the starter rope. If the engine starts, you need to fill the fuel tank.

Repair: why a uniaxial tractor stalls under load, shoots at the muffler, works intermittently, and more

a single-axle tractor is one of the most useful household implements. Even a simple and not very powerful machine can significantly facilitate the care of the garden and the surrounding area. At the same time, a single-axle tractor is a technique that tends to break down. Let’s look at the most common breakdowns of an agricultural unit, their causes and methods of elimination on our own.

DIY motoblock repair

Unfortunately, any equipment sometimes fails, so its owner needs to be able to troubleshoot on his own. Of course, if the car is under warranty, it is better to take it to a service center, where specialists will carry out warranty repairs for free.

Oil In The Exhaust? What Causes It and How To Troubleshoot It.

Often damage to the cultivator, walk-behind tractor occurs due to improper operation. when bad fuel is poured, heavy loads are allowed or during the time they do not make up for the loss of lubricating fluid. Then the car starts to stall, “buried”, it is bad to gain momentum (especially if there is an electric motor on it), or even stops starting altogether. But, knowing the device of the unit and the principle of operation of its mechanisms, you can yourself identify the cause of the damage and carry out high-quality repairs.

uniaxial tractor starts up and stalls. reasons and repairs

Repair of walk-behind tractors in case they start up and, after a few seconds, stall, you must start by looking for the main causes of this malfunction. To do this, you need to inspect:

Candles, wires and electrodes. in most cases, the unit starts up and immediately stalls due to too large a gap between the electrodes of the ignition system, poor contact between the wires, as well as a dirty spark plug. Repair should begin with cleaning the spark plug. If this does not help, then you need to check the integrity of the wires. If this did not bring the desired result, then it will be necessary to re-set the gap between the electrodes of the ignition system;
Carburetor for contamination and sufficient fuel intake. If you have been using low-quality gasoline and have added too much engine oil to it, you will need to change the fuel and reduce the amount of oil. In addition, you need to dismantle, disassemble, and thoroughly clean the carburetor;
The presence of gasoline in the fuel tank. if a single-axle tractor is not picking up speed, then this often indicates a lack of fuel necessary for the engine to function properly. Very often, owners of walk-behind tractors are faced with a problem in which gasoline spills through a small hole or crack in the fuel tank of the car. In this case, you need to try to patch up the defect, and if it was not possible to do this, you will need to completely replace the tank of the walk-behind tractor.

Why is a single axle tractor intermittent??

Among other typical malfunctions of the walk-behind tractor, a number of such breakdowns can also be distinguished:

The motor of the unit hits the return line. this indicates the use of low-quality fuel for refueling the unit. In this case, you will have to not only replace the fuel, but also thoroughly flush the fuel pump and fuel supply hoses;
a uniaxial tractor works in jerks. the reason for this lies in the insufficient warming up of the engine. Be sure to turn off the engine, wait for it to cool completely, and start the engine again, giving it at least 10 minutes to fully warm up;
The motor of the walk-behind tractor does not noticeably pull, the engine power has decreased. in this case, you need to check and, if necessary, clean the air and fuel filter. Another reason for this breakdown lies in the wear of the magneto ignition system. It is best to replace the part immediately without trying to repair it.

Why a single axle tractor shoots a muffler?

Often, when working with an agricultural unit, loud uncharacteristic sounds from the muffler are clearly audible. At the same time, a single-axle tractor also produces a lot of smoke and stalls. To be able to fix a malfunction with your own hands, you need, first, to determine its essence.

The most common uniaxial tractor shoots at the muffler due to a number of the following problems:

Excessive engine oil in the fuel mixture. in this case, you need to drain the remaining fuel, flush the fuel pump and hoses, and fill in new fuel with less oil;
Incorrectly set ignition. if the mechanism works with a delay, then this leads to the appearance of atypical shots, which are clearly audible in the area of the muffler. In such a situation, you should immediately set the correct gap between the electrodes of the ignition system of the walk-behind tractor;
Incomplete combustion of fuel in the engine cylinder. Repairing a walk-behind tractor engine in this case means disassembling the piston group, thoroughly washing and drying the engine cylinder, as well as adjusting the carburetor of the walk-behind tractor.

Repair of all of the above breakdowns does not require special skills and a lot of experience. The most important thing is to act strictly according to the operating instructions for the agricultural unit.

Why does a single axle tractor stall under load??

Almost every owner of a walk-behind tractor, regardless of the brand and model of the agricultural unit, has encountered a problem in which a single-axle tractor starts up and stalls after 5 minutes of operation. The main reasons for this breakdown lie in the problems with the fuel supply and the breakdown of the ignition system of the machine.

As practice shows, if a single-axle tractor stalls during operation, then its owner should immediately inspect the details of the fuel supply system. First of all, turn out and look at the spark plug. if it is completely dry, then this indicates that fuel does not enter the engine cylinder. After that, you need to make sure that there is a sufficient amount of fuel in the fuel tank. If there is gasoline and it is enough for work. inspect the fuel cock. it is quite possible that it is in the closed position. To start the walk-behind tractor, just open the fuel cock and continue working with the unit.

Another reason why a single-axle tractor starts up and stalls after 5 minutes of operation is a breakdown of the ignition system. It is quite simple to determine that the unit is faulty for this very reason. take a look at the candles. if they are wet, it means that the malfunctions have appeared in the ignition system of the walk-behind tractor. The best way out of this situation is to re-adjust the ignition system of the unit. All actions, in this case, must be performed in this order:

Remove the cover that protects the elements of the ignition system;
Turn the flywheel of the motor until the contacts open in the magneto;
Using a special probe, measure the gap between the “anvil” and the “hammer” of the ignition system of the walk-behind tractor;
After that, turn the flywheel until the piston of the walk-behind tractor is compressed. In this case, the latter must reach its highest point;
Turn the flywheel again until you hear a characteristic knock. this means that the freewheel has worked;
Then turn the flywheel in the opposite direction so that the mark on it coincides with the mark on the walk-behind tractor;
Set the gap between the break contact and the cam. it should be 0.3 mm;
At the end, fix the cam with the screw located on top of the part, and install the protective cover back into the walk-behind tractor body.

Also, the household unit often stalls when tilted. This indicates an insufficient amount of fuel in the fuel tank. If you put the unit in a horizontal position, pull out the starter rope, and the engine will start, which means that you will need to add gasoline to the tank.

The engine of the walk-behind tractor does not start well when hot

The question of why the motor of the walk-behind tractor stalls when heated is quite simple to solve. The whole essence of the problem lies in the excess air supplied to the carburetor of the walk-behind tractor. Part of it is mixed with a mixture of gasoline and engine oil, and the second part cools the carburetor. As a result, the temperature of the carburetor becomes much lower than that of the engine of the unit. This problem is observed only during the operation of the walk-behind tractor. When its engine is turned off, the carburetor, on the contrary, lends itself to heating from the side of the hot walls of the engine.

In the process of starting a hot engine, squeeze the gas trigger halfway;
Do not try to pull the gas trigger over and over again, otherwise this will only aggravate the situation, since during frequent pressing of the gas trigger, the fuel pump will supply new portions of fuel to the carburetor, which will lead to flooding of the engine;
After several attempts to start with the gas trigger half pressed, you will start the engine of the walk-behind tractor, after which you will need to gas it 2-3 times and continue working.
