Lifan Unoa Tractor is not started no spark. Reverse

Why there is no spark on the cultivator. What to do if there is no spark when working? Repair of the ignition system

The ignition system refers to the list of the most important nodes of both corporate and home.made walk.behind tract. Its main function is to generate a spark, which is needed to ignite and gradual combustion of fuel in the chrome ICE cylinder.

The simplicity of the factory device of the assembly allows you to perform your own ignition of a motor block, which, most often, consists in setting a gap between its elements. However, to do this correctly, you need to study the design of the node.

The ignition device of any household agricultural load includes a coil, which is originally connected to the electrical power supply of the system, as well as magneto and candles. During the launch of the power unit, the voltage is supplied, as a result of which a pronounced spark is formed between the magnetic “shoe” and the standard candle. It is necessary for instant ignition of fuel, which at this moment is in the combustion chamber of the motor. In more detail about the structure of the ignition system of the used motorblock will tell the photo.

The electronic ignition system of the walk.behind tractor is also often equipped with interruptions that work in automatic mode when any of the malfunctions of the node appears. This leads to an emergency shutdown of electric power supply on the network.

Frequent causes of ignition system breakdown

Often, the Mole motor cultivator cannot be made due to a number of other malfunctions, all of them are associated with the ignition system of the unit. The breakdowns include:

Lack of spark. this indicates a malfunction of the candle and the need for its urgent replacement. Often the cause of this malfunction is a violation of the clearance between the ignition coil and the magnetic wire;
Another often breakdown is a violation of the connection of a gasoline hose. It will be necessary to carefully examine this element and check its fastening with other nodes of the cultivator;
The next malfunction is to contact the wire of the magneto and the plate of the fly wheel. You will need to achieve a gap between these elements.

Repair of ignition coils and elimination of malfunctions

There are situations when the motor.cultivator does not start. Perhaps this problem is related to the coil system. For example, there is:

Malfunction in the coil itself.
Malfunction in the candle in the coil.
In the wiring.
In the tip of the candle.
To check the candle, you need to pull it out and inspect it. If there is a case on the electrodes, then they can be warmed with gas.

To check the magneto (coils), the tip is put on the candle and bring the lower part to the coil. When rotating the flywheel, a spark should form. If this does not happen, then the malfunction in the ignition coil for the walk.behind tractor.

Malfunction in the engine

If the cascade unoic tractor does not start at all, then the cause of the breakdown can be hidden in the engine itself. If there is too much fuel, then the candle becomes wet. To eliminate the breakdown, it is necessary to disassemble and dry the cylinder. First you need to block the fuel supply. After drying, you need to turn out the candle and use a hand starter, turn on the engine. If nothing changes after these actions, then you need to seek help from professionals.

Another reason why not. there may be insufficient supply of gasoline into the carburetor, which we talked about a little higher.

If your walk-behind tractor is an electric starter, then in this case it may not start due to a simple battery discharge. If the malfunction is associated with the starter itself, in this case you can not do without the help of specialists.

What elements of the machine can require the close attention of the operator?

Now let us consider in more detail all those malfunctions that can affect the operation of the unit to whatever model it belongs.

Does not start

So what to do if the “mole” does not start, what reasons may be. Junk, or completely absent ignition in the following cases:

There is no spark. This may mean that the light of the ignition has burned down. In this case, it is necessary to unscrew it and simply replace it with a new working.
The light of the ignition has smoked. It will return it to life good cleaning (remove the soil, clean contact), after which the candle must be thoroughly rinsed in gasoline.
If the cultivator does not start, but there is a spark, then most likely the reason is the lack of isolation. Look at the candle again, in this case it is wet or slightly wet. You can not change the entire candle, you need to replace only the tip.
Poor.quality fuel can be the reason for the lack of ignition of a cultivator. It is for this reason that the spark will get rid of, after which you will have to change the tip.
Fuel flowing from the candle is another reason why the car does not start. To straighten the situation, it is necessary to drain the cylinder, pumping the engine using a manual starter.
The reason for the lack of ignition may be problems with the hoses that supply fuel. To restore the operation of the motor.cultivator, you must either carefully pull the hoses, or, in the case of a break, replace them with new.
Poor isolation of the electric system (high.voltage and low.voltage wires) can also cause the unit not started.
Pay attention to the air filter. If it is contaminated, then the ignition problems are provided. It is necessary to either clean it or replace it. Most often, they resort to the second option, good, this spare part is available both in price and in the store.
The failure of the Magneto himself. This part is not subject to repair, immediately replaced by a new. How to check the Mart cultivator Magneto to make sure its malfunctions? Yes, it is very simple. if all the reasons why there may be no spark are excluded, then the cause of the malfunction is in Magneto. Many craftsmen redo the working magneto, thereby increasing its resource.

This is what the ignition scheme of the magneto for the MROT motor.cultivator might look like

The ignition may be absent if the plate of the flywheel shake magnet pipelines of the magneto.
Incorrectly exhibited gap between the electrodes will not let the spark.

Engine

The main reasons that the Mole motor is not started is:

lack of fuel (or its low quality);
ignition problems discussed above;
the appearance of decompression and, as a result, wear of the piston, deformation of the exhaust valve.

In the first case, it is enough to simply pour the required amount of fuel (a mixture of gasoline with M-8V oil) and all problems will be resolved. In the case of compression violation, you will have to completely disassemble the engine and replace damaged parts, and this can be a piston, a sealing ring.

The deformation of the final valve becomes another reason for the compression violation, which first leads to the loss of the power of the MROT motor.cultivator, and then to the problems of launching.

To restore engine performance, it is necessary to complete its complete disassembly. Assessing the condition of the piston, if necessary, replace it. Change piston rings, exhaust valve. We examine the engine head, in particular the gas distribution mechanism, in the presence of a car, we clean it. In case of damage to the structural elements, we replace them with good.

Choosing a motor

In the Union, only two.stroke parlor engines of domestic production were used, which were not distinguished by a special power. Today you can find a “mole” with a four.stroke imported engine. But if your arsenal has the first cultivator model, then upgrading your “mole” by replacing the motor is completely easy.

And then a new question arises: which engine is best installed on the unit? It is easy to answer it. those models that are installed in more new machines are suitable for it.

It is best to replace the domestic engine with imported:

Any of them will not only give a new life to the motorbide, but will also significantly increase the power and resource of the unit.

An excellent solution would be the installation of the Lifan engine on the MROT motor.cultivator. Such a motor provides a long life for the car, because in addition to reliability and economy, the lifers stand out also unpretentious and will definitely not require additional attention to themselves.

Why the uniform tractor does not start, there is no ignition and the spark disappeared, how to start a motor.cultivator. reasons

If you are looking for an optimal value for price and quality, we recommend that you pay attention to the domestic one.based mole tractor, which has been released from 83 years old. The same.based tractor is produced today in the Omsk Machine.Building Plant. In recent years, high.quality technical characteristics allow him to successfully compete with many foreign units. But there are also moments when you do not know why the one.legged tractor of the mole does not start or it starts poorly or there is no spark in it. It may be necessary to repair the starter, and maybe the ignition may fail faultly. In general, with this question and reasons you should carefully figure it out.

Motoblock device mole

Motobobes, which were characterized by simplicity of the design, began to be produced for more than forty years. The first models were equipped with an insufficiently powerful engine and could only be used in a narrow spectrum of work.

The first Mole buyers were not very pleased with the insufficient power of the power unit, as a result of numerous complaints, the same.based tractor began to improve. To date, the Mole model is the most successful and universal model of domestic cultivators, among all presented on the market.

Small in parameters, it can be used for different purposes: weeding, loosening, harrowing, alignment. The same.based tractor can be used even on a small land plot whose area does not exceed 10 acres.

Motoblocks Mole, Carver, Champion, Lander, Pro, Huter, Don, Sadko can be used with a variety of line of additional mounted devices.

In the standard configuration to the mole you will be provided with a coupon and a cutter. Additionally, you can buy a plow to plow the ground, a dug for potatoes.

What are the main advantages of this unit?

Simple design,
high efficiency,
affordable price. This contributed to the fact that the model became insanely popular among domestic buyers,
There is nothing superfluous in the mole, so he regularly copes with all the tasks set before him.

How to set the ignition

You can set the ignition thanks to these methods.

Use a strobe

It is worth warming the engine to temperature, which is optimal for work.
Make a strobe.slope power connection to the walk.behind tractor network.
The sensor is responsible for the triggering sound must be placed on a high.voltage electric wire of one of the cylinders.
Remove the vacuum-correctional lunch and drown out it.
Strobe.strobe light must be directed to the pulley.
Make the motor, the turns should be idle.
Turn the trimbler case.
Create a fixation during which the pulley label will reach the necessary mark on the lid of the apparatus.
Fix the mounting nut.

Using a lamp

It is necessary to turn the crankshaft to the position during which the pulley mark will reach the necessary mark on the gas distribution mechanism, while the runner responsible for the interruption and distribution of the ignition should show on the high.voltage wire of one of the cylinders.
Reduce the strength, which fixes the nut of the Trambler case.
Connect one of the wires for control to the metal wire, which serves to transmit electric current, which goes from the breaker-distributor to the incendiary coil, and the next wire to the “mass” of the walk-behind tractor.
Turn on the ignition without fail.
The case of the mechanism that determines the moment of the formation of high.voltage pulses in the ignition system, rotate the watch arrow, do this until the lamp stops burning.
Slowly, turn the breeder-distributor in the other direction.
Create fixation for an interrupter of the distributor, while the light bulb should occur to control.
Tighten the nut, which serves to fasten the trambler.

With the help of a spark

The crankshaft should be turned to a position during which the cone label will be identical to the same mark located at the base of the gas distribution mechanism, and the interruption-distributing runner will show on the high-voltage wire of one of the cylinders.
Reduce the fixing power of the nut, which retains, there was a case of a mechanism that determines the moment of the formation of high.voltage impulses in the ignition system.
From the cover of the mechanism that determines the moment of the formation of high.voltage pulses in the ignition system, it is worth extracting the high.voltage wire, which is located in the center, and its contact must be placed in distance 0.5 cm from the “mass” of the motorcycle unit.
Do not forget to turn on the ignition.
The case of the mechanism that determines the moment of the formation of high.voltage pulses in the ignition system should be turned on the arrow of the clock for 200.
Slowly cram the mechanism, which determines the moment of formation of high.voltage pulses in the ignition system to the other side.
The position of the mechanism, which determines the moment of the formation of high.voltage pulses in the ignition system, should not move. At the same time, between the contact of the wire, which is located in the center and the “mass” will arise a spark.
It is worth tightening the interruption nut.

You can hear it

Turn on the motor.
Loosen the nut, which fixes the trambler base.
Slowly cram the interruption case on two sides.
The position of the mechanism, which determines the moment of the formation of high.voltage pulses in the ignition system, must be fixed in the position where the power of the motor is the most stable, and the speed. achieve the maximum level.
The body of the interrupter must be turned on the watch arrow.
Fix the tile.

Malfunctions and causes

If the motor blocks of mole, Forza, Viking, Crosser, Prostrab, Texas, Patriot, Caiman do not start and stalls or the spark has disappeared in the ignition system, this means that you did not carefully monitor the engine ignition system. You must conduct weekly:
