Gasoline appeared in the tiller‘s crankcase
Fuel, regardless of the type of internal combustion engine power system, after the gasoline pump must reach the carburetor and the combustion chamber. The latter is a section between the cylinder head (cylinder head) and the piston head, where a mixture of fuel and oxygen is combusted. A mixture of fuel and air on the way to the combustion chamber passes through the intake channels, their necks are always lubricated with motor oils. This is where leaks happen. The reason is that the valves are equipped with a rubber cap. They are designed to reflect car oil. If, due to the strong wear of the caps, grease penetrates into the combustion chamber, the car exhaust will stink of smoke from motorcycles. The chance that the oil will get into the combustion chamber is rather low. Usually the oil smells like gasoline for other reasons.
It should be added that if the car starts up in winter conditions, gasoline will be burned ineffectively for the first couple of minutes. Exhaust gas smells like raw fuel, condensation is flowing from the exhaust pipe. This is completely normal.
Third: starting the engine.
When the engine is started for the first time or cold, there is an increased load on the piston system. High revs can damage the motor. Therefore, it is necessary to start the motor at 1/3 throttle position. And you need to run in at medium speeds.
Injection nozzles
In an engine with an injector, the smell of gasoline coming from the dipstick indicates a breakdown of the injectors and the ignition system. In the first case, we are talking about the fact that the nozzles lose proper tightness. After the engine is turned off, due to the final pressure, fuel seeps into the manifold, from there it enters the cylinder block. The piston rings serve as a barrier to the crankcase, however, if they are worn out, gasoline will still get there.
Gasoline also smells with a faulty ignition system. If the spark plug is broken, the fuel does NOT flash in the cylinders of the block, that is, it is wasted just like that. To eliminate the problem, you need to remove the fuel rail, in turn, check the tightness of all injectors by supplying kerosene to them under pressure. Leaking parts and broken plugs must be replaced with others.
Eliminating the problem
When you smell gasoline in the oil, it is usually recommended to go to a car service. If things have gone too far, second exit comments.
However, at the beginning, when there are no significant car malfunctions, the driver has the opportunity to fix the problems on his own. To do this, you need to quickly drive a couple of kilometers by car, then drain the lubricant, check if there is gasoline in the oil. If it is not there, then you managed to get rid of the smell of gasoline.
Foreign manufacturers recommend diagnosing the car in this way. I often go to the highway to dump excess fuel. Thanks to this, you will be able to get rid of the problem at the very beginning, prevent the occurrence of significant damage. You will NOT have to spend money on expensive repairs.
Leakage signs
Is it possible to understand that there was a leak? You can find out about this by noticing a dark puddle under the car. It happens that the grease flows out from under the valve cover lining, oil seals or crankcase gasket. Car oil can only be mixed with fuel in the engine. It is possible to determine that gasoline has got into an oily liquid by the following signs:
- The viscosity of the oil has changed, it has become thinner;
- Car oil on the dipstick lights up if you bring a flame;
- A drop of oil on a piece of paper leaves a greasy, enlarging stain.
Fuel in the lubrication complex
The owners of both foreign cars and Russian cars are aware of the problem of the smell of gasoline from car oil. In a two-stroke power unit, the fuel is a combination of gasoline and lubricant. In a four-stroke engine, these fluids must NOT be in contact. The oil circulates closed. If there is a smell of gasoline on the dipstick, it means that the fuel has mixed with the car oil.
If the Tillery, swim, turnover! Tiller Neva MB 2 swim rpm
Tiller. One of the most useful household units. Even a simple and not very powerful machine can significantly facilitate the care of the garden and the surrounding area. However, tiller. This is a technique that characterizes the Salesman Riot. Let’s look at the most common breakdowns of an agricultural unit, their causes and methods of elimination on our own.
Frequent malfunctions and their causes
To the main features of temporary malfunctions of brand tilers Neva MB 2 and Neva MB2K, in which usually swim beginners, the following should be attributed.
- The valve belt is incorrectly adjusted, it flies out. The back and forth movements in the tiller are carried out using a V-belt. If the drive belt slips off, the unit will not work correctly. You can determine the desired length and width by measuring the segment from the pulley to the rollers. It is recommended to select the following parameters: width. 0.75 cm long. 0.65.
- The device stalls under high load. Incorrectly functioning oil seals can cause breakage.
- Incorrectly adjusted carburetor system, unit Will not start. Before carrying out this procedure, always adjust the centrifugal regulators using the supplied instructions.
- Ignition not exposed, gears are poorly included. The cause of a breakdown may be the absence of a spark, which provokes the ignition of fuel in the internal combustion chamber.
- Malfunctions with candles, the muffler shoots and smokes, black smoke goes. It is possible that the unit cannot continue to work precisely because the candles are faulty, you must make sure of this.
Why Tiller Shoots the Silencer?
Often, when working with an agricultural unit, loud uncharacteristic sounds from the muffler are clearly audible. At the same time, the tiller also smokes heavily and stalls. To be able to fix a malfunction with your own hands, you need, first, to determine its essence.
Most often, a tiller shoots a silencer 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 exposed 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 tiller’s ignition system;
- Incomplete combustion of fuel in the engine cylinder. Repairing a tiller engine in this case means disassembling the piston group, thoroughly washing and drying the engine cylinder, and adjusting the tiller carburetor.
Repair of all of the above breakdowns does not require special skills and great experience. The most important thing. Proceed strictly in accordance with the operating instructions for the agricultural machine.
Snow-white smoke pours out of the tiller, begins to work in buckwheat.

The material will be updated, we are waiting for comments with questions, stories about identifying this or that malfunction and methods for its elimination. Also, see the answers to questions on this or that model of the tiller on the page of its description.
Tiller engine does not start well when hot
The question of why the tiller motor stalls when heated is quite simple to solve. The whole point of the problem lies in the excess air supplied to the tiller’s carburetor. 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 the temperature of the engine of the unit. This problem is observed only during the tiller operation. 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 tiller carburetor, the remaining fuel begins to actively evaporate.Fill all the voids in the tiller device, including the air filter and the intake manifold. This leads to the complete disappearance of fuel, due to which the tiller does not start when the engine is heated.
To fix this problem, you need to every time you start the tiller on hot act in a specific algorithm. Your main task. Achieve the 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 engine flooding;
- After several attempts to start with the throttle trigger half pressed, you will start the tiller engine, 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 tiller will NOT be subject to excessive wear.
All of the above methods will help to effectively cope with Typical breakdowns of the most famous tiller manufacturers. They are equally successfully used by the owners of agricultural units of the brands Honda, Agro, Kaskad and Neva.
In this topic, we will get acquainted to disassemble malfunctions of tillers and cultivators of all brands, Hey. Neva, Bison, etc., and elimination of THESE defects and repair. Most of the problems are common to all types of tillers, their engines and other nodes.
It often happens that a previously serviceable tiller that has served for a couple of years suddenly loses power.
