PREPARING THE MOTOR FOR OPERATION
Fuel mixture preparation
The engine runs on a mixture of motor gasoline with M-8V oil, (M-8A) GOST 30541-78. During the engine running-in period, the oil content in the mixture should be about 8% (by volume), that is, 0.8 liters of oil per 10 liters of gasoline, and during operation - about 4% (by volume), that is, 0.4 liters of oil for 10 liters of gasoline.
Mixing oil with gasoline must be done thoroughly in a separate clean container until the oil is completely dissolved in gasoline. Pour fuel into the tank through a funnel with a fine mesh.
Operating the engine with an insufficient oil content in gasoline is completely unacceptable, as it leads to engine failure. The increased oil content in the mixture makes it difficult to start the engine due to oiling of the spark plug electrodes, impairs the operation of the carburetor, leads to the formation of significant carbon deposits and increases the pollution of the water environment.
When using MC-20 oil during the engine running-in period, the oil content in the mixture should be about 6% (by volume), that is, 0.6 liters of oil per 10 liters of gasoline, and during operation - 3% (by volume), that is 0.3 liters of oil per 10 liters of gasoline.
Installing the motor on the boat
The motor is installed on a boat with a transom up to 384 mm high.
To install the motor on the boat, it is necessary to place it on the boat transom with clamps to the full depth of their grooves and tighten the screws.
The upper part of the gearbox housing must be at least 30 mm deep.
If the transom is high and a cutout cannot be made in it, then it is necessary to attach the motor to an additional frame.
To reduce propeller cavitation, it is recommended to install the upper part of the gearbox housing (anti-cavitation plate) 30–60 mm deeper than the lower part of the transom.
During operation, check the tightness of the screws. To facilitate boat handling, it is recommended to mount the motor as close to the middle of the transom as possible.
When installing the motor, it is necessary to ensure the horizontal position of the propeller axis (taking into account the position of the boat during movement) by repositioning the roller in the holes of the clamp.
Starting the motor
The motor is started in the following order:
1. Loosen the screw on the fuel tank cap 4-5 turns.
2. Open the fuel cock.
3. Fill the carburetor float chamber with fuel by pressing the float damper 19 (Fig. 3).
4. Set the tiller handle to idle (turn clockwise).
5. Make 2-3 jerks with the starting rope. First, with a smooth movement, engage the stop with the flywheel, then jerk it sharply. Do not pull the rope to the very end and throw it after starting.
After the engine has started, check for water leaks and let it run at low throttle for 3 minutes.
If the engine does not start, you need to check the condition of the spark plugs.
6. In case of a difficult start, it is recommended to warm up the motor without immersing it in water, but no more than 15 seconds.
Stopping the motor
To stop the engine, you need to reduce the engine speed to minimum, and then turn off the ignition by pressing the engine stop button. In this case, fuel remains in the carburetor and pipe, which must be drained when the engine is removed from the boat.
In cases where the engine is turned off for a long time, it is recommended to stop it by running out of fuel in the tube and carburetor. To do this, turn off the fuel cock. After running out of fuel in the carburetor, the engine stalls.
Running in the motor
The new motor must not be operated at full load at once. Running-in is necessary for running-in parts.
The duration of the run-in should be 10-12 hours, which corresponds to the time spent on the first 6-8 fuel tanks.
During the running-in of the engine, it is necessary to work at a reduced speed.
After running out of the first two tanks of fuel, you need to check and clean the spark plug electrodes, the tightening of all screws and nuts, including the flywheel nuts, and tighten them if necessary.
After running-in, change the oil in the gearbox.

Lighting
The most popular modifications, unfortunately, are not yet equipped with a headlight, however, some equipment owners themselves regulate this nuance.
It is very easy to make lighting on a walk-behind tractor; for this, a basic electric generator is usually used. The connection is made as follows:
- a device that generates electricity is connected to a button on the steering wheel;
- from the button, lay the necessary wires to electrical equipment (for example, a headlight);
- the wires are insulated in any way from mechanical damage and water (most often a corrugated pipe is used).
If the generator has enough power, the headlight will be bright. With a lack of power at low engine speeds, the light will go out. Some craftsmen change the generator of the walk-behind tractor for a car or tractor.
How to make a light for a walk-behind tractor or mini tractor with your own hands:
In any case, even without using a generator, you can make light on the walk-behind tractor. This requires only a 12-volt battery and an LED lamp. The battery can be taken from an e-bike or scooter.
It is recommended to put it between the gearbox and the engine. According to the scheme given above with an electric generator, a battery is connected. The battery leads to the switch and then to the headlamp or other electrical equipment.
