An incorrectly set ignition timing leads to incomplete combustion of the fuel-air mixture entering the engine cylinders. This is reflected in the operating fuel consumption, in the direction of its increase. In addition, the remaining fuel flushes the lubricant from the cylinder walls, increasing the wear rate of the piston group. In particular, and, reducing the motor resource of the engine as a whole.

Instructions
Step 1
To check the accuracy of setting the ignition timing, it is necessary to sharply press the accelerator pedal while driving on a flat road at a speed of 40 km / h. After performing this action, a characteristic detonation knock should appear from the side of the engine compartment, which stops at the moment the machine develops a speed equal to 60 km / h. In cases where everything happens exactly like this, the ignition timing is set correctly.
Step 2
But, if the detonation in the engine has not stopped, and continues after the car has set a speed above 60 km / h, then this factor indicates that the "early" ignition is set.
In order to correct the ignition moment, it is necessary to stop the car and turn off the engine. Having raised the hood, and, having released the nut of fastening of the breaker-distributor, turn the "distributor" counterclockwise by 1-2 mm, then tighten the nut of its fastening.
Step 3
It is possible that the knocking knock of the engine will stop until the moment when the car reaches sixty-kilometer speed. In this case, the ignition timing is set with some delay. The adjustment is carried out in a similar way as described above, with the only difference that the breaker-distributor rotates around its axis along the clock - by 1-2 mm.
Step 4
After one or several stops along the way, the most accurate setting of the ignition timing is carried out.
