| 1. To check the centrifugal regulator. |
| 2. To connect the vacuum pump to the regulator. |
| 3. To bring the engine to the speed of rotation of 2500 rpm and to measure the size of a centrifugal advancing in degrees concerning a point "0" on a plate. |
| 4. To establish discharge in the range of the values given in the characteristic and to bring the engine to the speed of rotation of 2500 rpm. |
| 5. To measure the size of a corner of an advancing of ignition and to take away earlier measured size of a centrifugal advancing that will give the size of a vacuum advancing. |
