The power of the old motor can be reduced due to the deterioration of the compression, which is caused by the wear of the parts: cylinder, ring, and piston. The more wear, the lower the compression. The scale of the engine’s auto-compression ratings is as follows:

12 kg / sq. M. cm – excellent compression;
10 – mediocre;
9 – bad;
