Compression testing measures the ability of an engine to compress its air-fuel mixture properly. This compression is crucial for the engine to operate efficiently and effectively. When you pull the starter rope on a small engine, the piston moves down the cylinder, allowing air and fuel to enter the combustion chamber. As the piston moves back up, it compresses this mixture. The higher the compression, the more power the engine can produce.
