Mechanical Inspection: Compression

Check engine mechanical condition with a compression gauge, vacuum gauge, or an engine analyzer. If compression gauge is used, see COMPRESSION SPECIFICATIONS table. Ensure engine cranking speed is about 300 RPM. If vacuum gauge is used, check for low or unstable vacuum condition. If engine analyzer is used, see manufacturer's manual for specific instructions.
