How much compression is good on a Briggs and Stratton 5hp engine?

For a Briggs & Stratton 5HP engine, a good compression range is typically between 85 and 95 pounds per square inch (PSI). This range ensures the engine can efficiently mix air and fuel, generate sufficient power, and start reliably. If the compression is below 85 PSI, it may indicate worn or damaged components, such as piston rings, cylinder walls, or valves, and the engine may perform poorly or not start at all. To maintain good compression, proper maintenance and periodic checks of engine components are recommended.
