Compression reading on BS 18 hp intek?

To check the compression reading on a Briggs & Stratton 18 HP Intek engine, you'll need a compression gauge. Remove the spark plug, insert the gauge into the spark plug hole, and crank the engine several times to get a reading. A healthy engine typically shows compression values between 90 to 120 psi, but values can vary based on specific engine conditions and wear. If the reading is significantly lower, it may indicate issues such as worn rings, valves, or a blown head gasket.
