To adjust the overhead valve on a 5hp Briggs and Stratton engine, first, ensure the engine is off and cool. Remove the valve cover and use a feeler gauge to check the clearance between the valve stem and rocker arm; it should typically be around 0.003 to 0.005 inches for intake and exhaust. If adjustment is needed, loosen the lock nut on the rocker arm, turn the adjusting screw to achieve the correct clearance, and then re-tighten the lock nut. Finally, reassemble the valve cover and start the engine to check for proper operation.

To adjust the valves on a White lawn tractor with a Briggs & Stratton 25.5HP overhead valve engine, first ensure the engine is cool and remove the spark plug for safety. Rotate the engine to top dead center (TDC) on the compression stroke and check the clearance between the rocker arm and the valve stem. The typical valve clearance specification for this engine is usually around 0.005 inches for both intake and exhaust valves. Use a feeler gauge to adjust the clearance by loosening the lock nut and turning the adjustment screw, then re-tighten the lock nut once the desired clearance is achieved.

The valve clearance for a Briggs and Stratton 406777 engine is typically set to 0.004 to 0.006 inches for both the intake and exhaust valves when the engine is at top dead center on the compression stroke. It's important to adjust the clearance when the engine is cold to ensure accurate measurements. Always refer to the specific service manual for your engine model for the most precise information.
