To adjust the valves on a 20 hp Briggs & Stratton engine, first, ensure the engine is cool and disconnect the spark plug. Remove the valve cover, then rotate the engine to bring the piston to the top of the compression stroke, aligning the timing mark. Use a feeler gauge to measure the clearance between the rocker arm and the valve stem; it should be set according to the specifications in your engine's manual (usually around 0.004 to 0.006 inches for intake and exhaust). Adjust the clearance by turning the adjustment screw and then recheck the clearance before reassembling the valve cover.
on a 350 engine to adjust valves tighten them down with engine running then back them off until it smooths out probably about a quarter of a turn

A Briggs & Stratton 7.75 HP motor typically holds about 20 ounces (or 0.6 liters) of oil. It's important to check the owner's manual for the specific model, as oil capacity can vary slightly. Always ensure to use the recommended oil type for optimal performance. Regularly checking and changing the oil will help maintain the engine's longevity.
