How do you set the valves on a Briggs and Straton 19.5 HP overhead valve engine?

To set the valves on a Briggs and Stratton 19.5 HP overhead valve engine, you will need the following tools:

* A spark plug wrench

* A flat-blade screwdriver

* A Phillips-head screwdriver

* A feeler gauge

* A torque wrench

Step 1: Remove the spark plug from the cylinder head.

Step 2: Turn the engine over until the piston is at top dead center (TDC). You can do this by inserting a finger into the spark plug hole and feeling for the piston. When the piston is at TDC, the valves will be closed.

Step 3: Loosen the locknut on the valve rocker arm.

Step 4: Insert the feeler gauge between the valve stem and the rocker arm. The clearance should be .006 inches (0.15 mm).

Step 5: If the clearance is not correct, turn the adjusting screw on the rocker arm until the clearance is correct.

Step 6: Tighten the locknut on the valve rocker arm.

Step 7: Repeat steps 3-6 for the other valve.

Step 8: Replace the spark plug.
