To rebuild a Briggs and Stratton OHV engine, start by disassembling the engine carefully, noting the order and orientation of parts. Clean all components and inspect them for wear or damage, replacing any faulty parts such as gaskets, rings, or valves. Reassemble the engine using a torque wrench to ensure proper tightness of bolts, and follow the manufacturer's specifications for reassembly. Finally, perform a thorough check of the fuel and lubrication systems before starting the engine to ensure it runs smoothly.

how to Change oil on a Briggs and Stratton 6.75 HP
The 14.5 hp ohv Briggs & Stratten engines require a 0.30 in gap
try .030 unless it is an Intek OHV and then 0.020"
The valve clearance on a Briggs and Stratton 21 HP OHV engine is typically set to 0.005 inches for both the intake and exhaust valves when the engine is cold. It's important to check the specific model's service manual for any variations or specific adjustments. Proper valve clearance ensures optimal engine performance and longevity.
0.004" would be correct. See the YouTube link attached below for the procedure.
You can adjust the valves on your 17 horsepower Briggs and Stratton engine by turning the adjustment screws. The adjustments screws will determine how much fuel goes into the piston chamber.
You do not state if it is a single or a twin (which it could be of either at that HP) so links to each below:
There is not such conversion of displacement to HP. You have what is basically a 17 cu. in engine and that would seem to be and 8 to 10 HP engine in an OHV configuration.
