It is usually above the float in the little bowl at the bottom of the carb.
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.

My 5 horsepower Tecumseh on my John Deere snowblower takes : ( 20 ounces / 600 ml )
one quart. Use the oil dipstick!!
Initial setting: Close needle valve (rotate clockwise) until just seated (DO NOT FORCE) and then open (turn counterclockwise) 1-1/4 to 1-1/2 turns. Start engine and let it warm up (about 5 minutes). Fine tune: After engine has warmed up, slowly close needle valve until engine starts to stall for lack of fuel, then slowly open needle valve until engines starts to stall from flooding. Set the needle valve at midpoint between the two. If the engine starts to sputter while in service, open needle valve 1/8 to 1/4 turn for a slightly richer mixture. How do you adjust a float on a Tecumseh carb?
My book for my John Deere snowblower , which has a 5 horsepower Tecumseh engine , shows to use the Champion RJ17LM spark plug
