To adjust the idle on a Tecumseh 5 HP engine, locate the idle adjustment screw, typically found on the carburetor. Start the engine and allow it to warm up, then turn the idle screw clockwise to increase the idle speed or counterclockwise to decrease it. Adjust the screw until the engine runs smoothly at the desired idle speed without stalling. Always ensure the engine is in a safe position and follow any specific guidelines in the owner's manual.
