How do you set valve clearance intake and exust qg 15?

To set the valve clearance for a QG15 engine, first, ensure the engine is cold. Rotate the crankshaft to align the timing marks to the top dead center (TDC) for the first cylinder. Using a feeler gauge, measure the gap between the rocker arm and the valve stem, and adjust the clearance by loosening the lock nut and turning the adjusting screw until the desired clearance is achieved. Repeat this process for both the intake and exhaust valves, following the manufacturer’s specifications for the correct clearance values.
