An "engine running" valve adjustment is the worst possible way to accomplish that little task. It's messy and inaccurate. Use the companion cylinder adjustment procedure with the engine stopped that's been documented here countless times. It involves finding when a cylinder is in the overlap position between exhaust and intake, and adjusting the cylinder halfway around the firing order.
