Can you run a cylinder balance test? Loosen the spark plug wires and with the engine idling , remove one wire at a time, engine should continue to run. If it dies, when one wire is removed, the opposite cylinder is not firing. Check cylinder for, if it has spark and is firing, check the valve movement, a pushrod my be off!
