it will help you trouble shoot your idle problem but I do not believe it out lines how to find a vaccum leak it might in the general section but not sure. usually you can hear a vaccum leak its a hissing sound. but also if you spray carb clean around the intake area if you have a vaccum leak the idle will change when the carb cleaner hits it.
