If you're going to clean your carb, you need to take it apart. You shouldn't need anything more than couple wrenches or screwdrivers to get it apart and put it back together. To clean it, you can buy carb cleaner from an auto parts store, hardware store, or a lot of times, even Walmart will have it. It's only a couple bucks for a can. You should also get a can of compressed air, like the kind you use to clean dust out of your computer.
If you want any kind of instructions, read Fred's Guide. Also, as a general note, it is advisable that you wear eye protection while using carb cleaner. Carbs have a lot of small holes that shoot liquid out at odd angles. You'll squirt the cleaner in one hole, and it'll shoot back out another hole and nail you in the eye. That shit stings, trust me. So yeah, if you're going to use carb cleaner, put on some safety glasses or something.
