Yes, that passage should be open. You said in a previous post you cleaned the white debris by using a wire wheel on a Dremel tool. Best way to clean a carburetor, including all the fuel passages is to let it soak in some carb cleaner solution. There are various products available for this. After a good bath, blow out all the fuel passages with an aerosol carb cleaner spray, but be careful – when you spray in one hole it will come shooting out another and could fly up right into your face. I wear safety glasses when doing this.
