Welcome to the QB from SE Michigan! You are t he second newbie from TX today that I have said hello to!! Snarling can be from many issues. Any thing from a simple thread caught in the bobbin casing or under the throat plate to tension issues and many things in between. Holding the thread is a great start as suggested above. IF that doesn't work check to be sure you don't have a piece of thread caught in the bobbin area or under the throat plate. Then check the tension especially it it is looping. You may need to check the upper tension. If all else and other suggestions that may come this way don't hesitate to take it in for repair. Again welcome aboard and jump right into the fun!.
