Re: When to shut off fuel
There is another potential safety hazard no one has mentioned yet. If you are using an aircleaner with a paper filter that is below the carburetor throat, a leaking needle valve can allow gas to soak the filter. If you have a backfire occur, it can start a sizable fire in the engine compartment. The previous owner of my roadster had it happen to him. He was lucky that it only blistered some paint.
