  If your Husqvarna Snow Blower engine idles or runs roughly, it could be due to several reasons: * The choke might be in the FULL position. Move the choke to the OFF position. * There could be a blockage in the fuel line. Clean the fuel line. * The fuel might be stale. Empty the fuel tank and carburetor, and then refill with fresh, clean gasoline. * There might be water in the fuel.
