A mechanical shutoff is also called a fuel shutoff valve. The instrument or gadget is installed in most vehicles, lawn mowers, motorcycles, etc. It works by shutting off the supply of fuel to the engine. In some instances, it also doubles as an anti-theft device. That said the device itself is a safety feature which prevents excess fuel from going into the engine which can be due to a number of reasons. The valve itself rarely fails, but when it does, it should only be replaced with a genuine and branded replacement as recommended by the manufacturer.
Replacing the mechanical shutoff can vary in difficulty. It is not something that can be done by anyone who does not have the right tools or experience. However, in some garden accessories and motorcycles, it can be easily done. That said its always a good idea to get the item inspected by a professional to in fact determine that the shutoff valve is faulty because it rarely fails. Also, a professional should be the one replacing the valve in cars and trucks.
