This replacement friction spring is a genuine OEM part meant for any number of small appliance engines run using a starter rope. This spring absorbs large amounts of kinetic energy that could damage the starter rope pulley system. It helps keep the pulley from being overstretched, which would create enough pressure to break the entire system. This spring sits at the center of the pulley system and creates resistance as the user yanks the starter rope. Friction springs can become worn out after repeated use, especially if a user tends to yank the starter rope quite forcefully. The most obvious sign of a worn of friction spring is if the pulley system lacks any resistance. As the user pulls the cord, they should feel a little pull back, but if the friction spring is worn, there will be much less resistance. Replacing this part is straightforward and will only require a screwdriver. Simply open the pulley system, carefully remove the old spring, and install the new one.

This replacement valve seal is a genuine OEM part for a lawn tractor or mower. The valve stem is a type of valve that transfers oil into the cylinder and then immediately reseals due to the pressure in the chamber. However, if the seal is damaged, it will not close and oil will leak into the cylinder. If this happens, the cylinder head may become overly lubricated and not run well. This seal helps prevent that from happening. It fastens to the intake valve and valve stem keeper. Seals will naturally wear out over time due to stress and exposure to corrosive oxidizing agents in an engine. When this happens, the valve will leak oil. To test if the valve seal is compromised, look for whitish-grey smoke that indicates burning oil and also measure to see how much oil the engine is consuming. If the seal is breached, use a screwdriver and socket wrench set to change out the part. This top of the line replacement valve seal is compatible with Briggs & Stratton, Toro, and Lawn Boy lawn tractors. It is sourced from the original manufacturer and ships individually.

If the key is no longer working, it can be due to this part being damaged. This should be a fairly simple repair and should only use common household tools. This is a genuine OEM replacement part. This part is sold individually and is sourced directly from the manufacturer.

This is a fuel cut-off value that is used in over 150 different small gasoline-powered engines. Those devices that have this value include power vacuums, leaf blowers, pressure washers, and generators. The fuel cut-off valve is a safety feature that sits on the bottom of the fuel tank. In situations where the engine must be cleared of gasoline, this valve is very useful. It allows the gasoline in the fuel line to continue to the carburetor and to be combusted in the cylinder. Once the engine block is drained of gasoline, no further ignition of fuel is possible until the cut-off is reactivated. Although it is out of the way of casual contact, the cut-off can be bumped and damaged by contact with other tools, hoses, or debris. Also, since it is a narrow passage through which gasoline passes, it is possible for contaminants to jam the flow and create a blockage. If the tank is full of gasoline and the carburetor is functioning normally, an engine that won't offer to start at all may be the victim of a faulty cut-off fuel valve. This OEM genuine replacement is compatible with Toro and Briggs and Stratton engines.
