To replace the air filter, locate the air filter cover on the side of the engine, unscrew it, and remove the old filter.

This part is the replacement spark plug for your engine. It measures approximately 2.5 inches by 1 inch.

Lawn Boy Lawn Mower Kit-Needle/Seat

★★★★★

1 Review

PartSelect Number PS8963322

Manufacturer Part Number 398188

This needle and seat kit, also known as a float valve, is found in many types of liquid-fueled lawn equipment, such as carburetors. The valve regulates the flow of fuel into the float bowl. The needle and seat work together to make sure that the valve opens and closes properly, so that it does not leak or overflow. If it is broken, you may notice a strong odor of fuel coming from your machine. Your engine may also run poorly or not start at all. A damaged or corroded float valve can cause fuel leaks, which can be dangerous as they are flammable. To remove the float valve, first disconnect the spark plug wire on your machine. You then need to consult your user manual to locate the float bowl of your machine and remove the bolts or screws securing their cover in place. When you lift off the cover, you will find the needle attached to the float. Using a pair of needle-nose pliers, grasp onto the needle and pull it out of the float. Keep in mind when you are purchasing this OEM-manufactured kit that it comes with the needle and seat together, but the float itself is not included.
