The flywheel key is the component on outdoor equipment that keeps the flywheel connected to the crankshaft. Over time, this key may become damaged or broken, particularly if the engine experiences a forceful stop, like hitting a large stationary object. If the flywheel key breaks, the engine will not start. A slightly damaged flywheel key is noticeable through symptoms like misfiring, backfiring, or having no power. If any of these are occurring, the flywheel key should be replaced to prevent complete engine failure.A flywheel puller tool is required for this repair. Make sure the engine is cool before working on the flywheel. Wear safety gear, including gloves and eye protection. Disconnect the spark plug and remove the blower housing. Remove the flywheel mounting nut and set it aside. Take the recoil starter cup off the mower. Use the flywheel puller to remove the flywheel and access the flywheel key.

This durable plastic ratchet pawl is used on select engines that feature what is known as a Susa starter. In this configuration, the ratchet pawl will be responsible for engaging the recoil starting system. Then, the starting system will allow the engine to fire. Over time, the pawl can become worn or damaged due to regular use. If this happens, the recoil can slip and cause difficulties with starting the engine. If the engine isn’t starting or you can hear it slipping when you try to fire it up, a replacement ratchet pawl could be needed. Be sure to allow the engine to cool before replacing any parts or doing any work and always wear gloves. This replacement is a genuine OEM part that includes two ratchet pawls for various Briggs & Stratton engines on small lawn equipment. This part offers compatibility with over 150 engines from Briggs & Stratton, Toro, Lawn-Boy, and Vanguard by Briggs & Stratton.

This oil seal is a common part engineered to work in engines that power generators, vacuum cleaners, snowblowers, leaf blowers, mowers, and other small engine applications. The seal sits between the crankcase and the crankshaft. It is designed as a barrier to prevent oil leakage and to stop contaminants from leaving the crankcase. When the gasoline engine exhibits diminished power, and especially if it begins to emit oily gray or bluish smoke, there is a good chance the oil seal needs to be replaced. In order to replace the faulty seal, begin by removing the starter housing and taking off the nut that holds the starter wheel to the main shaft. The user will find the old seal on this shaft. Remove it and install the new seal, pushing it into place with the edges of a socket, then tapping it securely into place with a hammer. When choosing a replacement seal, remember to use an OEM genuine replacement part that is guaranteed to match the specs for the original part. This will ensure a quality match and long replacement life. This seal is compatible with Toro, Lawn-Boy, and Briggs & Stratton engines.

This is an inline fuel filter and is an essential part of a fuel system. This part can be found inside the fuel tank or fitted into the fuel line. The fuel filter is responsible for straining particles like water and debris in the fuel so that they won't reach and clog the combustion chamber and eventually reduce the engine's performance. Annoying sputters when starting equipment and uneven idling are incidents that may be related to a clogged fuel filter. To remove a fuel filter, first cut off the fuel supply and then slide the fuel clamps away to remove the filter.

A carburetor on a lawn or garden appliance often has a float-feed chamber or bowl mounted on one side. This is a miniature fuel tank that takes a trickle feed from the main fuel supply. A carburetor is unable to use fuel that is under pressure, so the float chamber keeps everything at atmospheric pressure. When any sort of dirt or debris enters the fuel and air passages, it can cause an array of issues. The debris may enter due to shrinkage of O-rings and gaskets, and that is why a replacement gasket is essential. A carburetor screwdriver is essential when making this repair. Replacing it involves removing several pieces of the carburetor assembly, including a float assembly, inlet needle valve, and the old fuel bowl gasket itself. This authentic replacement carburetor bowl gasket will fit a small engine carburetor bowl on wood chippers, leaf blowers, pressure washers, tillers, snowblowers, lawnmowers, and small engines.

A hose clamp serves the basic purpose of holding together two connecting hoses. This is a crucial job in an engine. Since there are so many connecting tubes and hoses transferring oil and fuel within an engine, a leak could prove catastrophic. It could not only cause the engine to malfunction but could also become a fire hazard. Replacing a hose clamp is an easy job, though the exact process will depend on where the connection is located. A pair of pliers may be needed. This is a genuine OEM replacement part and will work with a wide range of appliances, such as pressure washers, engines, generators, tractors, mowers, blowers, shredders, and chippers from Murray, Toro, Briggs & Stratton, Snapper, MTD, Lawn-Boy, or Simplicity.

This authentic replacement oil seal is for use with a range of small engines. The oil seal is the lower seal that is located in the engine's sump. The seal is made to ensure that there are no oil leaks that could cause issues with the performance of the engine. If the seal is not working properly, it could result in leaks, and the machine may not have enough oil to function properly. Lack of oil can also cause serious issues with the engine. The oil seal is prone to wearing out over time. The seal can become worn and it can start to deteriorate the longer it is used. Owners should make it a point to replace the oil seals whenever they are changing their oil, oil filter, and gaskets. The oil seal is a genuine OEM replacement part, and it is sold individually.

This genuine OEM replacement part is a spark plug terminal for a wide variety of small combustion engines. In a combustion engine, the spark plug generates a small electrical charge that creates enough power to start up the ignition and engage combustion. The plug connects to the ignition through the terminal. Spark plugs generate and then pass a small electrical current through to the ignition. Usually, the main issue with spark plugs is that this current hyper-extends and ends up frying the spark plug. However, if the terminal is damaged, the charge will not pass into the ignitor, and the engine will not turn. If the spark plug can carry a charge but the engine still won't turn, it's likely the terminal that needs replacing. This is an easy repair because the terminal should just snap on and off. If stuck, a pair of needle-nose pliers should make it easier. This high-quality replacement part is compatible with engines from Murray, Toro, Lawn Boy, and Briggs & Stratton. It is sourced from the original manufacturer and ships individually.
