Parts for Briggs & Stratton 122M02-1012-B1: Air Vane, Blower Housing, Electric Starter, Flywheel, Ignition & Armature, Rewind Starter Parts

Almost all small gasoline engines are started by pulling a starter rope, which initiates the compression in the cylinder that fires a spark plug, igniting the air-fuel mixture that starts a small gasoline engine. Starter ropes may become frayed with use and have to be replaced. Replacing the starter rope is not time-consuming. Begin by removing the shroud, the part of the manifold that covers the starter pulley. After removing the old starter rope, insert one end of the new rope into the pulley assembly and tie a knot in it so it won’t slip out of the slot. Then feed the rope into the starter pulley assembly by holding tension on the rope and using a screwdriver to turn the pulley assembly counter-clockwise until it is taut. Hold the pulley in place with the screwdriver to keep the spring from unwinding as you replace the shroud over the assembly. Keeping the tension on the rope, remove the screwdriver. The only thing left is to attach the starter rope to the mower handle. This starter rope is a genuine OEM manufacturer’s replacement part made by Midwest Engine. It is designed to work on most any Briggs & Stratton, Simplicity, Cub Cadet, or Toro made small engine. These engines are used on lawnmowers, chippers, and other small engines. It is sold individually.

This grip-starter rope is a genuine Midwest Engine replacement part for outdoor appliances with small pull start engines, such as lawn mowers, snowblowers, wood-chippers, leaf blowers, and chainsaws. The grip-starter rope is the piece that allows an appliance user to start the engine by pulling the rope; this mechanism can be referred to as a recoil starter, a starter rewind, or a rope start as well. Any damage to a grip-starter rope will be obvious to the naked eye; while the problems with the actual starting mechanism of a pull start-operated engine might be more difficult to assess and root out, the damage to the actual grip-starter rope itself will come in the form of tears, rips, and general time-worn erosion of the casing material of the rope. If there is significant tearing on the rope itself, this replacement grip-starter rope can serve as a replacement part. Remember to always wear gloves when handling, repairing, and operating outdoor equipment. This grip-starter rope is compatible with the following brands: Briggs and Stratton, Toro, Cub Cadet, and Simplicity.

This boot replacement is sold individually as a single piece and does not include the terminal or any other housing or materials.

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 part is compatible with a wide number of appliances from Toro, Vanguard, Briggs & Stratton, and Lawnboy. It comes sourced from the original manufacturer and ships 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.

This is an OEM replacement part for the recoil pulley and spring assembly, also called the rewind pulley and spring. The recoil starter, which is operated by a rope, will engage the drive cup on the flywheel, which will start the engine when it is pulled. These are commonly found on lawnmowers and similar outdoor equipment. If the rewind begins to bind when pulling the rope, or if it does not rewind easily, it could indicate that a replacement is needed. In addition, if the plastic on the old pulley is worn and cracked, it is a good idea to replace it before it fails entirely. This OEM assembly comes from the manufacturer and includes the pulley and the spring. The pulley is made from plastic, and the spring is metal. The part can be used for a range of machines and brands. The pulley and spring assembly are compatible with lawnmowers, tillers, and other small engines from brands like Craftsman, Briggs & Stratton, Snapper, Lawn-Boy, Toro, and Cub Cadet.

This is a replacement air vane designed for use with a wide range of lawnmower engines. In order to operate, an engine needs both air and fuel. Those also need to be in the right proportions at different times during engine operation. For instance, when first cranking a cold engine, the choke must be closed to prevent air flow, but then the choke must open to allow airflow as the engine increases speed. The air vane pulls the choke open to allow proper airflow. The air vane is made from plastic. As such, it may degrade over time through exposure to high heat. Eventually, it may crack and break. If the engine does not stay running, it may be due to a damaged air vane that no longer pulls the choke open. Replacing a damaged air vane will require a wrench and a screwdriver. Remove the starter rope, discharge chute, gas tank, and engine shroud. Remove the damaged air vane and replace it with the new one, then reassemble the mower. This is a genuine OEM replacement part and is sold individually. It fits Briggs & Stratton engines and is used on Toro and Lawn-Boy mowers.

This is a spring that applies tension to the air vane on Briggs & Stratton lawnmower engines. It’s designed to return the air vane to a closed position when the throttle is closed and allow it to open wider as more air is required. This ensures a proper mixture of air and fuel inside the carburetor. Under ordinary circumstances, the air vane spring should not need to be replaced. If the air vane is violently pulled past its standard maximum point, the spring can be damaged. It can also become damaged over time due to corrosion, particularly if the lawnmower is stored outdoors. Replacing the spring is a simple matter. Just remove the old spring, then install the new spring in its place. With most models, no further disassembly will be required. On some other mowers, you may need to remove the carburetor or motor housing to access the air vane spring. Since it has universal applicability, this air vane spring is used on other engines from Toro, Lawn-Boy, and even Cub Cadet. This is an OEM part sourced directly from Briggs & Stratton, and it is sold individually.
