Ring Set
Genuine Midwest Engine part
By: Midwest Engine
Part Number: 791787

This ring set is a genuine OEM replacement part sourced directly from the manufacturer. It is made explicitly for lawn and garden engines found on Briggs & Stratton machines. These rings are found between the walls of the cylinder and piston. The rings prevent combustion gasses from getting into the crankcase. Over time, the rings can become worn and damaged, causing loss of engine compression, power loss, and even total engine failure. Signs that the rings are bad include white or gray smoke coming from the exhaust, loss of power, excessive oil consumption, and low or no accelerating power. A ring expander, screwdriver, and socket set are necessary to complete this project. Remove the spark plug wire before removing and replacing the ring set to prevent accidentally starting the engine. Drain the fuel into a clean container. Remove the engine. Locate and remove the piston. Open the piston and remove the rings using the ring expander. Install the new rings in the same order the old ones were removed. Reinstall the piston top, and then reinstall all engine parts in the same manner. Install engine and refuel the machine. This ring set is made of durable metal and is sold as an individual part. The ring set is specially made for small engines manufactured by Briggs & Stratton.

Lawn Tractor Governor Gear
Genuine Midwest Engine part
By: Midwest Engine
Part Number: 793338

This replacement governor gear is a certified genuine OEM part for a lawn tractor or mower engine. The governor is responsible for regulating the throttle. The interaction of the governor spring and governor gear works to position the throttle in such a way that it only allows a set amount of fuel into the carburetor. With less fuel in the carburetor, the engine will run slower. In this case, a slower engine means slower blade rotations. Like any gear, the governor gear has teeth the spin against another gear. Over time, the constant gnashing of gear teeth will cause the gears to wear down and possibly slip out of alignment. Once a gear is out of alignment, it will either stop working completely or degrade more quickly and should be replaced as soon as possible. Replacing the governor gear will require disassembling the engine cover and should be done in accordance with the owner's manual and manufacturer's instructions. This replacement governor gear is a high-quality part sourced from its original manufacturer. It is compatible with engines made by Briggs & Stratton and Toro. This shipment includes a governor gear and the brackets required for assembly.
