Fuel Tank
Genuine Midwest Engine part
By: Midwest Engine
Part Number: 699374

Fuel is a crucial component for any gas-powered lawn or garden machine. A full fuel tank replacement can be done relatively quickly with this authentic OEM small engine fuel tank. Made for lawnmowers, pressure washers, generators, wood chippers, and other small engine machines, it includes the full tank and a cap. Any issues with the fuel system will lead to problems with the use of the equipment, and this is true whether it is a cracked or leaking fuel line or a malfunctioning fuel tank. To replace it requires the existing fuel to be fully drained from the tank and fuel system. The spark plug wires must also be disconnected before the original tank is removed. Tools required will include pliers to disconnect lines, screwdrivers to remove the motor housing, and socket wrenches to remove the old tank. Replacing it is simple and means little more than handling the pull cord and reattaching the fuel line once it is replaced. This replacement fuel tank works with a variety of brands, including Briggs & Stratton, Toro, Cub Cadet, Lawn-Boy, Craftsman, and Simplicity.

Grip-Starter Rope
Genuine Midwest Engine part
By: Midwest Engine
Part Number: 281434S

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.

Hose Clamp
Genuine Midwest Engine part
By: Midwest Engine
Part Number: 791850

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 part ships individually.

Starter Rope
Genuine Midwest Engine part
By: Midwest Engine
Part Number: 697316

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.

Oil Seal
Genuine Midwest Engine part
By: Midwest Engine
Part Number: 399781S

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. The oil seal is compatible with more than 150 different models of machine. This includes models of lawnmower, snowblowers, pressure washer, leaf blowers, generator, wood chipper, and other small engines. Compatible brands include Briggs & Stratton, Craftsman, Toro, Lawn-Boy, and Simplicity.

Generic Spark Plug Terminal
Genuine Midwest Engine part
By: Midwest Engine
Part Number: 493880S

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.

Spark Plug Boot
Genuine Midwest Engine part
By: Midwest Engine

Flange Screw
Genuine Midwest Engine part
By: Midwest Engine
Part Number: 691108

It also allows the screws to be used in oversized or irregular holes, and it helps to ensure they stay in place. This flange screw also has a hex top. Screws can last for a long time. However, they may become corroded or worn over time and need to be replaced. They could also become lost and need a replacement.

Generic Friction Spring
Genuine Midwest Engine part
By: Midwest Engine
Part Number: 691855

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.
