This is an MTD rocker arm. The rocker arm works in conjunction with the engine and head. The job of the rocker arm is to push the intake valve open, allowing fuel and air to enter the cylinder. Since the rocker arm is a part of the head gasket system, any damage can cause the engine to run extremely weak. There could also be a noticeable clicking or ticking noise originating from the engine area of the mower. A visual inspection of the rocker arm will confirm any damage. Begin the repair by removing the muffler guard. After removal, move to the valve cover and remove that guard as well. Disconnect the fuel and air lines running to the head. Remove the spark plugs in the valve section. Finally, the rocker arm can be removed using a socket wrench. Repeat these steps in reverse to install the new rocker arm.This product is sourced directly from the manufacturer as a genuine OEM part. The component is available individually, separate from the original machine. This part is compatible with MTD and Cub Cadet brand equipment.

This is a small engine spark plug positioned in the engine cylinder head. It supplies the spark that will ignite the air-fuel mixture to enable an engine to produce power. This particular spark plug is designed with superior corrosion resistance and dependable performance. Small but mighty, this component allows for increased conductivity and heat control. If the spark plug is damaged or in poor condition, many problems may arise in equipment, including sudden stop while running, overheating, and excessive gas consumption. Replace the spark plug by disconnecting the spark plug wire first, then use a socket driver or wrench to remove the spark plug. Install the new spark plug by turning it by hand initially to avoid cross-threading. If it doesn't twist anymore, use a deep socket wrench or socket driver to tighten the plug until snug. The spark plug can also be used to tune up outdoor power equipment or improve a small engine. This part is recommended to be replaced once per season.

This carburetor insulator is a genuine MTD replacement part for appliances with small engines, such as lawn mowers, lawn tractors, lawn trimmers, snowblowers, chipper shredders, tillers, and leaf blowers. The function of a carburetor insulator in a small engine appliance is to maintain a lower temperature for a running engine and to keep that heat away from the carburetor, the purpose of which is to mix the air and fuel in order to start the engine. A functioning carburetor insulator will prevent the engine from overheating.A broken or non-functioning carburetor insulator will likely not prevent the engine from operating, but it might slow down its power or reduce its fuel economy due to compensation from overheating. An engine with a damaged carburetor insulator might take in more fuel than usual or allow in unmetered air. An unmetered air leak can cause damage to the engine in the short-term so if there appears to be visible damage to the carburetor insulator, it should be replaced as soon as possible.This carburetor insulator is compatible with the following brands: MTD, Cub Cadet, Yard Machines, and Craftsman.
