Parts for Briggs & Stratton 123672-0147-E2: Cylinder Head Parts

This is a cylinder head gasket. It creates a seal that air can't move through. When the cylinder head gasket is working correctly, it prevents leakages of oil or air. As time goes on, the cylinder head gasket will start to wear out and will need to be replaced.If the cylinder head gasket is worn out or damaged, the replacement will require the use of a wrench. The process involves moving the tool to a stable surface and disconnecting the spark plug wire. The engine will need to be disassembled to get access to the head gasket. Remove it from the engine and replace it with a new component. Make sure to reassemble all parts before using the tool.This is a genuine OEM replacement part that is directly sourced from the manufacturer. It is sold as an individual part. The cylinder head gasket is made to be used with lawn mowers, leaf blowers, tillers, and pressure washers manufactured by Cub Cadet, Briggs & Stratton, Simplicity, and Toro.

Engine running rough or losing power? A worn exhaust valve may be the culprit. This valve controls exhaust gas flow for proper engine performance.

Replace a worn valve retainer if your engine has compression loss or valve train noise. This washer-shaped part secures the valve spring lock on the valve.

Engine runs rough or valves aren't opening correctly? This metal valve tappet converts camshaft rotation to linear valve motion. Direct replacement part.

This is a genuine intake gasket replacement that is designed for use in certain lawn mower engines. This specialty intake gasket is what is responsible for creating the seal between the carburetor and the breather tube so that no gases or fluids leak when they pass between the two. This gasket is subjected to constant high pressure, vibrations, and extreme temperatures, and over time it will need replaced. Gaskets are generally considered a part of routine maintenance on most engines, and many owners will choose to keep a few extra on hand in case of an urgent repair need. This genuine OEM intake gasket is manufactured by Briggs & Stratton and designed to offer an identical replacement for the original gasket that came on the new unit. It is compatible with lawn mower engines in models from Briggs & Stratton and Toro, and will fit on over 150 different engine models in lawn mowers from these brands. The intake gasket is made of durable composite material. It is also a good idea to replace gaskets when servicing the carburetor to ensure a proper seal after reassembly. Be sure to use the right tools to install this part so that it isn't damaged in the process.

Spark plugs work by providing an electric spark in a combustion chamber, igniting the mix of fuel and air that allows the engine to turn and propel a drive shaft. Insulated with ceramic to make sure the electric charge flowing through it is properly discharged, the plug is screwed into the cylinder head. The movement of the piston sucks fuel into the cylinder until it reaches the optimum level, the compression triggering the spark plug to send a pulse that ignites the fuel and pushes the piston to the back of the cylinder. This process is repeated hundreds of times a minute in an internal combustion engine. Eventually spark plugs simply wear out, particularly if they are not properly gapped, if the fuel mixture is improper, or the engine is subject to excessive use. This plug is compatible with most lawnmowers, small engines, and pressure washers made by Briggs & Stratton, Cub Cadet, and Toro. The plug itself is a guaranteed OEM part and is sold individually.

Flange screw for lawn and garden engines. Distributes connection force over a larger area. Replace if threads are stripped, head is damaged, or screw is missing.

Rocker arm stud for lawn and garden engines. Secures the rocker arm to the cylinder head. Replace if stripped, broken, or missing for proper assembly.

This exhaust gasket is a genuine Midwest Engine replacement part for appliances that use small engines, such as chipper shredders, snowblowers, leaf blowers, and lawn mowers. The function of an exhaust gasket is to seal off the carburetor from the exhaust tube in order to protect the engine from the accumulation of dirt, debris, and gunk within the inner workings. The exhaust gasket may require replacement over time from general wear and tear. If the exhaust gasket is not sealing, allowing dirt and debris to accumulate within the carburetor and leaving the exhaust tube exposed, the part should be replaced immediately. Evidence of a damaged exhaust gasket could also manifest in the form of oil leakage, black smoke arising out of the exhaust tube, and unusually low pressure from the combustion when using the appliance. Any of these symptoms can be attributable to multiple factors, so one should assess if the exhaust gasket is responsible before ordering a replacement.This exhaust gasket is compatible with the following brands: Briggs and Stratton, Cub Cadet, Toro, and Simplicity. This part sold individually.
