This replacement exhaust gasket is a certified genuine OEM part for a lawn tractor engine. This gasket helps to seal off the exhaust from the carburetor. For an engine to run, it must first mix fuel with air to prepare the fuel for combustion. By sealing off the exhaust, this gasket allows for fresh air to enter into the carburetor from outside the engine rather than from the exhaust. Gaskets often degrade over time due to the stress of pressure and heat. If the exhaust gasket breaks its seal, it can affect the engine's overall performance. Be on the lookout for an especially noisy engine that doesn't provide as much power and is less fuel efficient. There may also be a noticeable burning smell coming from the engine. To replace the exhaust gasket, use a socket wrench and wrench set to remove the air filter and blower housings, then remove the exhaust manifold and switch out the gasket. This replacement exhaust gasket is compatible with engines made by Toro, Briggs & Stratton, Murray, Snapper, and Simplicity. It comes sourced directly from its original manufacturer and does not include any additional hardware.

This pushrod serves a vital part of the camshaft in a lawn tractor’s engine. As the camshaft spins, the pushrods open the engine valves to intake air and release the exhaust. Without a functioning push rod, the engine cannot run properly. There are two push rods in an engine made of steel and aluminum, respectively. This item is the longer, 6in steel rod. Be sure to replace the correct part. Pushrods should last for 200,000 miles of wear and tear but can be broken by harsh use. The pushrod needs replacing when the engine starts misfiring or will not run at full power. The most common problem is a bent pushrod. This part is a genuine OEM replacement part straight from the manufacturer. This item is made by Briggs & Stratton, though Toro and Vanguard both make identical parts. Again, this is the steel variety of pushrod, and it is sold individually. Aluminum pushrods are sold separately.

This pushrod is a metal rod that is used in overhead valve engines. It transfers the motion of the camshaft within the engine block to the valves within the cylinder head. One end of the rod is fitted with a lifter that contacts the camshaft. Rods can slip or wear with time and may even break or bend. The pushrod is used within the exhaust valve, and it may become stuck or damaged and require replacement. However, it is not always the rod that is the root of the problem. Malfunctioning valves or bad fuel can be behind bent or broken rods, so a bit of diagnostic work is best done while making the replacement of the rod or associated valves. This is an OEM aluminum push rod replacement designed for use with engines on several Briggs & Stratton, Toro, and other lawn tractor engines. This durably made pushrod sold individually.

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.
