Parts for Briggs & Stratton 091212-1237-E1: Controls, Governor Spring, Ignition Parts

The choke link is used to open and close the choke on the engine. It is used in conjunction with the choke valve to moderate the amount of airflow into the fuel and air mixture, helping to restrict the air when starting the engine. If there is a problem with the choke link, it can cause the engine to have trouble starting, or it might not start at all. If the link is damaged or not properly adjusted, it may not open or close the choke properly. In some instances, it will need an adjustment, but it could also need a replacement. If the current choke link is broken or corroded, it is time to replace it. This is a genuine OEM replacement choke link for tillers, generators, tillers, lawn mowers, and other small engines. Compatible brands include Toro, Cub Cadet, Briggs & Stratton, Simplicity, and Craftsman.

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.

The bell crank link is a genuine OEM replacement part designed for use with certain small engines in lawn and garden equipment. Also commonly used in automotive engines, this metal link is used to connect the throttle to the carburetor and assist in controlling the speed of the engine. Over time, the link can become worn or break entirely with regular use, since it is exposed to constant vibrations and repetitive motion. When the link breaks or malfunctions, the engine will not run properly and there will be no throttle control. That requires a full replacement, which is easier than attempting a repair on a bell crank link. This genuine bell crank link is manufactured by Briggs & Stratton and designed for use on hundreds of engines for lawn and garden equipment. It can be used on lawn tractors, mowers, and other compatible units. The item is made from premium metal and requires a wrench, pliers, and a hex key to replace. Be sure the engine is cool and wear gloves during repairs to protect the hands. This unit is sold as a single item and does not include any additional components or hardware.

If your small engine won't start or has no spark, a faulty spark plug terminal may be the cause. This terminal connects the ignition coil to the plug.
