Parts for Sears 69660062: Replacement Parts

This spark plug is a genuine Midwest Engine replacement part for outdoor appliances with small engines, such as lawn mowers, snowblowers, leaf blowers, and wood-chippers. The function of a spark plug is to ignite the combination of air and fuel filtering into the engine, thereby powering the engine; the spark plugs and the surrounding electrical wiring make up the ignition system of an engine.A spark plug might need to be individually replaced when it has reached the end of its lifespan; most spark plugs for small engine appliances last about 25 miles, but this depends on the specific model. When a spark plug is starting to reach the end of its lifespan, the engine's fuel economy will be greatly lowered and there may be ignition misfires. If the spark plugs begin to show signs of damage, this could portend serious damage to the internal combustion engine, so as soon as signs appear of lowered energy efficiency in the engine, the spark plugs should be replaced. Remember to always wear gloves when handling, repairing, and operating outdoor equipment. This spark plug is compatible with the following brands: Briggs & Stratton and Troy-Bilt. This part sold individually.
