Additional Information
This MTD throttle trigger offers responsive control of engine speed for select line trimmers. It replaces part numbers 791-00042 and 791-00058. The trigger enables smooth acceleration and precise trimming, improving usability and fuel efficiency.
Typical symptoms of a failing throttle trigger include poor throttle response, engine surging, or the inability to rev the engine properly. Replacing a damaged or worn throttle trigger can restore consistent performance and enhance safety while operating your line trimmer.
Installation is straightforward and can be completed with basic hand tools. Always disconnect the spark plug before servicing your equipment, and wear gloves to protect your hands while working with small parts and springs. Confirm part compatibility with your specific trimmer model to ensure proper fit and function.
