Description
Overview:
The Throttle Shutter is a genuine Stihl spare for controlling airflow through the carburettor, ensuring the correct air-fuel mix across the rev range. Built from durable metal to withstand heat and vibration, it restores precise engine speed control and stable running. Designed for Stihl disc cutters, it is a direct replacement for worn or damaged throttle plates on the TS350 and TS360. Correct throttle regulation helps cold starting, clean acceleration, and consistent cutting performance while reducing hunting at idle. Supplied to original specifications, this part fits accurately in the carburettor body and mates with the spindle/shaft for smooth movement and reliable sealing. It is a practical maintenance component for owners and workshops keeping older machines productive and safe.
