Overview:
The Choke Rod MS171 MS181 MS211 is a genuine Stihl OEM part designed to restore smooth, reliable choke operation on compatible Stihl chainsaws. Made from durable metal for strength and longevity, it links the control to the choke mechanism to regulate air intake during cold starts and warm running. A correct, undamaged choke rod helps prevent hard starting and erratic idle by ensuring the choke plate moves cleanly through its positions.

Genuine Stihl part number 1139 185 1901 for reliable compatibility with Stihl service documentation and parts diagrams.
