Description
Overview:
The Choke Knob for Stihl BR340 and BR340L is a genuine Stihl replacement part that restores positive, accurate control of the engine choke. Designed for Stihl backpack blowers and sprayers using the 4203-series engine housing, it fits cleanly on the choke spindle to let you set the choke position for cold starting and warm running. The knob is made from hard-wearing plastic suited to outdoor use, resisting knocks, fuel splashes and repeated operation. It provides a clear grip point for adjusting the air intake, helping you start reliably and prevent flooding. Supplied to OEM specification under part number 4203 182 9501, it is a straightforward like-for-like replacement for worn, cracked or missing knobs on models such as BR340 and BR340L.
