If the choke knob on a Stihl BR 600 won't open when pulling the trigger, follow these steps:

1. Check the Throttle Cable – Ensure the throttle cable is not too tight. If it is pulling down the choke latch too much, it may need adjustment.
2. Adjust the Trigger Screw – There is a flat-head screw on the trigger that can be adjusted. If adjusting it does not solve the issue, further inspection is needed.
3. Inspect the Choke Mechanism – Make sure the choke knob can move freely and is not obstructed.
4. Verify Proper Installation – If a new carburetor was installed, ensure the throttle and choke linkages are correctly connected.
5. Test the Choke Knob Movement – The choke knob should move freely between positions and automatically return when the throttle is engaged.

If the issue persists, consider seeking professional servicing to check for misalignment or incorrect assembly.
