Carburetor Adjustment Tool (Octagonal)
The Stihl BG 86 utilizes a proprietary octagonal adjustment screw pattern on the carburetor jets to comply with emissions regulations. Standard tools cannot grip the 8-sided interface, preventing the technician from recalibrating the air-fuel mixture for varying atmospheric conditions. This specialized tool allows for the necessary mechanical rotation of the jets to resolve bogging or stalling issues.
