ZAMA WALBRO Carburettor Adjusting Tool / Screwdriver “Hexagon”

Hexagon adjusting tool / screwdriver is used for setting the idle, high and low speed mixture screws on Zama and Walbro carburettors. The tool has a hexagonal tip profile matching the recessed adjustment screws fitted to many small-engine carburettors, allowing the screws to be turned without slipping or damaging the screw head. Without the correct hexagon profile, these recessed screws are difficult to grip with a standard flat-blade screwdriver, making accurate carburettor tuning difficult and risking a stripped screw head. Using the correct hexagon adjusting tool allows the mixture screws to be turned precisely, enabling correct carburettor adjustment.

Suitable for use with:

• Zama carburettors
• Walbro carburettors
