ZAMA WALBRO Carburettor Adjusting Tool / Screwdriver “Small D Shaped”

Small D shaped adjusting tool / screwdriver is used for setting the idle, high and low speed mixture screws on Zama/Walbro and other small-engine carburettors. The tool has a small D-shaped tip profile matching the recessed adjustment screws fitted to compact carburettors, allowing the screws to be turned without slipping or damaging the screw head. Without the correct small D-shaped 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 small D shaped adjusting tool allows the mixture screws to be turned precisely, enabling correct carburettor adjustment.

Suitable for use with:

• Zama carburettors
• Walbro carburettors
• Other compact carburettors with matching recessed screws
