Description
Fine splined 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 fine splined tip profile matching the finer recessed adjustment screws fitted to some compact carburettors, allowing the screws to be turned without slipping or damaging the screw head. Without the correct fine splined 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 fine splined adjusting tool allows the mixture screws to be turned precisely, enabling correct carburettor adjustment.
Suitable for use with:
- Zama carburettors
- Walbro carburettors
- Other carburettors with matching fine splined recessed screws
