carburator mixture screw adjustment

[kevt]

Hi can anyone tell where and what sort of screwdriver I need to adjust the fuel mixture with the carbs still fitted. Have looked at right angled screwdriver but not sure if they will fit
thanks for your help

You need a special 90 deg 'driver for this job - most you find Halfords and other tool shops aren't thin enough to get at the carbs over the starter motor. 

Not cheap.

Is that a screwdriver that's bent or one with a ratchet type mechanism
