Does anyone know where the fuel adjust screw is on the Carb, Ive found the idle already, thanks

If it is cutting out at high revs, it can't be fixed by adjusting a screw on the carb.

The idle screw adjusts the idle speed. The fuel air (pilot) screw fine-tunes the fuel delivery between 0 and 1/8 throttle opening.

The only setting on the carb that will affect fuelling with a wide open throttle is the main jet diameter.

Check the fuel tank breather vent and the fuel filter. Cutting out at high revs is more likely to be a fuel starvation problem.
