Fixed metering needles have to be dead centre in the hole of the jet so take some time to fiddle around with them to get this right. If it is not correct the fixed needles won't fall completely onto the bridge in throat of the venturi of the carb resulting in poor light throttle running.
Please note: the needle choice will depend on range of engine modifications.
