Biased (or spring loaded) metering needles don't require time consuming adjustments to centre the needle in the jet each time they are fitted both during production and during maintenance. To some extent they self centring and all you have to do is fit them so the shoulder is flush with the bottom of the piston in the dashpot.
Please note: the needle choice will depend on range of engine modifications.
