Just had Alan from Carbcare out to tune up my carbs, twin Strommys on the estate and single Zenith on the convertible. He did some preliminary checks then set them up, stripping and cleaning as necessary. Blanked off some emissions gubbins on the strommys and adjusted the timing on both cars. Both running nicely now, recommended new leads for the one and a change to electronic ignition on the other. Charged £140 for the 2 cars, and had said parts would be extra (which weren't needed). Then he came with me to test drive both cars. He's local to me and would definitely recommend him. You can post your carb to him for an overhaul.
