12 x 8 for the lifter spindle, the choke ones are very hard to make, I seem to recall 10 x 6.9, Bryan tested the ones I made and said the attrition rate was around 50%, that may be because he was the first to test them and maybe they'd be better once you knew exactly how to fit them. I'll have a try on a set of 500 carbs and see how I do.
