Bob,
I had the same problem when I rebuilt my SU HS4's. Accidentily i had
put the, new, needles too far upward into the carb piston. The needle
base should be flush with the carb piston bottom.
OTOH, it could be that you did it right, but you still experience the
carbs to be rich. Maybe a solution could be to lower the needles a
little bit, say 1/64", so that the mixture with the needle in 'idle'
position is leaner.
If this doesn't help i suggest to check if your needle/jet
combination is suited for your particular car.
Good luck,
Bert Otten
