Chasing down a good state of tune for my 948 with a pair of hs2s. They came with DD needles, too rich. I put the GVs from the original herald h1s, still too rich. A bit of research showed there are different strength springs for the dashpots, and if the carbs are "on the large side" for the engine try a lower strength spring. So I've got the "blue" springs, and a set of CA needles which were a lean option to the GVs.



Blue on the left red on the right.
More info when I get a chance to fire it up.
