Which needle will I use in my BS32SS carbs

[Suzuki_Don]

Don, I spoke with Bill, he thinks the number diff might just be the fact that it has grooves v.s. single groove (i.e. same taper). Needles are tapered and they bench mark them every 10mm, so if you are careful and use a caliper you can compare thicknesses along the length in a couple of spots to confirm what Bill is saying.

The suggested tuning is to get the mains set by pulling hard full throttle to redline. Then adjust the needle height, to adjust for any flat spots or bobbling in the mid range. Bill taught me everything I know and I still don't know what he does.

Jim I measured both needles with a vernier at each 10mm from the tip and they were all but identical. So no reason why either should not work properly.

Thanks for your other info in the tables.
