I *think* I have the RA needles in my 2000 right now (Z-therapy carbs in the
car now), but I can't read the numbers on the needles. I can tell you that
the car screams down the road and gets about 21-24 mpg with those. I had
the original N17s in the previous set of carbs that were rather doggy, but
got 27-35 mpg...Those needles had some shiny spots from PO misadjustment, so
replaced with a set of N25 which gave better performance and only about
25-30 mpg.
I have a freshly rebuilt U20 with Jethot coated header and Gary Boones EI
distributor.
Good luck!!
