From memory the Bxuv-2 was jetted to suit the 161's and the bxv-2 was to suit 186's, the base plate with the throttle body swaps over between the two so carbies can have been mixed and matched to nearly anything by now. They may have used a BXV-2 on the 202'a but my book only covers HG series which never had a 202 so i dont know about it.
