1980 Invader 4/6 Needle & Needle Jet Specs

[Tory944]

  Looking for the "factory" needle and needle jet specs...  going by memory, I "think" the needles were 6DH7, but can't remember what the needle jets were.  P's or Q's?  Any help?  Many Thanks!

Looking at my manual, I am seeing the needle jet as a P-6 (series 159)
