do not change anything richie , 138,42,65 is the right choice :
main 138 , slow (idle) 42 , power 65 . if you have already 42 & 65 just phone to mattew and tell him , he will certainly accept your cancel about power & slow jets . sorry for that richie !

exactly , because they are covered with a protecting stuff and may be they will be slippery a bit , so drive with fresh eggs under your break pedals ................
