sorry forget what i said i was thinking about an FM12,
F12 timing is on flywheel bottom of bell housing degrees depends on engine number sometimes timing info is on a round sticker on one rocker box,usually between 18 and 22 deg.btdc

you don,t say how old your f12 is,if it,s a late one it needs setting electronically,it dosn,t have a conventional fuel pump,it,s all fly by wire
