1986 Subaru GL timing and vacum hoses

Just trying to work out is the timing.supposed.to be 0 or 8 for.the crank? also do u have diagrams on this as well as the positions of where the hoses go such as air intake. the belt snapped and im trying to replace and fix it. i can get it to turn on well basically it will only idle properly when its flat sticked. i forgot where the hoses go and just need some basic help
