stupid Questions sorry..

I'm trying to time my 225 that I just reinstalled into my 74 Duster. The timing light shows on the circle in the middle of the adjustment (see picture). Is this the correct timing? or should it be advanced from center? Also.. (the second picture) I forgot where the hose goes from the valve cover. can anybody tell me? Sorry in advance! Ron :)

P.S. the engine runs but stalls out on idle... still trying to adjust timing and carb.
