Start at TDC and slowly advance the timing while watching the rpm's.  You will get to a point where advancing the timing has no more effect on the idle speed.  That will be where you want to set the initial timing....Then you need to limit the mechanical advance to stay at about 34*~36* total

After you get those numbers you then want to start looking at the rate of advance.
