No, normally the older cars run Manifold Vacuum which will advance the timing at idle. Unhooked will drop the timing about 12 degrees. I like 32-36 degrees of total advance, mechanical,base and vacuum combined. That'll change depending on Cam, Head flow numbers, ect. Also be sure the mechanical advance isn't stuck. It needs to advance and return freely. Dwell should be set @ 28-32 degrees. If it's off it will affect timing and that in turn will afect the idle.
