[DeTomaso] Timing Problem

Sat Mar 1 17:39:59 EST 2008

     If my ignition had been timed to 16 degrees at idle with the vacuum 
line plugged,  what should I see with the engine not running while looking 
at the timing pointer and #1 piston at TDC on the compression stroke? 
Should the rotor be pointing 16 degrees before the #1 terminal on the cap or 
should it be pointing straight to the #1 terminal?  I guess this is another 
way of asking if there is supposed to be any advance taking place at idle?
