Corky,My manual says 30 degrees and I even went to check it out. The only thing Icould think as that your man wants 28 to make it have a little less advancefor less snap back without the impulse mags. Many do not know it but theimpulse mags also RETARD the ignition almost to O degrees BTDC to make forno snap back starts.Chris----- Original Message -----
