Installed a MSD 6al and an MSD dist. in my 83. When I hooked up the stock tac. to the tac. output from the MSD my tac. reads nothing...... When I hook it to the coil (MSD blaster) the tac. seems ok off idle but at idle it jumps from 650 rpm to 2000rpm. The motor speed does not change with this jump. Any ideas?????
