thanks for all the advice! just thought everybody would want a followup on what was the problem and what fixed it.I tried grounding all 4 retard terminals and that did not change anything.I reversed the 2 wires from crank trigger-greem & purple wires that go to -M & +M to reverse the polarity and "that fixed it" timing is dead on 35 degrees. but the question is this-what happened or caused this to happen? wired the car 2 years ago with a K & R wiring kit.and we have checked and changed timing several times and it was always right.then one day the car slows down and we start checking things and found this problem.will it happen again and have to switch them back? happy to have found the problem and fixed it so easy. thanks to everybody that chimed in with advice!
