AHHhhhhh, I see you bought the car(I just posted in the lounge on your other thread). There should be a mark on the distributor for base timing, there's one on mine. Look for a little chisle mark. You could advance the timing without a light but the cpu is supposed to correct this unless you remove the spout, I used to do it all the time. I'd pull off on the side of the road, with my 1/2" wrench, and twist it and see what it would do. I'd add octane boost and I thought I was doing something... this was a long time ago.. heeh... HAVE FUN!!
