You need to get a timing light from your local auto parts store. Pull the small chip out that comes off the dist. Hook the timing light up ( directions will come with it), lossen the dist hold down (1/2 wrench) just slightly so that it doesn't move on it's own but will move if you turn it. Shine the light on the balancer from the passenger side, you will see the timing marker right above the balancer, move the dist until you can see it reads 12-15 degrees, tighten the dist and turn the car off, plug in the chip. Start the car and go for a test drive. if you hear pinging, then back it down a couple degrees utilizing the same steps. Good luck. Oh, the blalncer might need a little cleaning for a good read.
Or just buy a PMS.
