you want to start the car and warm it to operating temperature. Once that is done shut the car off and take the spout out, (the little plug that was attached to the distributor that you asked about previous) then start the car back up. With your timing light hooked up properly to the number one cylinder plug wire turn on your timing light and see where the pointer is at on your balancer. Once you know where that is turn the distriduter tell the pointer is at 10 degrees then tighten your distributer back down and shut the car off. Replace the spout and you are done.
