Ok agreed, so how do I make that happen with the timing light? I understand that I hook up the red and black clamps to a 12 V battery. Do I put the spring connector on the spark plug then the spark plug boot on the spring connector?I would stick with a battery.
We are going in circles I think. Yes there is only one adjustment and that adjustment is for timing only and not for setting the point gap. When you move the points mounting plate, you are changing the timing. Leave your feeler gages in the toolbox.
GPZ is correct that when you tighten the screw on the points plate, the timing will usually shift by a small, unwanted amount. You pretty much have to learn how much it will move when you tighten the screw and then compensate for this by making a deliberate misalignment. But lets first get the timing somewhere close to see if that fixes your noise issue. You can worry about perfection later.
Thanks for being very patient with me, I'm hopeful we'll figure it out. Feeler gauge is back in the toolbox, LOL!
