Well I have one of those fancy timing lights that lets you dial in the advance. So at first I freaked. 35 degrees at idle. Then the old school came back and I plugged the vacuum advance. So initial is 22 freeking degress. I am not going to do anything until I can get a wrench on the adjuster and back this sucker off at least 8 degrees. My guess it will not even idle at that though. Never worked with a holly so I may need some help here. I presume idle is still just butterfly position or is there a separate idle circuit.
