what i did was put just the #1 wire and plug on and and just kinda flicked the dis. until the plug sparked. then once it sparked i turned it back a quarter inch, not a quarter turn. but it also could be that i am using a HEI dis and have never set timing with one. it had to be turned way advanced, and it is a vacuum advance.
and yes Cobalt at one point i did think i was going to lose my eyebrows. lol
