Thanks Blue Bird, but maybe I didn't make my question clear. I understand exactly what TOHCan meant. What I was wondering is if I was to set my initial timing to specs like usual, then hook the distributor vacuum back up--what should I get for timing with the vacuum hooked up at idle. I'm wondering if my vacuum advance is providing too much advance while I'm at idle.
Maybe I'll have to try unhooking vacuum and setting initial to 12 and see how it runs. Thanks,
