Re: 289 idle
Charlie,
Run accurate comp test. Any variation might be your culprit. Vac will show wiggly with a slight cam too, so don't jump to conclusions. Valves hanging sounds not good at all, doesn't sound like good machine work, or something odd about oil uptop? If retarding timing a shade and readjusting carb doesn't smooth it out, and compression is even, thoughts of an inaccurate cam come up. Suspicious that it came at get go with rebuilt!
