I have a 1978 I picked up for a song, and I'm in the process of getting her on the road. I did a cam chain adjustment, and the vavle adjustment(.006 intake, .004 exhaust). There is a weird knock that sounded like the right exhaust valve was hitting the valve cover, so for kicks i took the cover off and started it, and the noise pretty much went away. I rechecked my valve clearences and they're good, so I'm a bit stumped. Any idea what might be going on? I wish I would have found my camera for a video...
