I've checked the gap on the cam lobe associated with cylinder #8. Everything looks good there. Gap looks fine. Of course there is spark at plug lead for cylinder #8. My idea of rotating the dizzy body and shifting the leads accordingly is a means of checking the cap, but of course I end up with the same cam lobe (duh!). At least I know it is not the cap. I did block off the vacuum port near cylinder #8. I'm wondering if my compression reading is misleading me somehow. The leakdown test (I don't have a percentage loss) shows leakage past the rings, but not the valves, although I'm sure there would be some regardless.
