Just did a complete rebuild on my 68 Camaro 327. New everything. After it ran for a week or so, it developed a slight miss, nothing major, but enough to know it wasn't right. It would even backfire slightly through the carb upon quick short acceleration. So checked timing, dwell, points. All O.K.. Then I pulled the plugs and they were black powdery looking. Not oily, just dry black soot and they all looked the same!! Put new plugs in and the car purrs like a kitten. No backfire, no miss. Is this normal on a new rebuild, or should I be cautious of a problem somewhere.
Thanks for any comments. [img]graemlins/clonk.gif[/img]
