O.K. Guys---Here's the deal. I was anxious to run the engine to check for oil and coolant leaks, and it did fire and did run, and I did get any leaks buttoned up. I couldn't get it to idle slowly the way I wanted, but it still has the 20 year old quadrajet which has never been rebuilt, leaks, and has been monkeyed with by the previous owner. I had no exhaust system except the manifolds, and it sounded like world war 3 in my garage. I put my timing light on it and discovered the anomaly with the timing mark, as discussed. I was happy to have the engine run, and get the any leaks sorted out. This weekend the car is going to the muffler shop for a complete exhaust system and I am going to buy a rebuilt complete carburater from a shop that specializes in rebuilding carburators. When I get the car back, and the new carb on, I will reexamine this timing issue. It seems to me that I probably am out one tooth on the distributor, but untill I can run the car at a proper idle speed, I am not going to try to reposition the distributor. I am not sure at what speed the centrigugal advance begins to affect things, but it may be that I had the engine running too many rpm's to really check the timing properly. When I get the rebuilt carb on, and things quieted down and slowed down, I will take another shot at the timing.
