**SOLVED** The starter mechanism didn't have the spring attached to retract the starter completely. Ironically, there was a spring laying up near the radiator that I had seen before but hadn't given any thought to. Also, the engine started and ran perfectly for about 10 seconds! Quiet and smooth! We can't get it to do it again though. There is something up with the distributor. Having some intermittent spark issues. But after hear the engine run like it did, it sounds very solid. Also, when it did start, it did it instantly. No hesitation, or anything. Ryan hit the starter and it started immediately. Stunned us both. So, looks like the engine is staying!!!
