Well, you may not be a guru, but you're smarter than I am! I'd disconnected power to the tach with no joy. Tried starting it after disconnecting the tach lead from the HEI, started right up! Very happy about that, but still puzzled what caused the ignition to quit with the tach hooked up. Any further thoughts? It was really nice having the tach functional for those first two minutes!
