After a few calls to Tracy and a little help from Buly I tracked down the problem(s) and last night. She went BrrrraaaaPPP for the first time at 9pm. What a beautiful sound! Not just because I wanted to hear it, but also because it truely IS a beautiful sound. Somewhere between a deep growl and race car whine it spoke of power and precision. I'm looking forward to hearing it again today - this time I'll turn the fuel pump on so I get more than 6 seconds worth. :) The problems were - 1. Crank Angle Sensors too far away from trigger wheel - added a thin washer 2. CAS wiring reversed - pulse should be positive as you approach quickly with steel. 3. Cranking voltage/speed too low 4. And the winner......12v supply to lead coils suspect. It tested as 12V, but the plugs wouldn't spark. When I cross wired to the trailing coil supply the plugs sparked. I thought volts were volts. Apparantly not. Many thanks to Tracy for his instant availability, patience and encouragement.
