Not Getting 12 Volts at Coil

OK folks, now we're getting somewhere. Here's what I understand so far:

The battery is charged and has good cables
The ignition switch works
The starter engages
The neutral safety switch is connected and checks good
The dual-ballast resistor is connected properly
The ECU is new and has an extra ground wire
The voltage regulator is new and has an extra ground wire
The coil is new (checks good ?) and is wired properly but not getting 12V
The coil has a hot lead directly from the battery to the + post to get 12V
The fuel pump and filter are new and deliver gas to the carb
The carb is rebuilt and is getting good gas (even tried starter fluid)
The distributor was checked and is OK
The ignition wires are installed in the proper firing order
The plugs are new and gapped properly
The timing chain is new
The windshield is clean and the tires are aired up

Why won't this ol' girl fire up? What's preventing it from getting fire to the plugs? What's missing from the formula?

The one thing I don't remember you saying, Randy, is whether you actually pulled the cap off the distributor and saw the rotor turn with a quick bump of the starter. Do you know if the old nylon gear on the shaft is engaging the cam?

I'm about out of ideas myself,
Jerry
