Ok, all hooked up. Cranking mightily but no start.

Ran a new wire from the key energized lug on the terminal block before the switchgear. Confirmed it's hot with key on with test light, confirmed I built a good lead (14GA Primary wire) with test light. Connected to (+) on the coil, along with the ignitor red lead. Black ignitor lead is on the (-) side of the coil


Did the low voltage test recommended in the Petronix instructions (Disco red lead from coil, connect red lead to batt via jumper and start). No joy so seems voltage (12V) is not the issue.
Opened up the distributor, checked magnet ring was seated, rotor seated, re-checked air gap of 030. Cap secure and seated. Coil wire seated. All is well there.

Question: Does the (-) side of the Flamethrower need to be grounded? The Bosch coil had that side (-) going to a chassis ground on the fender wall. Seems like I don't have a circuit, no spark.

What am I missing?

Stumped in Rhode Island and trying not to burn down the garage!
