Help"" no spark.

Get an in-line spark tester (cheap at Harbor Freight). Try spraying starter fluid down the throat to rule out fuel. Did you ground the case of the ignition box? What voltage does coil+ measure (relative to BATT-). You can run a jumper wire from BATT+ direct to coil+ for a short-time test. That bypasses the ballast, bulkhead, key, factory wires.
