S/N 3480000. Compression 105 psi both cylinders. Stator coils: High 182 ohms; Low 4780 ohms: Ignition coils: Primary 0.4 ohms; Secondary + or - to tower no reading(Spec 800-1100 ohms), + or - and tower to ground 563 ohms. Installed new points and condenser. Good blue spark across 3/8" gap. Ran great for 10 mins in tank, then died.....no spark at either cylinder. Questions: 1. How can I test the ignition module 336-4516A2? 2. Why no reading on ignition coil secondary? Any help is greatly appreciated. Thanks. Jerry
