Not exactly sure how to interpret "we are getting power from the distributor" along with "no spark". Tell us more about the checks you have run. Did you check for spark at the sparkplug end of a wire? What are you measuring when you say there is power at the distributor. Please confirm that you have a distributor and NOT a magneto, as the course of action might be different. If you truly have a "spark" at the distributor, then something between rotor, cap, wires, and plugs is causing it not to fire at the cylinder. If you are measuring coil voltage at the distributor, then along with all the possible culprits above, you need to add points and condenser. Tell us more about your trouble-shooting, and we can guide you to the cause more quickly.
