You replaced the Mag coil cap and the dist cap. Is this a distributor system or a mag system?

mag system

Your mag rotor is out of time with the mag cam. There are index teeth on the small gears. It will look incorrect when timed because the impulse coupling snaps the system to make the starting spark. Jim

Take off the cap & rotor, then the 2 screws in that little plate. Turn the mag backwards so the impulse doesn't catch. The C mark on the big gear should line up between the 2 beveled teeth on the small gear. That puts the rotor in time with the cap contacts.

Did you make sure you have the right spark plugs? I can't remember the specific plug but I do remember they should be "non resistor" plugs.
