Step #1: Clean the points
Step #2: Set point gap
Step #3: Clean the points again!
These engines are extremely critical about primary ignition current, so make absolutely sure the points don't have oil on them. I like to clean them with alcohol, and a pencil eraser. The rubber eraser has just enough abrasive to polish away any surface oxidation, and the alcohol takes care of any rubber residue. Buff the points thoroughly with a CLEAN pencil eraser, then use a lint-free rag and alcohol to clean up the residue. Set the point gap, and fire it up! Be sure the coil you're using is right for the application. You won't need a ballasdt resistor unless somebody has put a GM-type coil on it in place of the original one. A coil for a mid-60's Ford doesn't need a resistor.
