    I maintain that at least 90% of the time, dirty breaker points are the no-spark problem on those. Take the points completely apart and de-grease and polish each contact individually. Reinstall and set gap to 0.020″. Do one set at a time so you have a sample of how they go together, and don’t lose any of the little insulators.
