If they're dying quickly something else is wrong. Have you changed your condenser lately?

(IMG:http://www.914world.com/bbs2/html/emoticons/agree.gif)

Each time the contact points separate, the self induction of the primary winding will cause a spark to arc across the points. This, in time will pit and burn the contacts. Traditionally a capacitor (condensor) is connected in parallel with the contacts to absorb some of the electrical energy between the contacts through charging the capacitor.

You'll (IMG:http://www.914world.com/bbs2/html/emoticons/ar15.gif) any normal size diode you put inline with the point circuit.

Just install a new condensor.... see how that does!
