To add to 36 Coupes excellent comment, if the condesnor value isnt close to the correct capacitance, you will observe like a pit/crater on one set of the contact points versus a build up on the other point. If however the capacitance is the correct value, while theres still normal burning and carbon, you wont see the pits versus build ups so much i.e. even wear on BOTH sides. That has to do with the condensor being the correct value to correspond to the coils inductance.....
So while she can still fire with the incorrect capacitance value, its best for spark quality and points longevity if its correctly sized and not several factors off correct.
CONDENSOR RATING DOES INDEED MAKE A DIFFERENCE
Hope this helps
