Thanks for the info on the "snapping sound". I just don't understand why when I switched the coils around I never heard the sound. Your ideas make sense though. Again, I am assuming that one of the coils is bad. Which brings me to this question.

How do you bench test a 6 volt coil. I have them off and out. Which by the way, I want to offer up this bit of info. When attempting to remove one of them, I found that whoever had riveted the Northeast face place to the base of the coils holder had riveted the face plate through it and into the coil. This is the one I believe failed. Is this proper and/or could this cause it to fail?

Secondly, I read where if you test a coil on the bench from side terminal to side terminal I should see a resistance level of .75 to .81 ohms. I am getting 1.0 on both coil tests. It also says that I should get a reading of 10,000 to 11,000 ohms when testing between either side terminal and the center high tension terminal. I get nothing.

So, I have ordered a standard 6 volt coil to try in each position tomorrow morning. I understand I am looking at 350-550 dollars for two new coils? If anyone has any idea of how to have them rebuilt or where to go to get them replaced it would be much appreciated.

As for the cap. Yes, you are right. I am praying that it isn't the cap as I was told if I can find one im looking at probably another 600 dollars. I removed the cap today and checked the continuity through each spark plug wire to each terminal in the cap and all were good. I do notice on the #3 terminal, (one of the problem cylinders) that the plastic below the terminal inside the cap seems to be scraped away a bit? Does this mean I possibly have a wobbly distributor shaft? Neither I or the mechanic working on it with me seem to think there is excessive play. But why would I be seeing this scraping on a couple of terminals? Can anyone give me some guidance as to what constitutes a bad distributor cap? Further, anyone have an idea where to look for a new one if I should have to replace it?

I am going to pull the distributor in the morning and set the points per Dave's instructions. When I have it out, is there any good indicators as to how to check for excessive wear on the shaft. Anything else I should be checking for when I get it out. Most importantly, any guidance as to what to do or not to do when removing it?
