(btw, vented points are a better option if available)
If the condensor is u/s.(i.e. completely stuffed) it will often leave the points burned black.If it still goes, it won't for long. They should be a clean grey. (the only other possibility here is oil getting into the points)
You will probably notice that 6 volt condensors are bigger than 12 volt condensors. (this might be an age/ construction thing, all the same, its a good guide)
Sometimes you can buy one with the microfarad value stamped into the body, and in some cases they were available in different values for the same application.
Having converted to 12 volt you should change the condensor for one made for a 12 volt application. Any one you can get in the hole, and hook the wire up will do. All you need is the thing clamped or screwed to the distributor body, and the wire hooked up to the feed to the points. You will notice that the early jappers had them on the outside of the dizzy. Keep an eye on the points, and try a different condensor if they are tranfering metal faster than they should. The local auto electrician might be able to help regarding capacity up or down. If your coil came from a certain type of vehicle, a condensor of the same capacity, as that vehicles condensor, will do the trick.
I vaguely recall seeing in a wartime training pamphlet, teaching the drivers to make a tempory condensor using a bean can and paper. Maybe someone can recall.
Anyhoo you have it sorted. My guess, from your description, fuel.
Hopefully this has filled a few knowledge gaps, for some of the would be mecanical lurkers out there.

Hi Lynn
The condensor I replaced was about the same diameter as the old one I removed and accoding to the guy at the auto shop would match the new 12 Volt Bosch Coil I installed. Having rechecked everything again all I can say the problem is gone and my Jeep now has plenty of grunt. Tomorrow I am taking her out on a long club run so fingers crossed this will be a good test run.
Thanks to all you MLU guys for the very interesting advice and suggestions. It is fantastic for a novice like me to have so much information to learn and remember. I really do appreciate it. You guys in MLU are so supportive and have always been there to assist and help me and I guess this is why I enjoy my new found, and very addictive hobby.
1st Photo is the old Condensor
2nd Photo is the new installed Condensor.
Cheers
Tony
