If it will help you out any, I posted some tune-up specs in the "gutless 534" thread that may be of some help to you. I just checked and the thread and the post are still there.

In his post, krew said some of his specs showed up differently than what kenny posted. That is somewhat the norm on the older point-type distributors.

If you would get your distibutor tag number--located just below the cap itched in the distributor body and with a 12127 base number--I will be glad to match the tune-up specs with the distributor number for you , if you would like for me to do so.
