    Electronic distributor vacuum advance adjustment question

    One of thoughts I've had on this problem is that the springs controlling the mechanical advance are somewhat weaker after about 50 years.

    Anyone know the correct setting is for this spring in the picture below? It looks like those two nuts can retard or advance the base timing. Where is the starting point? Does it matter? I'm trying to get more familiar with the effect of vacuum advance on different driving situations. This dizzy...
