    Although I view this site almost daily I seldom sign in, I just got notice of your message.
    Centrifugal advance depends on three things, the advance head that is fitted, the spring rate and engine rpm. I've only seen one 3-5* head, it was mounted to a '83 (first year of CEC). So one might expect either 3* or 5* advance if a heavy spring was attached and depending on which slot was used. If light springs were attached you could/would double the amount available, so either 6 or 10*, still not near enough as should be expected.

    As far as I know most YJ's are equipped with 6.75 - 7.75 limits and a few had 10-15* the latter a rarity. So the same rule applies, which head, which slot and then spring rate + rpm.

    Only way to be certain is to plot a timing curve, the desired goal would be a range between 32 and 36* total and that should be figured as initial + centrifugal.

    I hope this will help, if you will lead me to the post you've referred to I'll visit it to see what might be added.
