Ok I check distributor shaft, and it is silver, not brass colored.

I am trying to write down the highlights of this and go speak with mechanic in next day or two.

What I have taken from this is to see where initial timing is and shoot for 20 degrees or so, with a total of 36.

My MP distributor should be ok if adjusted properly.

Turn idle speed higher (already done).

One thing I read and don't understand is the suggestion to adjust idle vacuum to 4". Not sure what that means. Does that mean set idle where I have that vacuum and not at certain RPM. I guess the mechanic will know, but I am curious.

I will try to have a resolution soon and not drag this out any longer than necessary.

Like I mentioned earlier; mechanic is excellent but not a Mopar guy. I wonder if I should just spring for a Mallory or MSD system that is more easily tuned and familiar to him?
